Q/F(Vt F*O [color=blue]数独（日语：数独　すうどく）是一种源自18世纪末的瑞士，后在美国发展、并在日本得以发扬光大的数学智力拼图游戏。拼图是九宫格（即3格宽×3格高）的正方形状，每一格又细分为一个九宫格。在每一个小九宫格中，分别填上1至9的数字，让整个大九宫格每一列、每一行的数字都不重复。 )^3Yp a1hlnZ
N7ZX8lh
数独的玩法逻辑简单，数字排列方式千变万化。不少教育者认为数独是锻炼脑筋的好方法。

历史
!FPy%[;g] 如今数独的雏型首先于1970年代由美国的一家数学逻辑游戏杂志发表，当时名为Number Place。现今流行的数独于1984年由日本游戏杂志《パズル通信ニコリ》发表并得了现时的名称。数独本是“独立的数字”的省略，因为每一个方格都填上一个个位数。

&JVVD'a5\ 数独冲出日本成为英国当下的流行游戏，多得曾任香港高等法院法官的高乐德（Wayne Gould）。2004年，他在日本旅行的时候，发现杂志的这款游戏，便带回伦敦向《泰晤士报》推介并获得接纳。英国《每日邮报》也于三日后开始连载，使数独在英国正式掀起热潮。其他国家和地区受其影响也开始连载数独。

数独的通解方法及步骤：

KK(~AV)T6?
\0D9R#Z4hsjD 根据以下方法可以确保最终得到数独的解，而且通过手工运算的时间基本可以控制在1.5个小时，不论难易程度，所以此方法可以作为取得数独答案的一般解法。 p R/n xS
1、根据横列、竖列和方格的限制条件排除各个点不可能的数字，并从1－9将各个可能的数字用小字体逐个写进每个空白的格子。（该步骤大约需要15－20分钟，这是求解的初始，务必确保没有遗漏）。
)~8A`jHo;v'q Sd,c.zh}IM._ |
2、审视第一步骤的结果，如果发现某个空格只有一个数字，即确定该空格为这个数字。并根据该数字审视其相关的横列、竖列和方格，并划除相同的数字。（该情况出现的可能往往不多，除了较简单的数独题，但这是一个必要的过程，而且在随后的过程中要反复使用此方法。） LwP6y-V/ZN
%d'i{IJj
3、审视各个横列、竖列和方格中罗列出的可能的数字结果，若发现某一个数字在各个横列、竖列或方格中出现的次数仅一次，则可以确定该空格的解为此数字。并根据第二条的方法排除与此空格相关列或方格中相同的数字。
w9q&v E X1E b
EB@+c KG2e:yE 4、审视各个横列、竖列和方格中罗列的各个可能的结果，找出相对称的两个数组合的空格（或3个、4个组合），并确定这两个空格（或3个、4个）的数字只可能为这两个数字，即两个数字在这两个空格的位置可以交换，但不可能到该行、该列或该方格的其他位置。根据此结果可以排除相关列或方格罗列出相关数字的可能，并缩小范围。（该步骤处理的难度相对复杂，需要在积累一定经验的基础上进行，也是最终求解的关键）
*l6JZgt0[l[ 4{%U%QM3h
5、反复使用2、3、4提到的步骤，逐步得到一个一个空格的解，并将先前罗列的各种可能的结果一个一个排除，使可能的范围越来越小，直至得到最后结果。[/color]X.D%j?(X$K

The difficulty of a puzzle is based on the relevance and the positioning of the given numbers rather than their quantity.

Most publications sort their [i]Sudoku[/i] puzzles into four or five rating levels, although the actual cut-off points and the names of the levels themselves can vary widely. Typically, however, the titles are synonyms of "easy", "intermediate", "hard", and "challenging" (also known as "diabolical" or "evil"). An easy puzzle can be solved using only scanning; an intermediate puzzle may take markup to solve; a hard or challenging puzzle will usually take analysis.(l:b P5}]]

'a1SPz'{ndO [size=6][color=indigo]Construction[/color][/size]Ke*ot-H|
Building a [i]Sudoku[/i] puzzle can be performed by predetermining the locations of the givens and assigning them values only as needed to make deductive progress. This technique gives the constructor greater control over the flow of puzzle solving, leading the solver along the same path the compiler used in building the puzzle. Great caution is required, however, as failing to recognize where a number can be logically deduced at any point in construction—regardless of how tortuous that logic may be—can result in an unsolvable puzzle when defining a future given contradicts what has already been built. Building a [i]Sudoku[/i] with symmetrical givens is a simple matter of placing the undefined givens in a symmetrical pattern to begin with.

The [i]Sudoku[/i] puzzles printed in most UK newspapers are apparently computer-generated but employ symmetrical givens; [i]The Guardian[/i] famously claimed that because they were hand-constructed, their puzzles would contain "imperceptible [url=http://en.wikipedia.org/wiki/Witticism][color=#0000ff]witticisms[/color][/url]" that would be very unlikely in computer-generated [i]Sudok[/i]

This puzzles requires multiple instances of Heuristic 1+ before succumbing to direct elimination methods. However, all of the inference chains are relatively easy to follow as they require no more than two pivots.

Under the default setting, the program gets to step 84 making liberal use of Heuristic 1+, i.e. chaining. To proceed further, you must set the 1+ limit, the length of the chains the program is allowed to use to derive a contradiction, to unlimited.
