The International Conference on Automated Planning and Scheduling came about from the merging of the International AI Planning and Scheduling Conference (AIPS) and the European Conference on Planning (ECP). Although the first conference under the new name was held in 2003, the organizers have honored the numbering of the two previous conferences. AAAI Press has published all of the previous ICAPS proceedings, and most of the prior AIPS proceedings, but none of the ECP proceedings.
