Abstract
As the inertia weight is an important parameter in particle swarm optimisation to balance global search and local search, a new PSO algorithm based on modified inertia weight is proposed. In initial stage of the evolution, the algorithm uses the strategy of dynamic and self-adaptive inertia weight based on different dimensions and different particles to accelerate the convergent speed. In later stage of the evolution, it uses the strategy of linear degressive inertia weight ( LDIW), at the same time introduces timely the chaotic mutation to increase the diversity of population for preventing the local optimum. Testing results on five typical test functions show that this algorithm improves the performances on speed of convergence, precision of convergence, stability and capacity of global search to a great extent than those of LDIW-PSO.关键词
