0 / 1背包问题是一个N P
0 / 1背包问题是一个N P-复杂问题，为了解决该问题，，将用回溯算法解决该问题。既然想选择一个对象的子集，将它们装入背包，以便获得的收益最大，则解空间应组织成子集树的形状（如图1 6 - 2所示）。该回溯算法与4 . 2节的装载问题很类似。首先形成一个递归算法，去找到可获得的最大收益。然后，对该算法加以改进，形成代码。改进后的代码可找到获得最大收益时包含在背包中的对象的集合。-0/1 knapsack problem is a P-complex issues, in order to solve the problem, and will be used backtracking algorithm to solve the problem. As to the choice of a subset of object, they will load a backpack, in order to obtain the greatest profits, the solution should be organized into space subset of the shape of the tree (Figure 1 6-2 below). The backtracking algorithms and 4. Two loading problem is very similar. Forming a recursive algorithm to get the maximum benefit available. Then, this algorithm is modified to form code. Improved code can be found at the maximum benefits included in the backpack of a collection of objects.

OFELI is an object oriented library of C++ classes for development of finite element codes. Its main features are : * Various storage schemes of matrices (dense, sparse, skyline). * Direct methods of solution of linear systems of equations as well as various combinations of iterative solvers and preconditioners. * Shape functions of most "popular" finite elements * Element arrays of most popular problems (Heat Transfer, Fluid Flow, Solid Mechanics, Electromagnetics, ...).-OFELI is an object oriented library of C++ classes for development of finite element codes.

Two strings to find the longest common sub
找出两个字符串的最长公共子串。
给出一个字符串，请删除该字符串的前导空格和尾随空格，中间的空格若多余1个删减到1个。
我是个菜鸟，但软件会是我终生的事业~我有信心学好它，希望站长通融-Two strings to find the longest common sub-string. Given a string, remove the string leading spaces and trailing spaces, if the extra spaces in the middle of a cut to one. I was a rookie, but the software will be my lifelong career ~ and I am confident to learn it, and hope that owners accommodation

SOR超松弛迭代法解线性方程组（C语言）
现有大多数迭代法不是对各类线性方程组都有收敛性,在解题时要对原方程组矩阵作一根本的变换,从而可能使条件数变坏,
也可能破坏了变换前后方程组的等价性,以及丧失使原方程组的对称性。但是SOR迭代法可以避免这类问题
