实现了蚁群算法，程序精炼，结果正确，代码可直接引用，对于致力于基础算法研究的，有重要意义，参考价值较高。

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.

Code in java for the Traveling salesman problem. This code is very simple because has only three pages. It s works same.

对任意给定的二叉树（顶点数自定）建立它的二叉链表存贮结构，并利用栈的五种基本运算（置空栈、进栈、出栈、取栈顶元素、判栈空）实现二叉树的先序、中序、后序三种周游，输出三种周游的结果。- To wilfully assigns two forks the tree (to go against points from to decide) establishes it two to fork the chain table storage structure, and (sets at spatial stack after the stack five kind of fundamental operations, enters stack, sends out of the warehouse, takes stack top element, sentences stack to be spatial) realizes two forks the tree first the foreword, center the foreword, the foreword three kinds travels around, outputs the result which three kinds travels around.
