【摘要】 提出了采用改进的遗传算法进行网架结构截面尺寸优化设计的方法。通过建立优化问题的数学模型、凝聚约束、惩罚不可行个体、选择、交叉和变异,经过若干次迭代寻得网架结构优化设计的最优结果。最后举例说明改进的遗传算法用于网架优化的可行性。更多还原

【Abstract】 It was proposed the method for optimization design of section size of a latticed frame using the modified genetic algorithm.The optimal result was obtained through mathematic model,coagulating restraint,selection and variation etc,as well as by iterations.Finally an example was used to show the feasibility of the modified genetic algorithm to optimize latticed frames.更多还原
