Improved wolf pack algorithm based on adaptive step length and adjustable scouting direction(基于自适应和变游走方向的改进狼群算法)
针对狼群算法涉及参数较多、步长参数无法动态调整、游走方向固定等缺点,提出了一种基于自适应和变游走方向的改进狼群算法.该算法改进了游走行为、召唤行为、围攻行为3个主要步骤的移动步长,特别是当游走行为的试探方向改进后,每头狼都能根据头狼位置的变化自动调节移动步长、更换游走方向,从而简化参数设定,提高收敛速度和求解精度.仿真结果表明,改进算法在低维单峰函数求解精度上较原算法有明显改善,亦进一步提高了高维多峰函数的求解精度....
