The first 10 Prolog Programming Contests took place in Ithaca (1994), Portland (1995), Bonn (1996), Leuven (1997), Manchester (1998), Las Cruces (1999), Paphos (2001), Copenhagen (2002), Mumbay (2003) and Saint-Malo (2004).
The contest organisers have written this book, containing the (slightly reworked) questions and an answer (in Prolog of course) for each question. Hardcopies of this book are still available, and can be obtained by sending an e-mail to bmd at cs dot kuleuven dot be. The book is now also freely downloadable on this page.
All the solutions presented in the book can be downloaded separately below. Alternatively, they can be downloaded in one bundle. These solutions make use of predicates in the contest library contestlib.pl.
