This month we asked our readers to use their favorite BR/DM tools or just common sense to solve a simple puzzle “Which box contains the gold?” The very first quick solution by Jan Vanthienen uses decision tables to classify different possibilities. It’s interesting that these decision tables don’t need to be executable as their design already resolves the problem. Of course, as Jan wrote, “a general formulation of the problem will be better” and probably a larger problem with more objects and known relationships between them (e.g. notorious Zebra Puzzle) would be more difficult to solve without a tool. Let’s wait for more solutions. Link
