发帖数: 428 | 2 这个公式明显是错的，正确的递归公式应该是
f(x) = x-2 + f(x-1), 当 x > 2 时。 |

发帖数: 428 | 6 其实不是仔细，因为以前考虑过这个问题。大空中紧倒数第二口气时
对方必须提子，等于最后两口气不费手数，所以递归时需要减二。 |

发帖数: 13752 | 7 这个倒是常识，写成公式就是另一回事了。
从实战来说，可以记下面这样一张表（和missbear说的是一回事）
眼的大小 气数
1 1
2 2
3 3
4 5
5 8
6 12
>=7 无穷（做活了） |

在边角的时候大眼的气就不一样了，边角的特殊性 |
|
d***a
发帖数: 13752 | 9 这个补充得好。例如角上的方四，就只有三气。
在边上的方四，丁四，刀五，花五，花六，倒是不会少气。 |

发帖数: 428 | 10 》 在边上的方四，丁四，刀五，花五，花六，倒是不会少气。
再来仔细一次。 ：）
如果刀五的刀把在边上，还是可以少气，因为可以扑劫。花六也有此问题。 |

发帖数: 13752 | 11 你是说这样黑1, 3, 5成劫吧？但实际上，黑第一步得在x位点眼，
否则白就要做活了。 |
|
R*******n
发帖数: 428 | 12 通常情况下你是对的。但有些特殊情况我说的短气问题就会出现。
比如假设你的图里外围黑棋被完全包围，而包围它的白棋只有三
口气。这时，在别处打劫。如果白走你说的X位，则不是劫材，
但如果走1位就是劫材，因为黑只剩三口气了。
我是搞数学的，比较喜欢钻构造这种特例。：） |
|
d***a
发帖数: 13752 | 13 这样说勉强了。白如果是方四，黑有四气，黑就有四个劫材，但并不能因此就说，
这不再是白五气对黑四气的情况了。:-) |

发帖数: 1686 | 14 答案基本正确，成绩给一个A。
标准答案我不敢说，抛砖引玉吧：
首先我们分析一下黑白双方外面的子。由于收外气的缘故，黑白外面都如铜墙铁壁一般得
厚。于是这里面的死活只是目数问题，和全局厚薄没关系。这点先要铭记在心。
然后我们看死活。假如白棋不脱先，直接紧公气，那黑棋再在白眼里扑一手，白提劫。双
方形成紧气劫。白花2手提掉，黑在外面随便走2手。这样我们算算帐：白连吃带拔共有43
目。黑全死，有0目。
那白脱先呢？黑又扑了一手，大致成双活。(注意是大致，下面仔细说。)白棋在外面多走
了一手。现在算算帐：先不管劫，那样黑棋1目，白棋5目。和上面比较：白少38目，黑多
1目。也就是说：双方3手棋才共或得39目的利益。平均一手13目。在开局阶段显然太小。
所以白脱先。
刚才说大致成双活，现在解释一下。白脱先黑扑后形成一个打劫双活。公气是禁区，谁走
谁倒霉。白要是一走，自杀。黑全提掉。那黑走呢？那白棋提劫，成紧气劫，而且是白的
先手劫。这不是和刚开始的时候白先动手一样吗？也就是说黑棋白白走了2手棋，什么意
思也没有。
双方要动手，都只能从劫开始。黑沾劫。铁双活，结束。但是，黑化了2手棋，也就是说4 |

Somebody yesterday told me that he was be your Shifu
ten years ago, now you grow up they grow old.
Anyway they only
play doubles now, they are very good at volleys, running
a lot is not fair for them. Quite a few dropshots in this video
are really bad, I believe I would have lost the point if
it is against myself.
Still working on it. Do not like to practice things are righteous,
just like things that are evil :) |

发帖数: 583 | 44 We played a friendly match with your old team last sunday,
they now played exclusively within themselves. They are half
joking when they said Laoying is your shifu. They basically
meant that some of them watched you grow to a top amateur
player. It's natural that they are proud of you.
Sounds like you outgrow Realfan, I always thought he learned
tennis more recent than you :)
