With a more careful approach, this trivial upper bound can be improved for certain natural restrictions of the CSP. In this paper we establish theoretical limits to such improvements, and draw a detailed landscape of the subexponential-time complexity of CSP.\n  We first establish relations between the subexponential-time complexity of CSP and that of other problems, including CNF-Sat.
