Recently, I came up with one such project that might work here, and I spent some time prototyping it. The project is to create an application in Pharo that can solve the "Zebra Puzzle".
What's the Zebra Puzzle? It's an example of a "constraint satisfaction problem", which are also known as "logic puzzles". This particular puzzle was published in Life International Magazine in 1962 and consists of a set of constraints for allocating a set of values (properties) of attributes in a mutually-exclusive way: 1. There are five houses. 2. The Englishman lives in the red house. 3. The Spaniard owns the dog. 4. Coffee is drunk in the green house. 5. The Ukrainian drinks tea. 6. The green house is immediately to the right of the ivory house. 7. The Old Gold smoker owns snails. 8. Kools are smoked in the yellow house. 9. Milk is drunk in the middle house. 10. The Norwegian lives in the first house. 11. The man who smokes Chesterfields lives in the house next to the man with the fox. 12. Kools are smoked in the house next to the house where the horse is kept. 13. The Lucky Strike smoker drinks orange juice. 14. The Japanese smokes Parliaments. 15. The Norwegian lives next to the blue house. Now, who drinks the water? Who owns the zebra? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
