优化命题的解决存在于许多领域，对于国民经济的发展也有着巨大的应用前 景.随着优化对象在复杂化和规模化等方面的提高，基于严格机理模型的传统优化 方法在实施方面变得越来越困难. -Optimization solution proposition exists in many areas, for development of the national economy also has great application prospect. With the optimization of the object in a complex and large-scale areas such as the improvement of the mechanism model based on strict traditional optimization methods in the implementation has become more to the more difficult.
