蚁群算法解决TSP问题，验证过的，运行乜有问题，希望多多交流！(Ant colony algorithm to solve TSP, verified, run what-have problems, I hope more exchanges!)

In this document has been introduced comprehensively how to solve different partial differential equations .Everbody can solve Heat Conduction Equation, Helmholtz Equation, Laplace Equation and Wave Equation for different initial and boundary conditions. This document is elemantary of to understand how to solve partial differential equations with the aid of a porgramming language.

霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。(Specific methods Huffman coding: the probability of emergence of the size press line, the two smallest sum probability, as a new probability and the probability of re-queue the remaining, then the minimum of two probabilities are added, and then re-queue, until finally become one. Each time the sum will be 0 and 1 Fu added two probabilities, when read by the symbol has come to begin the final 1 , the route will encounter a 0 and 1 at the lowest to the highest bit of the right order, that is the symbol of the Huffman coding.)
