用对数函数描述收敛因子的改进灰狼优化算法及其应用
Improved grey wolf optimization algorithm with logarithm function describing convergence factor and its application
摘要
Abstract
The grey wolf optimization (GWO) algorithm has a few disadvantages such as low precision and high possibility of being trapped in local optimum, an improved GWO algorithm was proposed for solving high-dimensional optimization problem based on the convergence factor about logarithmic function. An initial population was generated based on good point set method to assure that the individuals were distributed in the search space as uniformly as possible. A nonlinear convergence factor was proposed based on logarithm function to balance the exploration ability and exploitation ability. Improved elite opposition-based learning strategy was used to avoid premature convergence of GWO algorithm. Benchmark functions and parameters optimization of real application were employed to verify the performance of the improved GWO algorithm. The results show that the proposed algorithm has better performance.关键词
