The Power of Priority Algorithms for Facility Location and Set Cover
We apply and extend the priority algorithm framework introduced by Borodin, Nielsen, and Rackoff to define "greedy-like" algorithms for the (uncapacitated) facility locat...

Covering Trees and Lower-bounds on Quadratic Assignment
Many computer vision problems involving feature correspondence among images can be formulated as an assignment problem with a quadratic cost function. Such problems are computatio...

Minimum-Energy Broadcast and disk cover in grid wireless networks
The Minimum-Energy Broadcast problem is to assign a transmission range to every station of an ad-hoc wireless networks so that (i) a given source station is allowed to perform bro...

Constraint Bipartite Vertex Cover: Simpler Exact Algorithms and Implementations
constraint bipartite vertex cover is a graph-theoretical formalization of the spare allocation problem for reconfigurable arrays. We report on an implementation of a parameterized ...

The complexity of cover inequality separation
Crowder et al. (Oper. Res. 31 (1983) 803–834) conjectured that the separation problem for cover inequalities for binary integer programs is polynomially solvable. We show that t...
