说明：  目前,粒子群算法在连续问题优化上的应用已经很广泛,然而在离散问题优化方面仍处在尝试阶段,提出了一种改 进粒子群算法来解决矩
(At present, particle swarm optimization (PSO) has been widely used in continuous problem optimization, but it is still in the trial stage in discrete problem optimization. A modified particle swarm optimization algorithm is proposed to solve the moment problem.)
