ABC.net.au reports that solving Sodoku mathematical puzzles involves the use of neural pathways that cannot currently be replicated by the most powerful computers. A new paper published by Princeton University Professor John Hopfield examines the brain processes we utilize when playing Sodoku. In order to solve the puzzle, our brains use a unique set of neural pathways known as associative memory, which enable us to discover patterns from partial clues. Currently, computers can store large amounts of data and process it quickly; but they are not yet able to incorporate sophisticated applications of associative memory. Hopfield includes an algorithm for associative memory in his paper, hoping it can be implemented in computer chips. One of the difficulties in solving a Sodoku puzzle is the sheer number of permutations of the pattern. However, each successful entry lowers the number of permutations. According to Associate Professor Andrew Paplinski from Monash University in Melbourne, the ability for computers to mimic associative memory would eventually give computers “extreme robustness of pattern recognition.” Currently, to process all of the required information would take an enormous amount of computation…
