| Abstract: | In order to improve the problems of real-coding based genetic algorithm(RGA),such as premature convergence,rough result and low speed of calculation,the model structure of multi-population genetic algorithm(RMGA) is analyzed,and the parallel characteristics of this algorithm is applied to the roundness error evaluation.Experiments show that this algorithm can improve the accuracy and convergence in assessment of roundness error effectively. |
