[C#编程] 实验1_简单计算器
1、项目概述
该项目目标是设计开发一个支持连续计算的四则运算计算器myCalculator，通过单击按钮，输入并完成如4+5+6或5*8+16类似的连续计算，并将运算结果显示在输出文本框中，同时也具备清空、后退等功能。
2、设计步骤
计算器myCalculator的主要功能是完成加、减、乘、除四则运算，而且支持连续计算，如4+5+7-8或4*5-6等运算。连续计算的实现借助于开发工具中预定义的数据结构Stack（栈）实现，如流程图所示
1. Project overview
The goal of this project is to design and develop a four arithmetic calculator, mycalculator, which supports continuous calculation. By clicking the button, input and complete the continuous calculation such as 4 + 5 + 6 or 5 * 8 + 16, and display the calculation results in the output text box. At the same time, it also has the functions of emptying and retreating.
2. Design steps
The main function of calculator mycalculator is to add, subtract, multiply and divide, and it supports continuous calculation, such as 4 + 5 + 7-8 or 4 * 5-6. The implementation of continuous computing is realized by using the predefined data structure stack (stack) in the development tool, as shown in the flow chart (2020-01-14, C#, 240KB, 下载1次)
[C#编程] 八皇后试验
八皇后问题，是一个古老而著名的问题，是回溯算法的典型案例。该问题是国际西洋棋棋手马克斯·贝瑟尔于1848年提出：在8×8格的国际象棋上摆放八个皇后，使其不能互相攻击，即任意两个皇后都不能处于同一行、同一列或同一斜线上，问有多少种摆法。 高斯认为有76种方案。1854年在柏林的象棋杂志上不同的作者发表了40种不同的解，后来有人用图论的方法解出92种结果。计算机发明后，有多种计算机语言可以解决此问题。

[C#编程] CR6
RC6是在RC5的基础上设计的，它继承了RC5的优点，为了满足NIST的要求，分组长度为128bit，RC6使用了4个寄存器，并使用32bit的整数模乘运算，用于加强扩散特性。RC6更精确的表示是RC6— ，其中字长为 bit， 为加密轮数， 为加密密钥用字节表示的长度。一般情况下令 。本设计题要求实现RC6的加密和解密算法，能对文件实现加解密。
RC6 is designed on the basis of RC5, and it inherits the advantages of RC5. In order to meet the requirements of NIST, the packet length is 128bit, RC6 uses 4 registers, and the integer modular multiplication operation of 32bit is used to strengthen the diffusion characteristics. The more precise expression of RC6 is RC6 - in which the word length is bit, the number of encrypt rounds, and the length of the encryption key represented in bytes. The general situation is ordered. This design question requests to realize the encryption and decryption algorithm of RC6, and can encrypt and decrypt files. (2018-06-21, C/C++, 1KB, 下载0次)

由于五子棋比一字棋难，规则多，又有禁手限制，无法采用简单的搜索和加分方式。
为了分清各种情况的轻重缓急，我们采用一次性打分的策略：
对棋盘上的每个空位根据情况的轻重缓急，越重越争分越高，反之越低，然后根据打分找出分值最高的的位置下子。
打分事实根据有：是否赢棋（最高），对方是否要赢棋，是否禁手，可形成四连的个数，和形成三连（包括活三）的个数，对方可可形成四连的个数，和形成三连（包括活三）的个数，等等。
本算法的好处在于，既有攻又有守，而且攻守较严。
