Multi-Population Parallel Genetic Algorithm for Parametric Optimization in No-Linear System

Multi-population parallel genetic algorithm for parametric optimization of no-linear system is that while solving space is searched with the population genetic algorithm to realize the parametric optimization of non-linear system. The bad gene was eliminated through information exchange between individual in population, and information of solving space was reflected with fine individual to make the constringency of system is steady. Firstly, coding scheme, across and variation probability, function for degree of adaptability, strategy, genetic operator and mobility of individual were selected, the parametric optimization of no-linear system was validated with multi-population parallel genetic algorithm through saturated no-linear element, speed limitation element and third-order element.
