General Information

Prereq: Instructor's permission

Course description: Constraint satisfaction has emerged as a powerful approach to articulate and solve many problems in computer science, engineering, and management.  It is now the basis for new programming languages and innovative commercial systems for production scheduling, product configuration, personnel planning and timetabling, etc.  The goal of this course is to prepare students to conduct research in this area. The course will be intensive and will require thorough study of the theory and the algorithms, and a significant implementation effort. Students are expected to be self motivated, and demonstrate intellectual independence and collegial collaboration.
