A complex particle swarm optimization ( cpso ) algorithm , which combines the advantages of method of complex ( mc ) and particle swarm optimization ( pso ) , is put forward to solve systems of nonlinear equations , and it can be used to overcome the difficulty in selecting good initial guess for newton ' s method and the inaccuracy of mc and pso due to being easily trapped into local minima for solving systems of nonlinear equations 摘要结合复形法与粒子群算法的优点,提出粒子群复形法,用于求解非线性方程组,以克服牛顿法初始点不易选择的问题,同时克服复形法与粒子群算法由于易陷入局部极值而导致方程组的解的精度不够的不足。
