At the end of the PyRat course, we organize a tournament between the programs developed by the students.

This tournament is an opportunity for you to see if you have made the right choices, but also to have a good time!

Snapshot of the 2019-2020 PyRat tournament.


We will ask you some time before the tournament to send us your AIs, and we will make one pool per group of students. Deadline for tournament submission is on October 26th.

In order to participate, you should first export your AI from Google Colab in .ipynb format. Additionally, write a short .txt document giving:

  • The name of the students of the team;
  • The name of your AI;
  • The number of your group;
  • Your campus.

Then go to Moodle at this link and submit an archive containing both files!

Tournament procedure

Unfortunately, we won’t have time to get everyone to compete in the final tournament. Consequently, we will proceed in the form of pools in which all players will compete against each other, in two winning rounds.

In each pool, we will keep the best program, i.e., the one with the highest number of points in the pool matches (1 point for a win, 0.5 for a tie). In the event of a tie after all matches, we will consider as best program the program with lower total execution time.

Once the winners of the pools have been determined (16 AIs), the tournament itself will take place in an amphitheater. The matches will be randomly determined.

The tournament tree. Only one program will reach the top!

The winner of the tournament will win a trophy, and their AI will serve as the final boss for next year’s students!

PyRat parameters used

  • Width 31, height 29;
  • Wall probability 0.4;
  • Mud probability 0.1;
  • 41 pieces of cheese (victory if 21);
  • 3s of pre-processing, 100ms per turn.

Some advice

Here are a few things you should keep in mind before submitting your code:

  • Make sure your program works both as a rat and a python;
  • Take some margins on computations time, as the computer on which the tournament is run may be less powerful than your personal computer.

Here are a few videos that were taken since the PyRat course was created! Some are more commercial than others, but that’s a cool overview of the atmosphere during the tournament, as well as a glimpse on the various versions of the game!
