From these articles i am inviting U all to come and solve this problem.
This difficult problem was developed by Dr Arto Inkala, an environmental scientist with a doctorate in science and applied mathematics, compiles puzzles as a hobby. He says he slogged over this one for three months and used a customised computer software that ran through billions of calculations. It rivals the AI Escargot grid he drew up in 2006 — widely regarded as the most difficult sudoku grid yet.
So If you’re in the habit of solving a sudoku puzzle over your morning cup of chai, beware. This one might hold you up till dinner. Or longer. A mathematics wizard at Helsinki University in Finland has developed a sudoku which is so tough that it requires those attempting it “to think ahead eight or nine steps at a time”.
