Ｆ－Ｒ程序，写的不错哈　拿出来与大家共同分享-F-R procedures, write out a pretty good Hana shared with you

此示例程序演示如何使用运算符projective_trans_object_model_3d 在成功的决窍。在此示例中一些多维数据集是通过不同的方式创建的。在那之后，多维数据集是与投影得到转型。

关于外排序的操作-outside of the sorting operation

这是一个用java高级编程语言编写的程序，实现了用“向上/向下修正方法”的拉格朗日插值公式计算某个函数的值，方便实用。-Java This is a high-level programming languages used in the preparation of procedures, implementation of the " up/down correction method," Lagrange interpolation formula of the value of a function, convenient and practical.

简单的后缀表达式求值-simple expression evaluates Suffix

无递归二叉树插入及中序等顺带求得深度等-Non-recursive binary tree insertion sequence, such as passing and seek depth

北京大学acm的题，1118题。找出在二维地图中共线的最多有多少个点。-Acm University of title, 1118 title. Identify two-dimensional map of the Chinese Communist line has a maximum number of points.

数据挖掘领域中的序列模式挖掘，基于时序特性对数据进行挖掘，得到具有时序特性的关联规则，现有的算法有很多，如AprioriAll和freespan算法等等，但是由韩家炜教授提出的prefixspan算法是较为优秀的序列模式挖掘算法，运行速度快，存储空间小，是很不错的高效算法。

设A和B是2个字符串。要用最少的字符操作将字符串A转换为字符串B。这里所说的字符操作包括： 1. 删除一个字符 2. 插入一个字符 3. 将一个字符改为另一个字符 将字符串A变换为字符串B所用的最少操作数称为A到B的编辑距离，极为d(A,B)。设计一个算法，计算任意两个字符串的编辑距离。 -Set A and B are two strings. Operation will use the least character string A is converted to a string B. Operation of characters are talking about here include: 1. Delete a character 2. Insert a character 3. Will be replaced by one character to another character will be transformed into a string A string of at least B operand used by A to B is called the edit distance is extremely d (A, B). Design an algorithm to calculate any two of the string edit distance.
