Bot Bowl I

Bot Bowl I was the first AI competition in Blood Bowl! The competition uses the Fantasy Football AI (botbowl) framework and the results were be presented at the IEEE Conference on Games in London, 21st August, 2019.

Bot Bowl I featured one track which used the traditional board size of 26×15 squares with 11 players on each side. Participants are, however, limited to use a prefixed human team. In future competitions, we plan to allow all teams and the option to customized rosters.

Bot Bowl I had four bot submissions and we added the Random agent baseline to the competition. The first phase of the competition consisted of a round-robin tournament where all bots played every other bot 10 times.

Submitted bots:

  Random NO ONE GrodBot EvoGrod A2C Wins Ties Losses
 Random 0/5/5 0/0/10 0/0/10 0/10/0 0 15 25
 NO ONE 5/5/0 0/0/10 0/0/10 3/7/0 8 12 20
GrodBot 10/0/0 10/0/0 4/5/1 10/0/0 34 5 1
 EvoGrod 10/0/0 10/0/0 1/5/4 10/0/0 31 5 4
 A2C 0/10/0 0/7/3 0/0/10 0/0/10 0 17 23

GrodBot and EvoGrod were the best two bots in the round-robin tournament and thus played a final best-of-five series to find the winner. Here, GrodBot won with three wins and one tie in four games. Videos of the finals with commentaries by bzl11 can be seen below:

Analysis by bzl11

The two bots play very similarly, which is not at all surprising. Things they need to improve on:

We hope to see these things improved in the bots that will be submitted to Bot Bowl II. which will either be in the summer of 2020.
