The 16th Prolog Programming Contest

The ICLP 2009 Contest

The 16th Prolog Programming Contest takes place at the occasion of ICLP 2009 at 6pm on July 15 in Pasadena (CA), USA.

The supported Prolog systems are SWI-Prolog and Yap.

The Web Contest

At the same time as the ICLP 2009 contest, a web contest will be organized, open to all. No pre-registration is necessary for the web contest.

The problems will be available here at 6:13pm on July 15, 2009. You can submit solutions until 6:13pm local Pasadena time on July 16, 2009.

You submit by sending an e-mail with any number of your solutions to toms @ cs.kuleuven.be. The Subject line in your e-mail should say "PPC2009". Your e-mail should contain the solutions in plain ASCII (no attachments) and have the structure:

%%%%%%%%%%%%%begin submission%%%%%%%%%%%%%

Name(s): will smith, pierce brosnan, mel gibson
Affiliation(s): mgm
Prolog system used: hollylog

%%%%%%%%%%%%%floop.pl%%%%%%%%%%%%

your solution that had to be in floop.pl

%%%%%%%%%%%%%bla.pl%%%%%%%%%%%%

your solution that had to be in bla.pl

%%%%%%%%%%%%%end submission%%%%%%%%%%%%

You can send e-mail as often as you want: only the last e-mail will be taken into account for correctness of solutions and timing - once more, so that you understand what you are doing: we will look only at your last e-mail (send within the 24 allotted hours), meaning that you must include everything you want us to take into account in that last e-mail, even the solutions you have send before, even if you haven't altered them since.

The order (for deciding the winner) is defined as follows:

• first based on the number of correct solutions,
• then based on the time stamp of your last e-mail.

In case of a tie, the speed of the solution to the problem designated as such in the problem statement is decisive, and if not, more than one team will be declared the winner.

You can use either SWI-Prolog or Yap. But you have to use the same system for every solution ! If you are a developer of any of these systems, the chances are high that you have access to a version that I do not have. It is in your interest to avoid that this causes problems.

It is unlikely that we will be able to reply to e-mails you send us during the contest, and even in the next days after the contest.
