Abstract:

In view of the overcome the problem of the slow convergence speed and low precision of ant colony algorithm in solving TSP(Traveling Salesman Problem), a heterogeneous ant optimization based on dynamic entropy evolution is proposed. In this algorithm, a heterogeneous double population is comprised of ACS(Ant Colony System) and MMAS(Max-Min Ant System),which is helpful to promote the complementary advantages between the populations. And the dynamic entropy evolution strategy is introduced to dynamically control the communication frequency between the populations by information entropy. The pheromones of the two populations' optimal common paths are fused to adjust the distribution of pheromones on the optimal paths of the low entropy populations, thereby effectively preserving the historical search information of the two populations and accelerating the convergence of the algorithm.The non-common path of the optimal solution of low entropy population is pseudo-initialized to expand its search range near the optimal solution and improve the accuracy of the solution, so as to realize the co-evolution of two populations.Simulation results show that the proposed algorithm can effectively balance the relationship between algorithm diversity and convergence when solving large-scale traveling salesman problems.

Key words: ant colony optimization, heterogeneous colony, diversity, dynamic entropy, coevolution, pheromone fusion, pseudo initialization, traveling salesman problem
