The first and second depended processes are both depended processes, but are not the same depended process.

In one embodiment, as shown in fig. 1, a schematic diagram of the internal structure of a terminal is provided. The terminal includes a processor, a memory, and a display screen connected by a system bus. Wherein, the processor is used for providing calculation and control capability and supporting the operation of the whole terminal. The memory is used for storing data, programs, and/or instruction codes, and the like, and the memory stores at least one computer program which can be executed by the processor to realize the process processing method suitable for the terminal provided in the embodiment of the application. The Memory may include a non-volatile storage medium such as a magnetic disk, an optical disk, a Read-Only Memory (ROM), or a Random-Access-Memory (RAM). For example, in one embodiment, the memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a database, and a computer program. The database stores data related to a process processing method for implementing the above embodiments, for example, information such as a name of each process or application may be stored. The computer program can be executed by a processor to implement a process handling method provided by various embodiments of the present application. The internal memory provides a cached operating environment for the operating system, databases, and computer programs in the non-volatile storage medium. The display screen may be a touch screen, such as a capacitive screen or an electronic screen, and is configured to display interface information of an application corresponding to a foreground process, and also may be configured to detect a touch operation applied to the display screen, and generate a corresponding instruction, such as a switching instruction for performing foreground and background applications.

Those skilled in the art will appreciate that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration relevant to the present application, and does not constitute a limitation on the terminal to which the present application is applied, and that a particular terminal may include more or less components than those shown in the drawings, or may combine certain components, or have a different arrangement of components. For example, the terminal further includes a network interface connected via the system bus, where the network interface may be an ethernet card or a wireless network card, and the like, and is used for communicating with an external terminal, such as communicating with a server.

In one embodiment, as shown in FIG. 2, a partial architecture diagram of a terminal is provided. The architecture system of the terminal includes a JAVA space layer 210, a local framework layer 220, and a Kernel space layer 230. The JAVA space layer may include a freezing and unfreezing application 210, and the terminal may implement a freezing policy for each application through the freezing and unfreezing application 210, and perform a freezing operation on a related application consuming power in the background. A resource priority and restriction management module 222 and a platform freeze management module 224 are contained in the local framework layer 220. The terminal can maintain different applications in organizations with different priorities and different resources in real time through the resource priority and restriction management module 222, and adjust the resource groups of the application programs according to the requirements of the upper layer, thereby achieving the effects of optimizing performance and saving power consumption. The terminal may allocate, by using the platform freezing management module 224, the task that can be frozen in the background to the freezing layers corresponding to the preset different levels according to the length of the freezing time, and optionally, the number of the freezing layers may include three, where: CPU limited sleep mode, CPU frozen sleep mode, process deep frozen mode. The CPU sleep-restricted mode is to restrict CPU resources occupied by related processes, so that the related processes occupy less CPU resources, and the vacant CPU resources are inclined to other processes which are not frozen, so that the occupation of the CPU resources is restricted, and the occupation of network resources and I/O interface resources is correspondingly restricted; the CPU freezing sleep mode means that related processes are forbidden to use the CPU, the occupation of a memory is reserved, and when CPU resources are forbidden to use, corresponding network resources and I/O interface resources are also forbidden to use; the process deep freezing mode is to further recycle the memory resources occupied by the relevant processes except for forbidding the use of CPU resources, and the recycled memory can be used by other processes. The kernel space layer 230 includes a UID management module 231, a Cgroup module 232, a Binder management module 233, a process memory recycling module 234, and a timeout freeze exit module 235. The UID management module 231 is configured to manage or freeze resources of the third-party application based on a User Identifier (UID) of the application. Compared with the Process control based on the Process Identifier (PID), the unified management of the resources of the application of one user is facilitated through the UID. The Cgroup module 232 is used to provide a complete set of resource restriction mechanisms related to Central Processing Unit (CPU), CPU set, memory, input/output (I/O) and Net. The Binder management and control module 233 is used for controlling the priority of background Binder communication. The interface module of the local framework layer 220 includes a binder interface that is issued to the upper layer, and the framework or application of the upper layer sends a resource restriction or freezing instruction to the resource priority and restriction management module 222 and the platform freezing management module 224 through the provided binder interface. The process memory recycling module 234 is used to implement a deep process freezing mode, so that when a third-party application is in a frozen state for a long time, a file area of a process is mainly released, thereby achieving a memory-saving module and increasing the speed of the application when the application is started next time. The timeout freeze exit module 235 is used to resolve the exception generated by the freeze timeout scenario. Through the above-mentioned architecture, the application freezing method in the embodiments of the present application can be implemented.

