标题Re: [请问] 一个小游戏的必胜战法（拈，3 5 7）
时间Mon May 4 17:06:42 2009
我想提供另一个去年 PuzzleUp 的题目...
算是变体的拈
(连英文一起贴, 这叫中英对照版:P)
Two persons are playing the following game:
两个家伙在玩下面这款规则的游戏:
The game will start as the first player selects any date
in January; and will continue with sides selecting dates
one by one. The player who selects Sunday, 31st of December
will win.
先由其中一个人开始, 选择一月的某一天。接着换另一个人再做
选择, 如此轮替下去。直到哪个人可以选到 12月31日星期天,
他就获胜。
‧ A date consists of three data. The day of the month
(1, 2, 3, ..., 30, 31); the month (January, February, ...,
November, December) and the day of the week (Monday,
Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday).
(Note: You will consider the length of each month. February
may last 28 or 29 days).
一个日期有三笔资料, 包含了『日』(1到 31),『月』(1月到12月)
以及『星期几』(星期一到星期日) (注意: 你要考虑月份的实际长
度, 二月你可以当成是28天或29天)
‧ The player who is in charge, can only raise one of the
three datas of the date selected by her/his opponent.
轮到哪个人时, 他只能更改他对手刚选择的日期, 当中三笔资料的
其中一笔。
‧ The raises in the data are unidirectional. That is, after
30, a player cannot select 1, 2, 3, ... 29 but only can select
31. Likewise, after October, only November and December; and
after Saturday, only Sunday can be selected.
资料的选择是不可逆的。举例来说, 当有人选了『日』是30, 那麽接
下来的人就不能在『日』这笔资料选 1到29, 唯一能选的是31; 另外
同理, 像是『月』选了十月, 那麽就只剩11和12月可以选择更改。星
期六一旦被选, 在『星期几』的选项中只能改成星期日。
If the first player selects 1st of January, Monday; what date
should the second player select, in order to secure to win
the game?
游戏开始了, 起始玩家选了1月1日, 星期一。那麽…
身为後选的玩家, 你要选择哪一天, 才能确保你一定胜利??
The following is an example of a game (played unskillfully)
between A and B:
A) 1st of January, Monday; B) 15th of January, Monday;
A) 15th of January, Friday; B) 31st of January, Friday;
A) 31st of December, Friday; B) 31st of December, Sunday.
[上面是个游戏过程双方选择的例子, 实在很懒得翻译…自己看吧]
