一种新型非线性收敛因子的灰狼优化算法
Novel grey wolf optimization algorithm based on nonlinear convergence factor
摘要
Abstract
The classical grey wolf optimization (GWO)algorithm has a few disadvantages of low solving precision and high possibility of being trapped in local optimum.This paper proposed a novel grey wolf optimization (NGWO)algorithm for sol-ving unconstrained optimization problems.The proposed algorithm used opposition-based learning strategy to initiate popula-tion,which strengthened the diversity of global searching.Inspired by particle swarm optimization (PSO),this paper proposed an improved convergence factor update equation,which was based on that the values of parameter a are nonlinearly decreased over the course of iterations.The convergence factor was dynamically adjusted to maintain a better balance between global search and local search.Mutation operator was given on the current optimal individual of each generation,thus it could effec-tively jump out of local minima.Experiments are conducted on a set of 10 unconstrained benchmark functions.Based on the results,the proposed NGWO algorithm shows significantly better performance than the standard GWO algorithm.关键词
