Workshop on
Ad Hoc Teamwork

Research on ad hoc teamwork has been around for at least 20 years, but it was first introduced as a formal challenge by Stone et al. in 2010. The challenge discussed in that paper is: 

    To create an autonomous agent that is able to efficiently and robustly collaborate with previously unknown teammates on tasks to which they are all individually capable of contributing as team members.

Since 2010, hundreds of papers that explicitly state ``ad hoc team'' or ``ad hoc teamwork'' have been published - 632 according to Google Scholar during the writing of this call - and much more address tightly connected challenges such as ``zero-shot'' or ``cold start'' teamwork. Moreover, much of the prevalent work on personalizing interactions with new human teammates can be viewed as ad-hoc teamwork.