In one embodiment, as shown in FIG. 3, an application freezing method is provided for freezing foreground applications of a terminal. The embodiment is described by taking the method applied to the terminal shown in fig. 1 as an example. The application freezing method comprises the following steps:

step 302: when the foreground starts an application, monitoring the currently running foreground application to receive operation information input by a user; the operation information includes an operation mode and an operation time point.

The execution of an Application (APP) is usually represented by the execution of a plurality of related processes. The process involved in the foreground application running is the foreground process, and the process involved in the background application running is the background process. And the application corresponding to the operation page of the application program displayed on the current display interface of the terminal is the foreground application currently running on the terminal. In this embodiment, only the application corresponding to the input focus is the foreground application, or only the application corresponding to the window object located on the top of the window stack of the operating system is the foreground application currently corresponding to the terminal. Determining whether the target application is foreground application, acquiring a window object corresponding to the target application, and judging whether the window object is positioned at the stack top of a window stack of an operating system, wherein if the window object is positioned at the stack top of the window stack of the operating system, the target application is the foreground application, and if the window object is not positioned at the stack top of the window stack of the operating system, the application program runs in the background and is background application.

When the foreground application is started, the foreground application can monitor the operation information input by the user. The operation information includes an operation mode and an operation time point input by the user. The operation modes at least comprise input operation modes such as key pressing, voice, touch, fingerprint and scanning. Meanwhile, when the operation information input by the user is received, the currently input operation time point is also acquired. For example, when the application opened by the foreground is "royal glory", it monitors that the user receives all input information of the user when using the foreground application, such as inputs of different operation modes, e.g., voice, touch, etc., and at the same time, records the input time point corresponding to the current input mode, e.g., voice input-20: 00: 00; touch input-20: 00:01, etc.

Step 304: and calling the mapping relation between the operation mode of each application for receiving user input and the freezing condition, and determining whether the foreground application needs to be frozen at the current moment according to the operation information.

When the application runs in the foreground, the application can be regarded as the foreground application, each foreground application running in the foreground corresponds to one or more freezing conditions, and the corresponding freezing conditions can be determined according to the operation mode of receiving the user input. For example, the freezing condition corresponding to the touch operation mode is a first freezing condition, the freezing condition corresponding to the voice operation mode is a second freezing condition, the freezing condition corresponding to the scan operation mode is a third freezing condition, and so on. That is, each mode of operation for each application may correspond to a freeze condition.

Further, the freezing condition is a time condition, and a time freezing condition corresponding to each operation mode may be set, where the time freezing condition may be understood as that the time freezing condition is satisfied when a certain operation information is not monitored within a preset time period.

It should be noted that the operation modes of each application are different, and the freezing conditions corresponding to the same operation mode of different applications may be the same or different.

And according to the preset mapping relation, judging whether the foreground application needs to be frozen at the current moment according to the monitored operation information.

Step 306: and when the foreground application needs to be frozen, freezing the foreground application according to a preset strategy.

When the foreground application needs to be frozen, the foreground application is frozen according to a preset strategy, for example, the corresponding freezing strategy can be set according to the monitored operation information to realize the freezing operation of the foreground application. For example, different freezing levels may be set according to the acquired operation information, and freezing of foreground applications may be implemented according to the freezing levels.

According to the method for freezing the application, when the foreground starts the application, the currently running foreground application is monitored to receive the operation information input by the user, and whether the foreground application needs to be frozen at the current moment can be determined according to the operation information and the preset mapping relation; when the foreground application needs to be frozen, the foreground application is frozen according to a preset strategy, whether the foreground application is frozen or not can be decided according to the operation information input by the foreground application receiving user, namely, the utilization rate of the foreground application by the current user can be acquired through the operation information, when the user does not input the operation information for a long time, the foreground application can be frozen in time, and the intelligence of the terminal is improved.

In one embodiment, as shown in fig. 4, before the mapping of the received operation mode and the freeze condition of each application is invoked, the mapping needs to be constructed.

