摘　　要：针对黑猩猩优化算法(Chimp optimization algorithm,ChOA)存在收敛速度慢、精度低和易陷入局部最优值问题,提出一种融合多策略的黄金正弦黑猩猩优化算法(Multi-strategy golden sine chimp optimization algorithm,IChOA).引入Halton序列初始化种群,提高初始化种群的多样性,加快算法收敛,提高收敛精度;考虑到收敛因子和权重因子对于平衡算法勘探和开发能力的重要作用,引入改进的非线性收敛因子和自适应权重因子,平衡算法的搜索能力;结合黄金正弦算法相关思想,更新个体位置,提高算法对局部极值的处理能力.通过对23个基准测试函数的寻优对比分析和Wilcoxon秩和统计检验以及部分CEC2014测试函数寻优结果对比可知,改进的算法具有更好的鲁棒性;最后,通过2个实际工程优化问题的实验对比分析,进一步验证了IChOA在处理现实优化问题上的优越性.Chimp optimization algorithm(ChOA)has the problems of slow convergence speed,low accuracy and easy to fall into local optimal value.A multi-strategy golden sine chimp optimization algorithm(IChOA)was proposed.The Halton sequence is introduced into the algorithm to initialize the population,which improves the diversity of the initialized population,accelerates the convergence of the algorithm,and improves the convergence accuracy.Considering the important role of convergence factor and weight factor on the exploration and exploitation of the balance algorithm,the improved nonlinear convergence factor and adaptive weighting factor are introduced to balance the search ability of the algorithm.The golden sine algorithm is used to update the individual position and improve the ability of the algorithm to deal with the local extreme value.Through comparative analysis of the optimization of 23 benchmark test functions,Wilcoxon rank sum statistical test and optimization results of some CEC2014 test functions,it can be seen that the improved algorithm has better robustness.Finally,through comparative analysis of two practical engineering optimization problems,the superiority of IChOA in dealing with realistic optimization problem is further verified.
