LOGIC PROBLEMS (CSP)A logic problem is a puzzle associated with some text. A classic example is the zebra problem: There are five houses, each of a different color and inhabited by people of different nationalities, with different pets, different favorite drinks. and different favorite cigarettes. The English person lives in the red house. The Spaniard owns a dog. Coffee is drunk in the green house. The Ukrainian drinks tea. The green house is directly to the right of the ivory house. The Old-Gold smoker owns snails. Kools are being smoked in the yellow house. Milk is drunk in the middle house. The Norwegian lives in the first house on the left. The Chesterfield smoker lives next to the fox owner. Kools are smoked in the house next to the house where the horse is kept. The Lucky-Strike smoker drinks orange juice. The Japanese person smokes Parliament. The Norwegian lives next to the blue house. Who drinks water and who owns the zebra? Each puzzle has a different formulation.