Before calling the mapping relation between the operation mode of each application for receiving the user input and the freezing condition, the method comprises the following steps:

step 402: and acquiring the historical running time of each application running in the foreground each time and receiving the historical operation record input by the user.

The terminal can acquire the received operation information input by the user when each application runs in the foreground, and count the historical running time of each application running in the foreground each time and receive the historical operation record input by the user. The historical running time is the continuous running time of the application in the foreground; the historical operation record comprises historical operation modes and use frequencies corresponding to the operation modes. The historical operation modes at least comprise operation modes such as key pressing, voice, touch, fingerprint, scanning and the like, and the use frequency corresponding to the operation modes is the use frequency of each operation mode.

When the front desk runs the game Application (APP) of 'Rong Queen' game, the terminal records a starting time point of starting or switching from the background to the foreground to run the 'Rong Queen' game and an ending time point of ending or switching to the background, and the time length between the starting time point and the ending time point is historical running time length, such as 40 minutes. And receiving input operation modes of the user in the historical running time period, wherein the input operation modes comprise voice input and touch input. According to the input operation mode, the use frequency of each operation mode can be acquired, wherein the use frequency of the touch operation mode is 120 times/minute, and the voice operation mode is 2 times/minute.

When the foreground runs the Application (APP) of the player such as the "OPPO video player", the terminal records a starting time point for starting or switching from the background to the foreground running the "OPPO video player", and an ending time point for ending or switching to the background, and the time length between the starting time point and the ending time point is the historical running time length, such as 120 minutes. In the historical operating time length, the input operation modes of the receiving user comprise operation modes such as touch input and sliding input. According to the input operation mode, the use frequency of each operation mode can be acquired, wherein the use frequency of the touch input operation mode is 2 times/60 minutes, and the use frequency of the slide input operation mode is 6 times/60 minutes.

Step 404: and setting the freezing condition of each foreground application according to the historical running time and the use frequency corresponding to the operation mode. Wherein the freezing condition is a time condition.

The historical running time of each application running in the foreground is different, the operation modes of the application for receiving user input may also be different, and the corresponding freezing condition can be set for each application. For example, if a game application APP "royal glory" running in the foreground is divided according to a received operation mode, when the royal glory is in the foreground application, if a touch operation is not monitored within a first preset time period, the first freezing condition is satisfied; the first preset duration is related to the use frequency in the historical operation record, and when the first preset duration is greater than a preset multiple of the use frequency (120 times/minute) of the touch operation mode, the touch operation mode can be determined not to be generated within the first preset duration, and the user can be determined not to use the currently running foreground application.

And when the royal is in the foreground application, if the voice operation is not monitored within a second preset time length, the second freezing condition is met, and the like. The second preset time length is related to the use frequency in the historical operation record, and when the second preset time length is larger than the preset multiple of the use frequency (2 times/1 minute) of the voice operation mode, the voice operation mode can be determined not to be generated within the second preset time length, which indicates that the user is determined not to use the currently running foreground application.

It should be noted that the first preset time period and the second preset time period may be set according to the requirement of the user, and are not further limited again.

Step 406: and constructing the mapping relation between the operation mode of each foreground application and the freezing condition.

And setting the freezing condition of each foreground application according to the historical running time and the use frequency corresponding to the operation mode. Each application corresponds to one or more operation modes, each operation mode corresponds to one freezing condition, that is, one application can correspond to multiple freezing conditions. The mapping relation of the application which can correspond to various freezing conditions is represented by a graph so as to identify the application.

Furthermore, the operation modes of the user input which can be monitored by each foreground application have diversity, the freezing condition of the application can be set according to the input mode which is most frequently used by the user, and the freezing conditions corresponding to other operation modes are ignored.

The priority of the freeze condition may be set according to the frequency of use of the operation modes, and the freeze condition corresponding to the operation mode with a higher frequency of use by the user may be a priority condition for freezing the application. That is, whether the foreground application is frozen or not can be judged according to the priority of the freezing condition corresponding to the operation mode.

In an embodiment, as shown in fig. 5, the determining whether the foreground application needs to be frozen at the current time according to the mapping relationship includes:

step 502: and acquiring the operation information closest to the current moment, and recording the time interval of the closest operation information from the current moment.

