Parameter Identification of Ship Lateral Motions Using Evolution Particle Swarm Optimization

An evolution particle swarm optimization(EPSO) algorithm is proposed to solve the problem that particle swarm optimization(PSO) is easily trapped in the local minima. The EPSO is applied in the parameter identification of ship lateral motions. In order to increase the diversity of particle, a new evolutionary strategy in the standard PSO algorithm is introduced. Firstly, in the iterations of algorithm optimization process, EPSO algorithm is...
