Title Recursive Monkey Puzzle Solution - Project
Author Maxim C.L. Wrne
Author Email max.warne [at] blueyonder.co.uk
Description A recursive solution for a particular form of monkey puzzle called "To The Extreme" by Lagoon Games. There are 523,069,747,249 incorrect combinations - and just one correct combination! Program typically takes 2-3 seconds to solve the puzzle from scratch.

Warne // // // // A recursive solution for 'Professor McBrainy's Zany to the Extreme Puzzle' // // This puzzle is a traditional 'monkey puzzle' - with surfers, skaters etc. // // substituted for the poor monkeys. Its grid is 4x4, giving 529,069,747,249 // // incorrect combinations, and one correct combination. // // // // Usage: Just call TTESolve (2 or 3 seconds on a modern computer), then // // iterate over TTEBoard calling TTEPieceAsText on each element to produce // // human-friendly output. Note that TTEInitialize randomizes the order and // // rotation of the pieces, so TTESolve starts from scratch each time -hence // // the running time of TTESolve varies. // // // // Unit originally authored using Delphi 6, but uses no VCL or OO so should // // port without trouble to just about any flavour of Pascal. // //////////////////////////////////////////////////////////////////////////////// interface type TTTESide = (NULL, SURF_BLACK, SURF_BLONDE, SKATE_GREEN, SKATE_RED , SNOW_GREEN, SNOW_MAUVE , WIND_BLACK , WIND_BLONDE);
