Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings, and the described embodiments are only some of the embodiments of the present invention, not all of them.
[0027] refer to figure 1 , an efficient particle swarm optimization method (Surrogate-based EfficientPartical Swarm Optimization, referred to as SEPSO) based on the RBF (Radial Basis Function) proxy model, including the following steps:
[0028] Step 1, initialize the population, perform Latin hypercube sampling in the search space to generate NP individuals as the initial population P 0 =(x 1,0 ,x 2,0 ,...,x NP,0 ), while initializing the initial velocity V of the individual 0 =(v 1,0 ,v 2,0 ,...,v NP,0 ), the number of iterations g=0, the number of function evaluations FES=0 Use the true fitness evaluation function f( ) to evaluate the population P 0 , adding it to the sample data set Data, the number of function evaluations FES=FES+NP;
[0029] Step 2, ...
