A Modified Hybrid Algorithm of Set-Based Particle Swarm Optimization for Traveling Salesman Problem
Tao Liu, Michiharu Maeda · Journal of Signal Processing · 2013
This paper is concerned with the discrete combinatorial optimization problem.A modified hybrid algorithm that combines the max-min ant system and set-based particle swarm optimization (MSPSO) is proposed to solve the traveling salesman problem (TSP).To avoid a local solution, the cooperative mechanism among individuals is applied in MSPSO.MSPSO is based on set-based particle swarm optimization (SPSO).Before the execution of SPSO, max-min ant system (MMAS) is executed to accelerate the convergence of the algorithm.The results of the numerical experiments show that the proposed approach is effective for solving the TSP.
