【Abstract】 Because of the weak capability in local search and the lack of precision in the standard Genetic Algorithm(GA), a new algorithm —— the Dual Population Genetic Algorithm embedded in Evolution Strategies(ESs) —— is proposed. This algorithm is used to optimize toward the general population with a self adaptive GA and to look for toward the local population with Evolution Strategies. This algorithm is applied to nonlinear optimization problems with restraining conditions and the results show that the ability in local research, the precision of the calculation speed and its speed are greatly improved.
【Key words】 the Dual Population Genetic Algorithm; Evolution Strategies; nonlinear program; optimization with restraining conditions;
