鲍威尔法是搜索方法基本模式的扩展，它是使用最广泛的直接搜索法并且可以证明是一种共轭方向法[6.7]。一个共轭方向法将减少二次函数有限的步骤。由于一般的非线性函数可以近似...

A framework is a reusable, semi-complete application that can be specialized to produce custom applications. Like people, software applications are more alike than they are different. They run on the same computers, expect input from the sa...