When the foreground application is started, the foreground application monitors operation information input by a user, wherein the operation modes at least comprise input operation modes such as key pressing, voice, touch, fingerprint and scanning. Meanwhile, when the operation information input by the user is received, the currently input operation time point is also acquired.

The latest operation information may be the operation information corresponding to the operation time point with the shortest time interval from the current time among all the operation information input by the receiving user from the foreground application starting at this time.

If the current time is 20:30:00 at night, the front desk of the terminal is running 'the royal glory', the user can operate the game in the process of using 'the royal glory', and the terminal can monitor the operation information input by the user in real time. At the current time (20:30:00), the terminal acquires the operation information (operation mode and operation time point) which is monitored at the last time from the current time (20:30:00), and if the operation mode in the latest operation information is the touch operation mode and the operation time point is 20:20:00, the time interval from the current time can be acquired, and the time interval is 10 minutes.

Step 504: and determining whether the time interval meets the freezing condition or not according to the mapping relation.

The set mapping relationship is called to obtain the freezing conditions corresponding to all the operation modes of the application, as described above, the freezing conditions are time conditions, and it can be known whether the obtained time interval meets the freezing conditions for freezing the foreground application according to the mapping relationship.

Step 506: and when the freezing condition is met, detecting whether a human face image exists in the visible area through the terminal.

According to the set mapping relation, when the time interval meets the freezing condition, the situation that the user does not operate the foreground application at the moment can be determined, and whether the user exists in front of the current terminal can be judged by detecting whether the face image exists in the visible area of the current terminal through the terminal. The visible area may be an area where the user can normally use the terminal, or may be a distance between the user and the terminal, where the distance is a comfortable distance for the user to use the terminal.

Specifically, whether a person exists in front of the terminal can be detected through a face recognition technology. Face recognition is a biometric technology for identity recognition based on facial feature information of a person. The method includes the steps of collecting images or video streams containing face images by a camera or a camera (front camera), automatically detecting and tracking the face images in the images, and further performing a series of related technologies of faces on the detected face images, wherein the related technologies are generally called face recognition and face recognition. Through terminal processing, if a face image is identified, the user is indicated to be watching the display area of the terminal, and the user does not operate the terminal; and if the face image does not exist, the fact that the current user is far away from the terminal is indicated, and the foreground application needs to be frozen. That is, step 508: and when the face image does not exist, the foreground application needs to be frozen.

When the face image does not exist, the current user is far away from the terminal, and the currently running foreground application can be frozen, so that the power consumption is saved.

Further, in an embodiment, as shown in fig. 6, determining whether the foreground application needs to be frozen according to the category information of the foreground application further includes:

step 602: and when the face image exists, acquiring the age characteristic of the current face image through a face recognition technology.

When the face image exists, the fact that the user is watching the display area of the terminal is indicated, the user does not operate the terminal, and the age feature of the face image can be recognized based on a deep learning face recognition and age synthesis combined model construction method. The method comprises the steps of carrying out alignment and unsupervised/supervised learning dimensionality reduction preprocessing on a face image acquired by a camera, obtaining features used for identity representation and feature groups represented by different age groups through an automatic encoder obtained through training, outputting image similarity through parallel convolution neural networks on the results of the feature groups, and obtaining a matching result through weighted fusion.

Step 604: and acquiring the application information of the foreground application.

And acquiring application information applied by the foreground, wherein the application information comprises an application network identifier and an application type. Wherein, the application network identification comprises a mobile cellular network identification and a wireless network identification. The application types can be divided into an intelligence development type, a game type, a video and audio type, an instant messaging type, a system tool type and the like according to the functional division of each application; the network division can be divided into a networking class and a non-networking class according to whether each application needs to use the network, wherein the networking class applications comprise communication applications, mailboxes, browsers, dialers, short message services and the like.

Step 606: and determining whether the foreground application needs to be frozen or not according to the application information based on the corresponding relation between the age characteristics and the exclusive application.

The users may be divided into a plurality of user groups according to age characteristics, such as an elderly user group, a middle-aged user group, a young user group, and a children user group. The exclusive application can be formulated respectively for the old user group and the children user group.

