We apply a linearization technique for nonconvex quadratic problems wi
th box constraints. We show that cutting plane algorithms can be desig
ned to solve the equivalent problems which minimize a linear function
over a convex region. We propose several classes of valid inequalities
of the convex region which are closely related to the Boolean quadric
polytope. We also describe heuristic procedures for generating cuttin
g planes. Results of preliminary computational experiments show that o
ur inequalities generate a polytope which is a fairly tight approximat
ion of the convex region.
