有效集法利用数学规划的对偶理论,将所求双层规划转化为一个下层只有一个无约束凸二次子规划的双层规划问题.然后根据两个双层规划的最优解和最优目标值之间的关系,提出一种简单有效的算法来解决非增值型凸二次双层规划问题.(Quadratic Bilevel Programming 　)

全局牛顿-拉普森方法求解非线性方程组，自动搜索步长，进一步保证了程序的收敛(Global Newton-Raphson method for solving nonlinear equations. The steps can be found automatically. The convergence is better than the common Newton-raphson method.)

converts binary sequence to decimal sequence

说明：  非线性方程 Aitken加速收敛方法 二分法 割线法 牛顿微分改正方法(Nonlinear equation Aitken accelerated convergence method Dichotomy method Secant method Newton's differential correction method)

《最优化理论与方法》书籍中的乘子法的源程序，该书中的很多案例都用此方法试验过，本代码是一个小案例，将目标函数和约束函数按自己的需求换掉就能进行所期望的运算(" Optimization Theory and Methods" books multiplier method of the source, the book' s many cases are tested using this method, the code is a small case, the objective function and constraints to replace it according to their needs can perform the desired operation)

该程序为fluent软件进行速度入口造波数值模拟，波浪为二阶stokes波(The program for the FLUENT software simulation of wave speed entrance numerical, two order Stokes wave)

说明：  分子动力学模拟的简化版。PDF文件中包含了伪代码。(a simple example for molecular dynamics)
