Stochastic Assignment with Expiration
… of our LP-based analysis by providing tight integrality gaps as well as worst-case instances. Returning to the capacitated problem, we provide another LP relaxation. We generalize our previous algorithms to evaluate their numerical performance on the harder, capacitated problem. We observe …

Unique Games Conjecture : the Boolean Hypercube and connections to graph lifts
… on the Hypercube. We construct an almost optimal integrality gap instance on the Hypercube for the Goemans-Williamson semidefinite program (SDP) for Max-2-LIN(\Z_2). We conjecture that augmenting the SDP with triangle inequalities makes the SDP exact upto constants on the Hypercube. We further …
