很有用的，一些经常用到的C算法程序集。

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

在一个圆形操场的四周摆放着n堆石子。现要将石子有次序地合并成一堆。规定每次只能选相邻的2堆石子合并成新的一堆，并将新的一堆石子数记为该次合并的得分。试设计一个算法，计算出将n堆石子合并成一堆的最小得分和最大得分。 编程任务：对于给定n堆石子,编程计算合并成一堆的最小得分和最大得分。-Playground in a circle around the stones are placed n heap. Stone is to have the order to merge into a pile. Provisions can only choose 2 adjacent stones piled into a heap of new and new pile of stones a few in mind for its combined score. Try to design an algorithm to calculate the n heap into a pile of stones the minimum scores and maximum scores. Programming tasks: for a given n stack stone, into a pile of programming the calculation of the minimum scores and maximum scores.

资源描述本程序是大一时候写的一些小程序，这里是万历年的基本算法，其中谭浩强书中经典的闰年算法，可以供初学者学习，练习，更改。

简单的马尔科夫算法，Markov链数据提供了有当前状态决定，而又独立于当前状态的序列，此处算法是将给定的文本串生成新的随机文本- Simple Sample of a Markov Chain Algorithm：A markov chain is a sequence of random variables in which the future variable is determined by the present variable but is independent of the way in which the present state arose from its predecessors. The code is a simple example of a markov chain that generates somewhat random text output from a given text input.

lda模型，用java语言写的，我想做些lda文本分类的实验，这里面有关的一些算法，我自己有些也没有明白，希望各位大神能给看看，帮忙解决下问题。

Market Newman写的复杂网络的加权GN算法 算法用Python写的 其基本思想是不断的删除网络中具有相对于所有源节点的最大的边介数(ege betweenness)的边，然后，再重新计算网络中剩余的边的相对于所有源节点的边介数，重复这个过程，直到网络中，所有边都被删除。
