The book "Artificial Intelligence through Prolog" by N.C.Rowe,
published by Prentice-Hall (which coincidentally just turned up
in our library today) demonstrates my point. He uses asserts
and retracts all over the place to program AI search algorithms
(if Mr.Rowe reads this, I would be interested in hearing his
reasons for this, personally I think I would recommend his book
as a good demonstration of how NOT to program in Prolog).
