An improved differential evolution algorithm is given. In the algorithm a logarithm increased crossover and a random migration operator are used to overcome the convergent slowness in the later period of the iteration and fall easily into premature convergence. It is shown by the experiments on eight typical problems that the modified algorithm has strongly global search ability.
To deal with the problem of premature local convergence, slow search speed and low convergence accuracy in the late evolutionary, this paper proposes a particle swarm optimization algorithm based on velocity differential mutation (VDMPSO). Firstly, The cause of local convergence in the basic PSO algorithm is elaborated. Secondly, strategies of direct mutation for the particle velocity rather than...
Differential evolution (DE) is a novel evolutionary approach capable of handling non-differentiable, non-linear and multi-modal objective functions. DE has been consistently ranked as one of the best search algorithm for solving global optimization problems in several case studies. Mutation operation plays the most significant role in the performance of a DE algorithm. This paper proposes a new mutant...