And the corresponding exclusive application of the old user group is the application which can only run under the WIFI connection state. According to the application information of the foreground application, whether the foreground application can be operated only in a WIFI connection state can be determined, if not, the foreground application needs to be operated by the mobile cellular network, and the foreground application is considered to be frozen, so that a large amount of data traffic caused by misoperation is prevented.

The corresponding exclusive application of the child user group is the intelligence development application. According to the application information of the foreground application, whether the foreground application is the intelligence-developing application or not can be determined, if not, the foreground application is the game application or the video application except the intelligence-developing application, the foreground application is considered to be required to be frozen, and the probability that the student user is addicted to the game is reduced.

In one embodiment, as shown in fig. 7, the freezing the foreground application according to the preset policy includes:

step 702: and when the time interval meets the freezing condition, acquiring the duration of the time interval.

And acquiring the operation information closest to the current moment, and recording the time interval of the closest operation information from the current moment. And the latest operation information is the operation information corresponding to the operation time point with the shortest time interval with the current time in all the operation information input by the receiving user from the current starting of the foreground application. When the acquired time interval satisfies the freezing condition, the duration of the time interval is acquired.

Step 704: dividing freezing grades according to the duration; the freeze level is used to indicate a maximum allowed resource that can be used to configure the foreground application.

And dividing freezing grades according to the duration of the acquired time interval. Wherein the freeze level is used to indicate a maximum allowed resource that can be used by the configuration foreground application. The resource that can be used represents the resource that can be used by the process at each time when the process is executed. The maximum allowed resource represents the maximum resource that a process is allowed to use at each time. The longer the interval, the higher its freeze level, and the higher its freeze level, the less maximum allowed resources that can be used by its foreground applications.

The terminal has a plurality of processes in a running state, and a process (process) is a running activity of a program in a computer on a certain data set, is a basic unit for resource allocation and scheduling of a system, and is the basis of an operating system structure. The process involved in the foreground application running is the foreground process, and the process involved in the background application running is the background process.

In an operating system, the interaction mechanism between processes is mainly divided into a synchronization mechanism and a communication mechanism. The communication mechanism includes socket, binder, shared memory, etc. Two programs on the network effect the exchange of data via a bidirectional communication link, one end of which is called a socket. Binder is an inter-process communication mechanism that provides remote procedure call functionality.

The terminal can acquire the foreground process according to a preset frequency or according to a detected user operation instruction. Optionally, a process identifier of the foreground process may be obtained, where the process identifier is used to uniquely identify a corresponding process, and may be formed by one or a combination of several of numbers, letters, or other characters with preset digits. For example, process A can be represented by process identification "0001", process B by "1234", and so on.

It should be noted that the freezing level may be set according to the requirement of the user, and may be set by combining the historical running time of the foreground application and the application type of the foreground application. The freezing levels applied by each application may be the same or different, and the number of the freezing levels may be the same or different.

Step 706: and freezing the foreground application at a corresponding level according to the freezing level.

And determining the freezing grade corresponding to the current time interval according to the duration of the time interval. If the memory required by the current station process is 40Mb, if the freezing level is the first level (lowest level), allocating resources to the foreground according to the first freezing level, and the maximum allowed resource which can be used by the foreground application is 30 Mb; and if the freezing level is four levels (the highest level), allocating resources to the foreground according to the one-level freezing level, wherein the maximum allowed resource which can be used by the foreground application is 0 Mb. Wherein the highest level of freezing is a completely frozen state.

The resources may include a CPU, I/O file resources, and the like. Taking resources as a memory for example, the longer the interval time is, the higher the freezing level is; the higher the freeze level, the less maximum allowed resources that can be used by its foreground application.

In the method, the freezing level is set according to the duration of the time interval, the freezing level is increased along with the increase of the duration, but the maximum allowed resource which can be used by the foreground application is reduced along with the increase of the duration until the foreground application is in a complete freezing state. A certain time process is needed from partial freezing to complete freezing, a buffering time period is given to a user, and in the time period, the user can quickly and effectively unfreeze the foreground application, so that the user experience is improved. Meanwhile, the maximum allowed resource which can be used by foreground application is limited according to the freezing grade, the resource can be reasonably distributed, and the power consumption is reduced.

In one embodiment, as shown in fig. 8, the freezing the foreground application according to the preset policy includes:

step 802: and acquiring all functions of the foreground application and the functions corresponding to the operation modes monitored by the current foreground application.

