摘要
针对基本简单遗传算法中的交叉、变异概率均是恒定不变的参数的局限性,提出了可变概率的交叉、变异算子的针对离散变量结构优化设计的自适应遗传算法。以平面和空间桁架为算例,并将计算结果与其他算法所得结果进行比较,结果表明,这种算法对离散变量的桁架截面优化设计是有效可行的。
Because of the simple GA's shortcomings,that are,crossover probability and mutation probability keep constant.Adaptive crossover probability and mutation probability in the research of GA for discrete variables optimization design is presented in this paper.The optimal results are compared with other method by examples on optimum design for plane and space truss structure.The results indicate that the AGA are effective and feasible to optimization design of truss structure.
