The COIN international workshop series has started in 2006. The ideia is to organize the workshop colocated to major AI conferences with interests in the topics of agents coordination, organizations, institutions and norms, like AAMAS, IJCAI, ECAI etc. From 2020, the acronym was updated to COINE, since ethics for governance of MAS became a major issue of interest to the workshop.
