Software for Large-scale Bound-constrained or Unconstrained Optimization L-BFGS-B is a limited-memory quasi-Newton code for large-scale bound-constrained or unconstrained optimization. The code has been developed at the Optimization Technology Cent

共轭梯度法，以及几种常见的的优化方法程序-Conjugate gradient method

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
