Polynomial integrality gaps for strong SDP relaxations of Densest k-subgraph
The Densest k-subgraph problem (i.e. find a size k subgraph with maximum number of edges), is one of the notorious problems in approximation algorithms. There is a significant g...

A Primal-Dual Algorithm for Computing Fisher Equilibrium in the Absence of Gross Substitutability Property
Abstract. We provide the first strongly polynomial time exact combinatorial algorithm to compute Fisher equilibrium for the case when utility functions do not satisfy the Gross su...

Analyzing Nonblocking Switching Networks using Linear Programming (Duality)
Abstract—The main task in analyzing a switching network design (including circuit-, multirate-, and photonic-switching) is to determine the minimum number of some switching compo...

A tight bound on remote reference time complexity of mutual exclusion in the read-modify-write model
In distributed shared memory multiprocessors, remote memory references generate processor-to-memory traffic, which may result in a bottleneck. It is therefore important to design ...
