Programming of water pollution control system based on improved genetic algorithm

Programming of water pollution control system was focused. A corresponding model for the system design was established, which could be used in sewage treatment. Because of the high nonlinear character of the model, a new genetic algorithm based on descend searching operator was also put forward to solve the model, which not only was superior to the nonlinear program in the effects of the programming but also was superior to SGA in lightening the premature. The case study showed that the improved algorithm, being capable of optimizing the local and overall region, is adapted to optimizing complex models. The method to dispose the problems with some restraints was also proposed which could be applied to solve the similar problems. As a practicable example, this method was used to optimize the programming of the water pollution control system.
