Text Based
A console app written in C that finds all words that can be derived from a set of characters. Good for cheating at scrabble, but can be slow when the input string is over 10 characters long. Includes source code and dictionary file.
Artificial Intelligence
A pathfinding algorithm optimised for use when the destination is known. Includes blitz basic source code and compiled demo program.
This is basically the A* algorithm with the heuristic removed. This means that it can perform searches when the target is unknown, or there are multiple targets. The downside is that its generally slower.
