How to Play Unique Games on Expanders
In this paper, we improve a result by Arora, Khot, Kolla, Steurer, Tulsiani, and Vishnoi on solving the Unique Games problem on expanders. Given a (1-)-satisfiable instance of Uniq...

Lower Bounds for Smith's Rule in Stochastic Machine Scheduling
We consider the problem to minimize the weighted sum of completion times in nonpreemptive parallel machine scheduling. In a landmark paper from 1986, Kawaguchi and Kyan [5] showed ...

Strategic Multiway Cut and Multicut Games
We consider cut games where players want to cut themselves off from different parts of a network. These games arise when players want to secure themselves from areas of potential i...

Densest k-Subgraph Approximation on Intersection Graphs
We study approximation solutions for the densest k-subgraph problem (DS-k) on several classes of intersection graphs. We adopt the concept of -quasi elimination orders, introduced ...

An FPTAS for Flows over Time with Aggregate Arc Capacities
We study flows over time in networks with transit times on the arcs. Transit times describe how long it takes to traverse an arc. A flow over time specifies for each arc a time-dep...
