罚函数内点法程序
说明： 一种用C＋＋编的罚函数内点法进行的优化程序设计，解决有关优化问题，可以使用，抄来的，仅供己用(a C++ compile penalty function interior point method for optimizing the design process and solve the optimization problem, it can use, copied, only for their own use!)

Matrix multiplication problem is a typical example of dynamical programming.
Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.
For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix.
There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C).
The first one takes 15000 elementary multiplications, but the second one only 3500.
Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.

VB采用最小二乘法演示如何在VB中实现线性拟合和二次拟合，编译时候需要TeeChart5.ocx，已将此文件打包，你无需再下载。新建 Microsoft Excel 工作表.xls里是测试数据，程序会自动读龋这里要说的是：
1.1 线性拟合：给定一组数据（xi，yi），i=1，2，…，m，做拟合直线。
1.2 二次拟合：给定数据系列（xi，yi），i=1，2，…，m，用二次多项式函数拟合这组数据。作出拟合函数与数据序列的均方误差最校
(VB using the method of least squares linear fit and demonstrates how to implement a quadratic fit in VB compiler when needed TeeChart5.ocx, has packed this file, you do not need to download. Newly built in Microsoft Excel worksheet xls test data, the program will automatically read caries say here is: 1.1 linear fit: Given a set of data (xi, yi), i = 1,2, ..., m, do fitting a straight line. 1.2 quadratic fit: given data series (xi, yi), i = 1,2, ..., m, with a quadratic polynomial function fitting this set of data. Fitting function to the data sequence with the best mean square error correction)
