Example 1: referring to fig. 1, the flexible configuration method for scale elements based on visual simulation scoring according to the present embodiment includes the following steps:
S1: randomly generating a set of initial scale element configurations, generating a configuration set based on the initial scale element configurations, specifically:
determining parameters and variables of the scale element configuration, which may include the size, shape, material, scale type, etc. of the scale, defining a reasonable range for each configuration parameter, e.g. the length of the scale may vary within a certain range, the density of the scale may vary within another range, randomly generating a set of initial parameter values within the determined parameter range, which will create an initial scale element configuration;
determining the size of a configuration set to be generated, which may be a predetermined fixed number or a number dynamically adjusted according to algorithm requirements, and outputting a final configuration set, wherein the final configuration set comprises a plurality of scale element configurations which are randomly generated;
to better illustrate how an initial set of scale element configurations may be randomly generated, examples are as follows:
let us assume that we want to design a scale element, the parameters including the length, shape, material and scale type of the scale;
parameter and variable definitions:
scale length L: varying over a range of [10,50] cm;
ruler shape S: may be a ruler, a curved ruler, etc., where represented by a binary variable, such as s= {0,1}, where 0 represents the ruler and 1 represents the curved ruler;
Ruler material M: may be plastic, metal, etc., represented here by binary variables, such as m= {0,1}, where 0 represents plastic and 1 represents metal;
scale type T: may be a digital scale, a linear scale, etc., where a binary variable is represented, such as t= {0,1}, where 0 represents a digital scale and 1 represents a linear scale;
parameter range definition:
l epsilon [10,50] cm;
s.epsilon.0, 1 (ruler, curved ruler);
m.epsilon.0, 1 (plastic, metal);
t ε {0,1} (numerical scale, linear scale);
randomly generating initial parameter values:
each parameter is randomly generated within its defined range, for example: randomly generating a value of L, S, M, T;
configuration set size:
a fixed number is predetermined, for example, the selection of 100 different initial scale element configurations;
outputting a final configuration set:
the output comprises a set of randomly generated arrangements of a plurality of scale elements. Each configuration consists of its parameter values forming a specific scale element, for example, to randomly generate one of the following initial configurations:
1) L=30 cm, s=0 (ruler), m=0 (plastic), t=1 (linear scale);
2) L=30 cm, s=0 (curved ruler), m=0 (metal), t=1 (numerical scale);
3) L=30 cm, s=0 (ruler), m=0 (plastic), t=1 (numerical scale);

for each scale element configuration, its score is normalized to a relative value, which can be achieved by dividing the score of each configuration by the highest score of all configurations, specifically:
for each scale element configuration, there is a corresponding score, which may be based on a plurality of metrics, such as visual effect, user experience, etc., traversing the scores of all scale element configurations, finding the highest score, which will be the basis for normalization, dividing its score by the highest score in all configurations, which will generate a relative value representing the relative performance of each configuration on the respective metrics, expressed as: relative score = score of configuration/highest score of all configurations, which ensures that the relative score is between 0 and 1, where 1 represents the highest score and 0 represents the lowest score, the same normalization process is performed for each scale element configuration to obtain the relative score, by comparing the relative scores, the best performing configuration can be identified, which helps to determine which configurations perform better on a particular metric, supporting decision making and improvement.
S4: searching is carried out according to the level of the guide factors and heuristic information, the configuration of the scale element is updated, a local search mechanism is introduced to increase the local optimization capacity of the configuration system, and the method comprises the steps of adopting a local search operator or carrying out a certain range of variation in a search space, and specifically comprises the following steps:
heuristic information is computed for each scale element configuration, which may be additional information about a point in the configuration space, such as gradients, local slopes, etc., used to guide the search, with the scale element configuration being selected in the search space using the steering factors, the higher steering factor configurations being more likely to be selected, thereby increasing their impact in the search.

Initializing a local slope for each scale element configuration, which may be zero, or some initial value according to prior knowledge of the problem and initial configuration settings, calculating the local slope for each scale element configuration based on local slope rules, normalizing the local slopes to ensure consistency in comparison between different local slopes, which may be normalized to a specific range to ensure that their weights are balanced when the guide factor is selected, calculating a composite score for each scale element configuration in combination with the guide factor and normalized local slope, expressed as: z is Z Score of ＝(1-σ)*dz Normalization +σ JBX; wherein Z is Score of The composite score for the scale element configuration, σ is a parameter that balances the normalized guide factor level and the normalized local slope, and has a value between 0 and 1, dz Normalization Is the guide factor after normalizationSub-level JBX is normalized local slope, and according to the composite score, selecting scale element configurations in the search space, scale element configurations of higher composite scores being more likely to be selected;

calculating the current configuration dz of the objective function i A value at, comprising the steps of:
determining a specific target or objective function to be optimized, which may be a complex function, covering various aspects of the scale element configuration, such as visual effect, user experience, scale accuracy, etc., inputting the parameter values of the currently selected scale element configuration into the objective function, including parameters of scale size, shape, texture, etc., depending on the definition of the objective function, performing simulation or calculation: depending on the nature of the objective function, a corresponding simulation, calculation or rendering operation is performed, which may include simulating scale usage, calculating image quality, evaluating scale accuracy, etc. in a virtual environment, resulting in an objective function value: based on the results of the simulation or calculation, the value of the objective function at the current configuration is calculated, which is a quantized representation of the objective function, showing the merits of the objective under the current configuration, and for a better illustration of this scheme we exemplify the following:
Assuming that our goal is to design a virtual scale element in which the objective function covers both visual effects and user experience, we want to minimize the ambiguity of the scale on the scale and maximize the user's satisfaction with the scale, the goals of both aspects can be expressed by the following calculation formula:
setting Clarity as the definition of the scale, wherein the value range is between 0 and 1, 0 represents blurring, 1 represents very clear, and the aim is to maximize definition;
setting the Satisface as the Satisfaction of the user, wherein the value range is between 0 and 1, 0 represents dissatisfaction, 1 represents very Satisfaction, and the aim is to maximize the Satisfaction of the user;
