SU127048A1 - Auto Optimizer - Google Patents

Description

BASIC Auth. St. No. 123759 described automatic optimizer.

The proposed device differs from the known ones in that o-but has on-definition power supply units whose inputs are connected to the outputs of the optimizer channels, and the outputs using a switch can be connected directly through the inverter, depending on the switch unit of the sign consisting of keys and an indicator of the sign of the function increment, to the common input of the channels. This inclusion of blocks of increments makes it possible to determine the direction of the gradient of the function.

To automate the verification of the extremum truth, an additional block is connected to the control unit, consisting of a switch for two positions, one-shot memory and a disturbance task.

The described device is intended for the automatic verification of the truth of the extremum of a function of n variables having the form of a ridge or saddle, and contains an increment definition block, a program block and logic elements.

The drawing shows an ohlti-ator with a block for determining the direction of the ridge (circled in dashed lines). The latter includes (n + 1} blocks 1 for determining the difference in coordinate values and an oltimizioem: Function. And. The outputs of the blocks / four keys 2 are connected to a common bus, which by means of a switch (switches 3 to 4 operating on the switch) either directly or via an inverter can be connected to the input bus of all channels via the keys 5. The keys 2 are powered from the same triggers of the main register as the keys of the 6 channels.

No. 127048

A switch of two positions is added to the optimizer's control unit, a chain of one-off clutter 7 and disturbance 5 and an indicator of reaching the extremum of block 9 with Yun 11 switch-switched keys.

The operation of the circuit is as follows. While key 10 is closed (“key // open), the usual search process is in progress. Upon reaching the extremum, block 9 will open the key 10 and close the key 11. After the working step through the switch 12, which is in position /, the impulse will excite a chain of one-vibrators 7 and S, and then the trigger 13 in the usual optimizer circuit. The passage of the pulse through the switch 12 overturns it to the position //. When the one-shot 7 is excited, the coordinates of the reached extremum will be memorized by sending commands to all blocks /, and when the one-shot 8 is excited, it will be compensated for the inputs of all the channel integrators. This method moves the 15-point from the ridge. Since the extremum is no longer present, block 9 will switch the keys 10 11 vi, and the usual search process will continue until it reaches another point.

As soon as this point is reached, block 9 will again open the key 10 and close the key 11. In this case, the impulse from block 14 will fall into the position of // switch 12 and overturn the trigger 15, which will close the key 5 and unlock the key 16, i.e. will switch the common channel bus from the output of the block 17 to the bus of the outputs of the blocks. Now, during the definition of the gradient, the inputs of the channels 18 will be connected to the outputs of blocks 1 via the keys 2 & 6 directly or through an inverter. After memorization, trigger 15 is reset. Now, during the working stage, the movement will be made along the line of the ridge and steps;

In the case of a saddle, the same procedure will lead to the determination of the vertex of one of the humps.
