Abstract

The invention provides a function optimization method, device and system. The method comprises the steps of determining a target function and a decision variable corresponding to an actual applicationscene; based on the target function and the decision variable corresponding to the actual application scene, constructing a system model of a matched bacterial chemotaxis function optimization algorithm; executing a function optimization operation on the system model of the bacterial chemotaxis function optimization algorithm to obtain a decision variable optimal solution for optimizing the target function, wherein the moving step length of the decision variable in the function optimization operation is in a decreasing trend along with the increase of the number of iterations; and outputtingthe optimal solution of the decision variable for an actual application scene. The invention provides a scheme for realizing the trend of the moving step length from large to small in the function optimization process of the bacterial chemotaxis function optimization algorithm, so that the convergence and the optimization rate of the bacterial chemotaxis function optimization algorithm are improved. In addition, a directed mutation strategy is provided for the system model of the multi-target bacterial population chemotaxis algorithm to improve the distribution of bacterial populations.

Description

technical field [0001] The invention relates to the technical field of automatic decision-making, in particular to a function optimization method, device and system. Background technique [0002] Among the many function optimization algorithms, many are inspired by natural biological processes. For example, the bacterial chemotaxis function optimization algorithm is derived from the movement behavior of bacteria towards attractants. According to the number of objective functions and the number of bacteria in the decision space, the bacterial chemotaxis function optimization algorithm can be divided into: [0003] A bacterial chemotaxis algorithm using a single bacterium to optimize a single objective function, a bacterial swarm chemotaxis algorithm using a bacterial swarm to optimize a single objective function, and, a multi-objective bacterium using a bacterial swarm to optimize multiple objective functions Population chemotaxis algorithm. The optimization speed of the ba...
