- Abstract:
-
An improved ant colony algorithm is proposed in this paper. Firstly, in order to overcome the demerits of the ant colony algorithm, such as low convergence speed and easy to get into the local optimum, α and β are dynamically adaptively adjusted by establishing an interlock between alpha (pheromone heuristic factor) and beta (expected heuristic factor) in the searching route process of ant colony. Secondly, in order to prevent the ant colony algorithm from falling into deadlock when facing concave obstacles, which decreases search efficiency, an update rule of the generalized pheromone is proposed. Finally, static modeling for a known environment is conducted by the grid method. The simulation experiments showed that with different scales of TSP, the improved ant colony algorithm is feasible and efficient. In addition, this algorithm is applied to the obstacle avoidance of robots and the results are effective.
