Call For Participation - The Chef's Hat Cup @ IJCAI2021


I. Aim and Scope


Most of the current Reinforcement-Learning solutions, although having
real-world-inspired scenarios, focus on a direct space-action-reward mapping
between the agent's actions and the environment's state. That translates to
agents that can adapt to dynamic scenarios, but, when applied to competitive
and/or cooperative cases, fail to assess and deal with the impact of their
opponents. In most cases, when these agents choose an action, they do not
take into consideration how other agents can affect the state of the
scenario. In competitive scenarios, the agents have to learn decisions that
a) maximize their chances of winning the game, and b) minimize their
adversaries' goals, while in cooperative scenarios b) is inverted. Besides
dealing with complex scenarios, such solutions would have to deal with the
dynamics between the agents themselves. In this regard, social reinforcement
learning is still behind the mainstream applications and demonstrations of
the last years.


We introduce here the Chef's Hat Cup, a competition that aims at the
development of the most challenging artificial players!


The competition is separated into two tracks: a competitive and a
cooperative scenario. In the first track, the participants will use the
already available simulation environment to develop the most effective
agents to play the Chef's Hat card game and be the winner. In the second
track, they will have to develop an agent that can increase the chances of a
dummy agent winning the game.
