Hi, Dana:

I had trouble with these rules, too. My problem was with #11, i.e. "The
Giraffe and the elephant live in houses separated by the blue house."

If I interpret that as "The Giraffe and the elephant live in houses separated
ONLY by the blue house", I can't find a solution, either.

OTOH, if I interpret it to mean that can be ONE OR MORE houses between the
giraffe and elephant, and one of them is blue, I also came up with 2
solutions.

#1 is the same as Herbert's. #2 is identical to #1 except that (like your
solutions) the giraffe and elephant are interchanged.

But I didn't do any of it with formulas or programming. I did it manually.

Hi. I may be wrong, but my program keeps telling me that there are no
solutions. It doesn't like clue # 14. Are you sure this is correct?
(14. The horse lives in the middle house.)

If I remove clue #14, I get two solutions. The only difference that I show
is only a giraffe or a elephant going into house #3 (middle house).
