An Exponential Time 2-Approximation Algorithm for Bandwidth
The bandwidth of a graph G on n vertices is the minimum b such that the vertices of G can be labeled from 1 to n such that the labels of every pair of adjacent vertices differ by ...

Brief announcement: exponential speed-up of local algorithms using non-local communication
We demonstrate how to leverage a system’s capability for allto-all communication to achieve an exponential speed-up of local algorithms despite bandwidth and memory restrictions...

Approximation algorithms for combinatorial auctions with complement-free bidders
We exhibit three approximation algorithms for the allocation problem in combinatorial auctions with complement free bidders. The running time of these algorithms is polynomial in ...
