To overcome the defects of precocity and the time for initial population building is too long in traditional augment ant colony algorithm for mobile robot global path planning, an improved augment ant colony algorithm is presented in this paper. The operations of crossover and mutation of genetic algorithm (GA) are used in augment ant colony optimization, and the heuristic probability function is added to the process of the initial population building. The process flow of improved ant colony algorithm is given and the simulation experiment is done under the VC++ 6.0 environment. Experimental results show that the algorithm has much higher capacity of global optimization than traditional augment ant colony algorithm.
