Abstract: A state producer that can produce feasible state is designed.The new state that produced by the state producer can satisfy all the constraints,so the constraints are handled efficiently.And an improved simulated annealing algorithm to solve the truss shape optimal design problem is introduced.The example indicates the method can achieved the better solution,at the same time,the whole optimum of the truss shape optimal problem can’t be obtained by the improved simulated annealing algorithm is pointed out.

摘要: 通过设计一种产生可行解的状态发生器,由该状态发生器产生的新状态均满足所有的约束条件,从而方便地处理约束条件,并提出一种求解桁架形状优化设计问题的改进的模拟退火算法。算例表明该方法能获得较高质量的解,具有现实的工程意义,同时指出改进的SA算法用于桁架形状优化问题得不到全局最优解。
