Abstract
To overcome the shortcomings of the traditional particle swarm optimization algorithm, which are easy to fall into local extreme, a new algorithm based on the simplified particle swarm optimization algorithm is proposed. Firstly, the proposed algorithm removes the speed term, so that it makes the algorithm simple. And then it improves the displacement term. Finally the nonlinearity of the trigonometric function is utilized in the algorithm to improve learning factors. It balances the global search and local search. The six basic test functions are used to compare the standard particle swarm optimization algorithm, the simplified particle swarm optimization algorithm and the improved algorithm proposed in this paper. Experimental results show that the performance of the improved particle swarm optimization is better than the other two algorithms.
