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 摘要結(jié)合復(fù)形法與粒子群算法的優(yōu)點(diǎn),提出粒子群復(fù)形法,用于求解非線性方程組,以克服牛頓法初始點(diǎn)不易選擇的問(wèn)題,同時(shí)克服復(fù)形法與粒子群算法由于易陷入局部極值而導(dǎo)致方程組的解的精度不夠的不足。
