Forums Word Play—Riddles and Puzzles. I don't want to ruin it, but I have the answer. To solve Einstein's puzzle, we represent each of the fifteen constraints as a regular language and intersect these languages with the initial set of all possibilities. If all goes well, at the end we will know who keeps fish. For example, we can interpret The Englishman lives in the red house. This constraint is trivial to encode because in our representation of a house, the color and the nationality are adjacent.

The fifteen constraints are shown below. All that we need to do to solve the problem is to impose the constraints on the row of five houses by intersection. The solution below is almost correct. The result is a network with five paths. In four of the solutions nobody keeps fish and the German keeps the same kind of pet as someone else.

According to the worksheet I was given this puzzle is attributed to Albert Einstein. Can you? This puzzle has been discussed on the Forum. Hide Ads About Ads.
