- Abstract:
-
To solve the problems of slow convergence speed and easily falling into local optimization, a novel improved ant colony algorithm is proposed based on a group teaching optimal algorithm (GTACO). The improved ant colony algorithm is optimized in three aspects. Firstly, the group teaching optimization algorithm is used to improve the fitness function of the ant colony algorithm to enhance the searching ability of global solutions. Simultaneously, a new fallback strategy is designed to deal with the U-shaped deadlock and ensure the feasibility of the solution. Secondly, a novel updating strategy for dynamic pheromones is adopted to avoid falling into local optimization of the algorithm by updating the path pheromone value after each iteration. Finally, the simplification operator of the path is applied to shorten the length of the path by simplifying the redundant corners into linear paths. Simulation experiments show that the improved algorithm can effectively increase the ability of path planning in convergence speed and accuracy for mobile robots.
