摘　　要：在多目标快速群搜索算法(MQGSO)的基础上,针对该缺点进行了约束处理方面的改进,引入了过渡可行域,提出了改进的多目标快速群搜索算法。改进后的算法,充分利用了过渡可行域中不可行解的价值。通过一10杆平面桁架的截面优化,对改进后的算法进行了优化性能测试。与MQGSO对比,改进后的算法收敛速度和收敛精度更优,解集的分布也更加均匀,可以应用于实际工程的优化设计中。The improved multi-objective quick group search optimizer, which is based on multi-objective quick group search optimizer,poses the idea of transition-feasible region. It makes full use of the value of infeasible solutions in the feasible region. The optimization result of the improved MQGSO algorithm was compared with the MQGSO algorithm by an example of a 10-bar planar truss structure. The improved MQGSO algorithm gets preferable convergence rate convergence precision and wide distribution. The improved multi-objective quick group search optimizer can be used for practical structural optimal design problems.
