| 中文摘要: |
| 智能计算方法在大型空间智能桁架结构的主动杆优化配置问题中有着广泛的应用。为有效避免传统遗传算法编码方式在算法实现过程中容易出现无效染色体的问题,本文基于字典序整数编号的遗传算法,给出了一个由整数编号还原到对应组合的快速还原算法。利用此方法对空间T型桁架结构的主动杆位置优化进行仿真并与传统编码方法结果进行比较,验证了本文方法的有效性和优越性。 |
| 英文摘要: |
| The intelligent computation methods are currently extensively used in the placement optimization of driving levers for large space truss structures. To overcome the shortcomings of the genetic algorithm with regular coding method which often leads to the repetitive or invalid solution,a fast decoding algorithm is proposed to aid in the application of the lexicographic-order integer-coded genetic algorithm to driving lever placement optimization problems. A large T-shape truss structure is taken as an example to illustrate the effectiveness and efficiency of the method through some comparison with the genetic algorithm based on the traditional coding. |
