Over the last few years, ant algorithm has come out and gradually got much attention.This algorithm, which is stochastic and all purpose, simulates the characteristics of action ants searching for food in nature. When working, a mobile robotis required to walk along an optimized (or approximately optimized) route according to a certain rule.By maklink graph, the moving space of Robot is described.Using Ford algorithm,a preliminary route is gained.Then, exerting Ant algorithm, we optimize the preliminaryroute and acquiresatisfactory effect.
