ECP is a major international conference for presentation of new research in AI Planning and Scheduling, and a fruitful opportunity for contact and cross-fertilization among the different "souls" in the field. It has taken place in Europe every other year since 1991. It has evolved very quickly from a restricted workshop mainly devoted to the presentation of European research to a well established conference devoted to the presentation of rigorous and innovative research results from the international community. The sixth ECP conference will take place in the center of historical Toledo, the very well known old Spanish city, crossing of many different cultures (Arabic, Jewish and Christian). ECP-01 would like to follow its established scientific tradition, also including events that highlight specific aspects of planning and scheduling research in the new millennium.
