A constant-factor approximation for stochastic Steiner forest
We consider the stochastic Steiner forest problem: suppose we were given a collection of Steiner forest instances, and were guaranteed that a random one of these instances would a...

Algorithms for a switch module routing problem
We consider a switch module routing problem for symmetric array FPGAs. The work is motivated by two applications. The rst is that of eciently evaluating switch module designs [8]...

A New Algorithm for Sampling CSP Solutions Uniformly at Random
The paper presents a method for generating solutions of a constraint satisfaction problem (CSP) uniformly at random. The main idea is to express the CSP as a factored probability d...
