AI seminar, March 5th, 2003: Mats Petter Pettersson, AI@CS Constraint Satisfaction under Uncertainty Abstract: Many real-world problems can be expressed as constraint satisfaction problems, CSPs. Stating a problem as a CSP is useful, as it makes possible the use of general solution methods that have been developed for this large class of problems. However, standard CSPs have a limited ability to express uncertainty and some kinds of preference among solutions. Fuzzy constraint satisfaction problems (FCSPs) are a generalization of CSPs, aiming to deal with these issues.
