Sudoku at its most evil November 7, 2006 - 9:58AM A Finnish mathematician claims he has created the world's hardest sudoku puzzle, a brain-teaser that required three months' work and a billion combinations to produce. "AI Escargot is the most difficult sudoku puzzle known so far," the puzzle's creator and applied mathmetician Arto Inkala, 37, said. "I called the puzzle AI Escargot, because it looks like a snail. Solving it is like an intellectual culinary pleasure. AI are my initials," he added. According to a rating published on sudoku website http://www.sudoku.com, AI Escargot claims the top spot for sudoku's most baffling puzzles. Escargot demands those tackling it to consider eight casual relationships simultaneously, while the most complicated variants attempted by the public require people to think of only one or two combinations at any one time, Inkala said. AI Escargot has, however, been solved by sodoku experts, but its creator has promised to produce more challenging versions, as with Escargot, with the aid of computers. Sudoku, the invention of which is attributed to Swiss mathmetician Leonhard Euler in the 18th century, is a logic-based placement puzzle. The object is to fill a grid of nine squares with numbers so that every column and every row contains the digits one to nine.
