Did you see the real world uses? like prolog was and may still be used in Windows? The puzzle examples are for educational purpose. Again I am just a noob, I learned Prolog and did some basic things years ago, a cool page I used to learn was this tutorial that implements a text based game , more refreshing then the tutorials with puzzles or the familiry http://www.amzi.com/AdventureInProlog/a1start.php http://www.amzi.com/AdventureInProlog/a1start.php The situation is maybe similar with GA(genetic algorithms) when you learn it you have some simple examples, when you want to solve a real problem things get complex fast(how to encode the problem,what fitness function should I use ...)
