拟牛顿法(变尺度法)DFP算法。用C/C++语言实现了该算法。-The quasi-Newton method (DFP) DFP algorithm. With the C/C++ the algorithm language.

本代码为《最优化理论与方法》书籍中的牛顿法和拟牛顿法算法的代码，并举了2个书上的作业题的例子，本代码中的目标函数和约束等初值可由需要进行改变，来得到所期望的计算-The code for the " optimization theory and method" books in the Newton method and quasi-Newton method algorithm code, citing two books on the example of the job

拟牛顿算法，一种解决全局最优化问题很好的算法，经测试效果很好-Quasi Newton algorithm, a good algorithm to solve the problem of global optimization, the test result is very good
