文摘A new evolutionary algorithm for constrained optimization problem is proposed in this study.In the algorithm,search space was gradually constracted to optimal solution while evolutionary algorithm was used repeatedly and incompletely,until the space constracted small enough. Then evolutionary algorithm ran fully. Real coding was used,and only crossover operators were adopted but two kinds of crossover operators were used in the new algorithm. The computation results dimonstrated that the new algorithm is superior to other methods in terms of solution quality, robustness and convergent speed.
