![]() Most of life’s challenges don’t have black-and-white solutions, and many have no resolution at all. In an essay on sudoku that seemed especially relevant to today’s news, Will Shortz, The New York Times’s crossword editor, wondered whether it was all really about control: The jury forewoman said the sudoku-playing commenced early on in the trial, “probably when the surveillance evidence was on.”īut something other than boredom may account for the puzzle-mad Australian jury. Not so the testimony in the Australian drug case, it would seem. ![]() The grids of these puzzles seem to shut down the mental apparatus, enclosing one’s faculties in a tightly constrained universe - a 9 by 9 array that mustīe carefully filled up with the numbers 1 to 9, following certain rules. ![]() When it comes to sudoku, there is no escape. Back in 2006, Edward Rothstein of The New York Times offered a much different characterization of sudoku’s power to command attention: The court heard evidence in the case for 66ĭays, including testimony from more than 100 witnesses, 20 of them police officers.Īt the same time, the game can be more engrossing than the juror acknowledged. To be sure, the trial was a complicated one, the product of what was apparently a lengthy, complex investigation that yielded drug and conspiracy charges against two men. To maintain my attention the whole time,” she explained, according to The Associated Press. The judge was apparently less than persuaded by her assurances that “it helps me keep my mind busy paying more attention.” After all, “some of the evidence is rather drawn out and I find it difficult She admitted to having spent more than half of her time in court playing the game. She said four or five jurors had brought in the sudoku sheets and photocopied them to play during the trial and then compare their results during meal breaks. Puzzle solving during the proceedings, according to The Sydney Morning Herald: Judge Peter Zahra made the decision to abort the trial and discharge the jury after the forewoman admitted to a prodigious amount of Two years later, the number puzzle, which has its own section on, has succeeded in spoilingĪ federal criminal case in Australia, wasting almost $1 million in the process. In one of the first major signs that the game had grown into a phenomenon, British Airways told its 13,000-strongįorce of flight attendants in 2006 that they were forbidden to play sudoku during takeoffs and landings. It’s not a panacea like Tabling or Nishio but it is easier to do and will work better if you are down to your last twenty or so unsolved squares.Say what you will about the performance of the airline industry - it was first to identify a threat in sudoku. The solver worked it out, the most advanced strategy being used is "3D Medusa", really impressive.īowman’s Bingo doesn’t solve all ‘bifurcating’ Sudokus but if applied thoroughly it will crack more than 80% of them. I tried it by importing a Sudoku picked from the "very hard" level of a Android Sudoku App, on which I stuck quite a while. There's a online Sudoku solver, solving problem like a human (rather than a computer) with the following strategies. I heard some researcher accidentally found that their algorithm for some data analysis can solve all sudoku. How can a human being solve the so called "the hardest sudoku in the world", does he need to guess? Let us say the we know the solution is unique, is there any algorithm that can GUARANTEE to solve it without backtracking? Backtracking is a universal tool, I have nothing wrong with it but, using a universal tool to solve sudoku decreases the value and fun in deciphering (manually, or by computer) sudoku puzzles. Traditional sudoku means 81-box sudoku, without any other constraints. Here Guessing means trying an candidate and see how far it goes, if a contradiction is found with the guess, backtracking to the guessing step and try another candidate when all candidates are exhausted without success, backtracking to the previous guessing step (if there is one otherwise the puzzle proofs invalid.), etc. Is there any algorithm that solves ANY traditional sudoku puzzle, WITHOUT guessing?
