In order to solve the problem of genetic algorithm's premature convergence,CIO was put forward firstly.Because of the properties of ergodicity and inherent stochastic property of chaos iteration,CIO can overcome the problem of propagation in close relative and ensures that the genetic algorithm converges to global optimization.The program of chaos genetic algorithm (ChGA1.0) had been designed with MATLAB language.Design examples show that this algorithm has better global convergence than simple genetic algorithm and has robustness.This optimal algorithm can be used to solve optimal design problems with constraints or no constraints,and then has engineering practical value.
