为了解决粒子群优化算法在处理边界约束问题时容易早熟的问题,从理论上证明了传统的不可见墙(In-visib le Wall,IW)方法存在两种缺陷,即邻居中最优粒子与其他粒子具有不均等的进化机会,且大量的位置升级是多余的;并提出了一种改进的IW,...为了解决粒子群优化算法在处理边界约束问题时容易早熟的问题,从理论上证明了传统的不可见墙(In-visib le Wall,IW)方法存在两种缺陷,即邻居中最优粒子与其他粒子具有不均等的进化机会,且大量的位置升级是多余的;并提出了一种改进的IW,即对各维分别进行离界判断,若其离界则立即再次升级。实验证明,改进的IW在收敛精度和运行时间上具有更好的性能,并对不同类型的边界表现了更强的鲁棒性和一致性。展开更多
