| 摘 要： | 普通遗传算法经常出现易早熟、随机性较大、收敛速度较慢等问题,基于Sigmoid函数,提出了一种新的改进的自适应遗传算法.该算法可以有效提高收敛速度并防止算法陷入局部最优解,通过算例分析,证明了该方法的可行性和有效性.结果表明,提出的新型遗传算法可以为其在大型土木建筑结构的优化设计中的推广应用提供理论支持.

| Abstract: | Common genetic algorithm had some disadvantages,such as premature convergence,greater randomness and slower convergence speed.A new improved adaptive genetic algorithm was proposed based on the Sigmoid function,and it effectively improved the convergence speed of the algorithm and avoided falling into local optimal solution.The feasibility and effectiveness of the method were proved by an example of a cantilever truss.This new genetic algorithm could provide theoretical support for its popularization and application in the structural optimization design of large civil engineering. |
