The ICLP’09 program will include seven workshops. They are perhaps the best places for the presentation of preliminary work, novel ideas, and new open problems to a wide and interested audience. Workshops also provide a venue for presenting specialized topics and opportunities for intensive discussions and project collaboration in any areas related to logic programming, including cross-disciplinary areas:

  1. Workshop on Answer Set Programming and Other Computing Paradigms (ASPOCP)
  2. Workshop on Constraint Handling Rules (CHR)
  3. Colloquium on Implementation of Constraint and LOgic Programming Systems (CICLOPS)
  4. Workshop on (Constraint) Logic Programming and Software Engineering (CLPSE)
  5. Workshop on Commercial Users of Logic Programming (CULP)
  6. Workshop on ISO Prolog — WG17
  7. Workshop on Logic-based methods in Programming Environments (WLPE)


Located at the base of the beautiful San Gabriel Mountains, Pasadena’s central location serves as a gateway to all that Southern California has to offer. Pasadena itself offers a surprising combination of sophisticated charm, culture, history, and fun. Pasadena is Southern California’s premier dining and entertainment destination, with over 500 restaurants. The city consists of several districts, including “Old Town”, an historic 22-block area, offering more than 120 specialty shops, retail stores and boutiques, 80 restaurants, and an array of entertainment opportunities. Several world-class museums, including the Huntington Library and Art Gallery, the Norton Simon Museum, and the Pacific Asia Museum are located here, as well as several extensive botanical gardens at the Los Angeles County Arboretum, the Huntington Library, and Descanso Gardens, reflecting Pasadena’s association with the “Rose”. The city has a rich architectural heritage, which includes an unusual concentration and diversity of landmark-quality buildings dating from the late 1880s. Be sure to visit the recently renovated City Hall — only steps away from the Pasadena Convention Center — an exquisite 1927 landmark exhibiting Italian Renaissance and Spanish influences. Pasadena has a lively arts scene, with such diverse offerings as the famous Pasadena Playhouse or Ice House Comedy Club, which has played host to the comedic talents of Steve Martin, Robin Williams, and Lily Tomlin. Pasadena has long been considered a premier center for science and technology, serving as the home to the California Institute of Technology and the Jet Propulsion Laboratory, as well as several high-profile industry partner
