limit
- 极值法是一种重要的数学思想和分析方法。化学上所谓“极值法”就是对数据不足而感到无从下手的计算或混合物组成判断的题目，采用极端假设（即为某一成分或者为恰好完全反应）的方法以确定混合体系中各物质的名称、质量分数、体积分数，这样使一些抽象的复杂问题具体化、简单化，可达到事半功倍之效果。 -The extremum law is an important mathematical thinking and analytical methods. Chemical on the so-called &qu
Quasi-Newton-Methods
- 拟牛顿法(Quasi-Newton Methods)是求解非线性优化问题最有效的方法之一。其实DFP算法、BFGS算法都属于拟牛顿法，即，DFP、BFGS都分别是一种拟牛顿法-Quasi-Newton method (Quasi-Newton Methods) is one of the most effective methods for solving nonlinear optimization problems. In fact, the DFP algorithm, BFGS algo