The foreground application has various functions, and when the freezing condition is met, the function corresponding to the operation mode monitored by the current foreground application is obtained. One mode of operation may correspond to one or more functions, for example, a voice operation may correspond to functions of voice communication, voice control, voice search, etc., and a scan operation may correspond to functions of scan recognition, scan payment, scan authentication, etc. By acquiring the monitored operation mode, the function corresponding to the monitored operation mode can be acquired correspondingly.

It should be noted that the functional functions corresponding to the operation modes may further include, but are not limited to: recording, taking pictures, connecting with a network, using Bluetooth, acquiring geographic positions, making calls and sending short messages.

Step 804: and acquiring unused functions according to the functions corresponding to the monitored operation modes.

When a user uses a current foreground application, there is generally a function that the user does not use frequently. The unused function refers to a function other than the function corresponding to the monitored operation mode among all the functions of the foreground application.

For example, the game application of 'royal glory' of the terminal is taken, and the 'royal glory' comprises a plurality of functions, such as a competition function, a transaction function and a geographical position acquisition function corresponding to touch operation; performing voice instant messaging function corresponding to voice operation; a record and photograph function, etc. When the time interval meets the freezing condition, the functions corresponding to the operation modes monitored by the foreground application are mainly a competition function and a voice instant communication function, and the unused functions comprise a transaction function, a geographic position acquisition function, a recording and photographing function and the like.

Step 806: and freezing the corresponding process of the unused function in the system.

Each application corresponds to a process group in a system frame, and when the application is operated, the system can allocate resources to the corresponding process group; each function module in the application also corresponds to the process in the process group, so that the corresponding process of each function of the application is identified, and the subsequent system resource allocation management of the corresponding process is facilitated. The identifier is used for uniquely identifying the corresponding process and can be formed by one or a combination of several of numbers, letters or other characters with preset digits. For example, process A can be represented by process identification "0001", process B by "1234", and so on

Taking the game application of 'royal glory' of the terminal as an example, when the front desk runs 'royal glory', the unused function can be obtained according to the function corresponding to the monitored operation mode. Among them, unused functions (transaction function, geographical position acquisition function, recording and photographing function, etc.). But unused functions will also run in the background, occupying system resources.

By the method, the user can freeze the corresponding process of the unused function in the system, and the purposes of saving resources and improving the operation efficiency are achieved. But other functions of the foreground application can still be used, so that the whole application is not required to be frozen, but partial functions of the application are frozen, and normal use of other partial functions is ensured, thereby achieving the effect of reducing power consumption.

In one embodiment, as shown in fig. 9, applying the freezing method further comprises:

step 902: and acquiring a unfreezing instruction for unfreezing the foreground application.

Step 904: and detecting whether the biological characteristic information in the unfreezing instruction is matched with a preset biological characteristic.

Step 906: and when the biological characteristic information in the unfreezing instruction is matched with the preset biological characteristic, unfreezing the foreground application.

That is, when the foreground application needs to be thawed after being frozen, the thawing instruction input by the user needs to be obtained. Biometric information is included in the thawing instruction, wherein the biometric information may be fingerprint information, iris information, voiceprint information, facial information, and the like.

It should be noted that different applications may set different biometric information, or may set the same biometric information, and the biometric information may be set by user-defined settings according to the needs of the user.

And when the biological characteristic information in the unfreezing instruction is matched with the preset biological characteristic information, unfreezing the foreground application. During the unfreezing operation, a corresponding unfreezing strategy can be set according to the freezing strategy, so that the unfreezing operation applied to the foreground is realized.

and a freezing module 1030, configured to freeze the foreground application according to a preset policy when the foreground application needs to be frozen.

In the application freezing device, when the foreground starts an application, the monitoring module 1010 can monitor the currently running foreground application to receive operation information input by a user; the determining module 1020 may invoke a mapping relationship between an operation mode of each foreground application and a freezing condition, and determine whether the foreground application needs to be frozen at the current time according to the mapping relationship; when the foreground application needs to be frozen, the freezing module 1030 freezes the foreground application according to a preset strategy, can acquire the utilization rate of the current user on the foreground application through the operation information, and can freeze the foreground application in time when the user does not input the operation information for a long time, so that the intelligence of the terminal is improved.
