Constraint programming is like an octopus spreading its tentacles into databases, operations examine, synthetic intelligence, and plenty of different parts. the idea that of constraint programming used to be brought in synthetic intelligence and photos within the Sixties and Seventies. Now the comparable ideas are used and studied in lots of fields of computing. diverse features of constraint processing are investigated in theoretical machine technological know-how, good judgment programming, wisdom illustration, operations examine, and comparable software domain names. Constraint programming has been incorporated within the lists of comparable issues of many meetings. however, simply in 1993 have been the 1st boards held, dedicated as a complete to this box of data. those have been the 1st Workshop on ideas and perform of Constraint Programming (PPCP'93) which used to be held in Newport, Rhode Island, united states, April 28-30, the foreign Workshop on Constraint Processing (at CSAM'93) held in St. Petersburg, Russia, July 20-21, and the NATO complex examine Institute (NATO AS!) on Constraint Programming held in Parnu, Estonia, August 13-24. NATO A Sis are aimed to be faculties bringing jointly best researchers and practitioners from and academia in a few zone of data to supply a concise photo of the paintings performed and effects bought through diverse teams. this is often meant for dissemination of complex wisdom no longer but taught on a regular basis in of recent themes college. in spite of the fact that, ASis also needs to motivate the advent into collage curricula in addition to foster overseas clinical contacts.
