| Abstract: | This paper represents a method for solving systems of nonlinear equations.Firstly,we transform them into numeric problems of least square approximation.Then,we give some operators of selection,crossover and mutation;we also give strategies of the best individual reservation for convergence speedup,and operators of depopulation and emigration for preventing prematurity.By applying real code genetic algorithm we solved the problem.The results of numerical simulation show the efficiency of the method. |
