Description

For the puzzle, see here: http://blogs.mathworks.com/videos/2009/07/28/puzzler-rules-of-the-new-game/

I have chosen for a flexible setup, the basic principle is this:

1. generate all possible boards for a number ('lookAheadMoves') of moves ahead.
2. use some criteria ('rankBoardMethod') to rank all possible outcomes
3. adjust the board with a number ('maxNewMoves') of the moves that lead to the highest ranked outcome
4. continue 1 to 3 until board is solved or maximum moves is reached

you can play around with the number of alternative boards created, and with the ranking method. If the number of alternative boards is very high, the algorithm is guaranteed to find the optimal solution. With a large number of colours (options) and a large board this becomes computationally infeasible.
