The 0-1 Multidimensional Knapsack Problem (0-1 MKP) is a well-
known (and strongly N P -hard) combinatorial optimization problem
with many applications. Up to now, the ma jority of upper bounding
techniques for the 0-1 MKP have been based on Lagrangian or surro-
gate relaxation. We show that good upper bounds can be obtained by
a cutting plane method based on lifted cover inequalities (LCIs). As
well as using traditional LCIs, we use some new ‘global’ LCIs, which
take the whole constraint matrix into account.
