You submit by sending an e-mail with any number of your solutions to bmd@cs.kuleuven.be.
The Subject line in your e-mail should say "PPC2007"
Your e-mail should contain the solutions in plain asci (no attachments) and have the structure:
%%%%%%%%%%%%%begin submission%%%%%%%%%%%%%
Name(s): monica geller, rachel green, phoebe buffay
Affiliation(s): friends
Prolog system used: joeylog
%%%%%%%%%%%%%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, more than one team will be declared the winner.
You can use any of the following Prolog (or Prolog-like) systems: SWI-Prolog, GNU-Prolog, SICStus Prolog, XSB, Yap, ECLiPSe, CIAO, B-Prolog. 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.
Here are the problems - at 16h30 9 September (Porto time) - it might take some minutes (because the contest needs to start first in Porto) and a reload of this page. Sorry it took so long - it is there now.
