Tight Approximation Results for General Covering Integer Programs

  title={Tight Approximation Results for General Covering Integer Programs},
  author={Stavros G. Kolliopoulos and Neal E. Young},
In this paper we study approximation algorithms for solving a generalcovering integer program.An n-vector x of nonnegative integers is sought, which minimizes T x; subject toAx b; x d: The entries of A; b; are nonnegative. Letm be the number of rows of A: Covering problems have been heavily studied in combinatorial optimization. We focus on the effect of the multiplicity constraints,x d; on approximability. Two longstanding open questions remain for this general formulation with upper bounds on… CONTINUE READING
