- Abstract:
-
Considering the low evolution speed and the tendency towards stagnation of ant colony optimization (ACO), an improved ACO was discussed based on an adaptive pheromone evaporation factor. To avoid the defect of ACO easily falling into the local optimum, another improved ACO was proposed based on Gaussian variation of decision variables. To overcome the shortcoming of the slow speed of ACO, a new and improved ACO was given based on boundary selftuning of the decision variables. Finally, an improved hybrid ant colony algorithm was proposed, which combined the adaptive pheromone evaporation factor, Gaussian variation of decision variables, and boundary selftuning of the decision variables. When applied to function optimization, the simulation results show that the improved hybrid ACO has a higher degree of accuracy, a higher convergence ratio, and improved optimization performance.
