PIO算法的matlab程序，用于路径自动规划-Inspired by the above homing behaviors of pigeons, a novel bio-inspired swarm intelligence optimizer which is named PIO has been invented in 2014 . In order to idealize some of the homing characteristics of pigeons, two operators

are designed by using some rules, map and compass operator model is presented based on magnetic field and sun, while

landmark operator model is designed　based on landmarks.
