桁架结构拓扑优化与遗传算法

Topological optimization of truss structure via the genetic algorithm

用遗传算法求解桁架结构拓扑优化，结果表明是可行的。

Topological optimization is one of the most difficult problem in structural design,whichcan't be dealed with efficiently so far.Main obstacle of topological optimization is the sigu-larity of design spaces caused by the constraints deletion at some points. The genetic algo-rithm (GA)is a search procedure abstracted from natural genetics & natural selection,whose three basic operators are reproduction,crossover & mutation. The paper tries to solvethe topological optimization using the GA,which is showed to be feasible by the results ofgiven examples.
