£770,000 could be yours

I know there is a fair few clever members on here so to get your brain working overload and with a bonus cash reward we just need the solution to this simple chess puzzle. Once solved feel free to PM me how you solved it ( please do not post your answer publicly ) I jest of course Grin

 

Serious hat on?  http://news.sky.com/story/scientists-offer-1m-prize-to-solve-simple-chess-puzzle-11015899

 

The puzzle requires a player to place eight chess queens on an 8x8 chessboard so that no two queens are threatening each other.

For an 8x8 chessboard, the solution requires that the queens don't share the same row, column, or diagonal - the directions in which chess queens can move.

Considered as a mathematical problem, computer scientists have calculated there are 4,426,165,368 possible arrangements of the queens but of these arrangements, only 92 are acceptable solutions.

Originally devised in 1850, the 8x8 puzzle has been solved by humans - but once the size of the chess board increases enough, computer programmes have found it impossible to solve.

Very good @journeys was this too easy for you? we are half way there folks, full credit to @journeys all we need now is to turn his solution into a computer programme that solves this as quickly as he did.
