一些重要的有关地球物理计算的软件算法程序！！很有用的

天然气管道连接问题原程序，一百个用户，其中有四个无效用户，将其它96个有效用户连接成一个树形网络，用kruskal算法实现-Natural gas pipeline to connect the issue of the original procedure, 100 users, which has four invalid users, will the other 96 valid user to connect into a tree network, using Kruskal Algorithm

本算法是在多峰值函数找最优解，粒子群算法收敛速度快  ，精度高的优点。 代码清晰明了，有注释，可以帮助初学者很好的掌握，能够看懂 ！

八皇后问题的解法，非常好，请大家看一下，谢谢了-8 Queen" s problem solution, very good, please look at, I would like to thank the

资源描述最小权三角剖分问题是求最小总边长三角网的问题。这是一个多边形，输入或输入点集后必须细分为三角形，满足边缘到边缘和顶点到顶点，以这样的方式来减少三角形的周长的总和。

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.
