  Between 2021 and 2023, AI-Olympics, a series of online AI competitions was
hosted by the online evaluation platform Jidi in collaboration with the IJCAI
committee. In these competitions, an agent is required to accomplish diverse
sports tasks in a two-dimensional continuous world, while competing against an
opponent. This paper provides a brief overview of the competition series and
highlights notable findings. We aim to contribute insights to the field of
multi-agent decision-making and explore the generalization of agents through
engineering efforts.
