AbstractWith the rapid development of recent computer, a variety of board games are one after another sign of the computer, so those who love chess, they often suffer from rival chess fan who has not been enough to keep chess addiction. And high levels of all such software, a great rival and the tendency of the human brain. Which had defeated world champion chess - Garry Kasparov's "Deep Blue" is the most convincing representatives; other like the Go "light hand" chess "to family" and also for its excellent deep artificial intelligence by chess fan favorite; and we will tell you is that backgammon algorithm.In order to make the reader have a backgammon search complexity image understanding, to cite a Chinese chess with backgammon comparison searches. Can see that compared with Chinese chess, backgammon coefficient of multi-branch, and the outcome of conditional also complicated. Significant factor in the branch, the search procedure to increase the maximum search depth of 1 level, cost of computation time will increase significantly. Therefore, to design an efficient search algorithm is very important.Keywords : backgammon, Human Versus, Algorithm.前 言五子棋是起源于中国古代的传统黑白棋种之一。现代五子棋日文称之为“連珠”，英译为“Renju”，英文称之为“Gobang”或“FIR”（Five in a Row 的缩写），亦有“连五子”、“五子连”、“串珠”、“五目”、“五目碰”、“五格”等多种称谓。五子棋不仅能增强思维能力，提高智力，而且富含哲理，有助于修身养性。五子棋既有现代休闲的明显特征“短、平、快”，又有古典哲学的高深学问“阴阳易理”；它既有简单易学的特性，为人民群众所喜闻乐见，又有深奥的技巧和高水平的国际性竞赛；它的棋文化源渊流长，具有东方的神奇和西方的直观；既有“场”的概念，亦有“点”的连接。它是中西文化的沟通点，是古今哲理的结晶。1. 系统概述1.1 开发背景当前网络上流传的五子棋游戏功能并不尽善尽...
