The traveling salesman problem (TSP) is one of the most widely
studied NP-hard combinatorial optimization problems and
traditional genetic algorithm trapped into the local minimum
easily for solving this problem. Particle Swarm Optimization
(PSO) algorithm was developed under the inspiration of behavior
laws of bird flocks, fish schools and human communities.
Compared with the genetic algorithm, PSO algorithm has high
convergence speed. In this paper, aim at the disadvantages of
genetic algorithm like being trapped easily into a local optimum,
we use the PSO algorithm to solve the TSP and the experiment
results show the new algorithm is effective for the this problem.
This paper introduce the PSO algorithm for TSP, we use
the proposed algorithm for solving the combinatorial
problem: TSP, the new algorithm shows great efficiency
in solving TSP with the problem scale from 52 to 1432.
By analyzing the testing results, we reach the conclusion:
in the optimization precision and the optimization speed,
the new algorithm is efficiency than the genetic algorithm
in coping with the TSP.
