As demonstrated by work : in scheduling, rostering, vehicle routing, and other problems, : constraint programming (CP) provides a powerful means for doing : successful integrations of this kind. Nowadays, most industrial CP : tools and systems have integrated efficient special purpose techniques : from OR for improving problem solving facilities. : : In February 1999, the Universities of Bologna and Ferrara (Italy) : organized the workshop CP-AI-OR'99 and brought together about 60 : researchers from AI and OR to discuss integration issues. In order to : continue this successful event, the second workshop on integration of : AI and OR techniques in CP will be held at the University of Paderborn : (Germany) from March 8-10, 2000. : : The aim of the workshop is to bring together interested researchers : from AI and OR and to make this the major forum for exchanging ideas : and methodologies from both fields. During the workshop ample time will : be allocated for discussion. For instance, a panel discussion with the : title "Hybrid AI/CP/OR methods: What are the next challenges?" is : planned during the workshop. : : This year a special session will focus on airline planning and : scheduling problems, since the workshop is organized by the European : research project PARROT (Parallel Crew Rostering with CP and OR : techniques). : : INVITED PRESENTATIONS : : * Peter Brucker, University of Osnabrueck : Scheduling and Constraint Propagation : : * Pascal van Hentenryck, University of Louvain : OPL: A modeling language for mathematical and constraint : programming : : * George Nemhauser, Georgia Institute of Technology : Optimization in Airline Scheduling : : ACCEPTED PAPERS : : * B.

It is a city with a long : and rich history, dating back 1200 years. : : In recent times, the development of Nixdorf computers has led to : intense local activity in computer science. The Paderborn Center of : Parallel Computing (PC2), with research focused on parallelism in : operations research, applied mathematics, and virtual reality, : enhances this activity. In addition, the world's largest computer : museum is located next door to the workshop site. : : The Paderborn airport (PAD) can be easily reached from Frankfurt, : Amsterdam, Munich, Paris, and London. : : SOCIAL EVENTS : : On Wednesday a reception will be held in the Hall of Mirrors of the : Renaissance chateau Schloss Neuhaus, built in the 16th-18th centuries : and which long served the Paderborn princebishops as a residence. : The chateau is in walking distance of the conference site. : : On Thursday there will be a banquet dinner. The lunches will be served : at Cafetria of the Heinz Nixdorf Museum Forum (next door to the workshop : : site), which is the world's largest computer museum.
