Constraint Processing Lab

The Constraint Processing Lab, at the University of Regina, is a centre for research on the theoretical and practical aspects of constraint solving and optimization. This Lab is funded by NSERC Discovery and Engage Grants. The lab is located in Room 308.19 of the College West Building and Room 129.9 in the Classroom Building.
