A Few Words About Sudoku, Which Has None - New York Times (http://www.nytimes.com/2005/08/28/weekinreview/28shor.html?ex=1125374400&amp;en=b132781c8746bae1&amp;ei=5 070)

Why sudoku? And why now?

The craze started in England last November, when Wayne Gould, a
retired judge from New Zealand, persuaded The Times of London to print
the puzzle. Judge Gould had seen sudoku in a Japanese puzzle magazine
and written a computer program for creating sudoku at any desired level
of difficulty.

Japanese puzzle magazines are filled with novel and ingenious logic
puzzles. They are as popular in Japan as crosswords are in the United
States. But Judge Gould saw two things in sudoku that set it apart: the
rules, which can be stated in one sentence, and the size, which does
not vary with degree of difficulty.

Every puzzle craze in history has come along at an opportune time,
and the same is true of sudoku. The world's first puzzle craze,
tangrams, the seven-block puzzle introduced from China around 1817,
could not have been possible before significant international trade and
printing. The 15 Puzzle, in 1880, and Rubik's Cube, in the early
1980's, involved new manufacturing processes. And crosswords required a
high educational level in the general public and the ability of
newspapers to produce and print crossword grids easily, which did not
occur until the 1920's.

For its part, sudoku - a short form of the Japanese words meaning
"only single numbers allowed" - could not have become popular before
the rise of personal computers. Nearly all sudoku puzzles are computer
generated, using programs that understand all the logical solving
strategies, from the most basic to the most sophisticated, and so can
determine mathematically how hard or easy a puzzle is. Before
computers, it would have been laborious for a human to prove that each
sudoku puzzle has a unique solution, as it must, and almost impossible
for a human to rate its difficulty precisely.

E interesant dar nu cred ca ai ajunge chiar la dependenta... sau poate cine stie, daca exista vreo predispozitie dinainte?smileys/smiley36.gifsmileys/smiley36.gifsmileys/smiley36.gif
