[DhtmlXQ_comment0]“在某些类型的局面里,电脑看得如此之深以致它弈得象上帝。” ——加里·卡斯帕罗夫||||带有残局库的电脑下残棋就如同上帝一样,洞悉一切,完美无缺。第一个针对炮兵对士象全的残局库是2002年吴韧博士(梦入神机的作者)制作的,在他当年的论文里发表了此惊人的发现:炮高兵单士相必胜士象全。由此打破了以往人们的认知,1930年代陈廉庸得出的结论--炮高兵单缺士必胜士象全。||||此局选自Ren WU & Donald F. BEAL合作的论文“A Memory Efficient Retrograde Algorithm and Its Application To Chinese Chess Endgames”MRSI Publications, Vol 42, 2002。在该论文中,吴韧博士介绍了他对于中国象棋残局数据库生成算法的研究结果,并在结尾录入了此局:最长的炮高兵单士相胜士象全的图形。红方走第95回合才能吃到黑方第一个子。原文中在95回合就结束了。我通过查询残局库又补充了后续的着法,直到红胜。||||需要说明的是,此局并非唯一的最长图形,里面的着法也并非是唯一的。原文中在主序列下提及了所有的最优着法,而我录入的时候全部省略。我也无法对其着法进行评论,我想这个残局实在是超过了人类的评价能力。除非你这样写“此手为红方最简明的胜法,只需181步,如改走XXXX则需要193步才能获胜”。“此手是黑方最顽强的着法,可以坚持180步,如改走XXXX则在172步后红胜”。所以干脆不要任何评论了,让我们一起欣赏上帝是如何下棋的。[/DhtmlXQ_comment0]
