Approximation Algorithms for the Loop Cutset Problem
We show how to nd a minimum weight loop cutset in a Bayesian network with high probability. Finding such a loop cutset is the rst step in the method of conditioning for inference....

Improved Primal-Dual Approximation Algorithm for the Connected Facility Location Problem
In the Connected Facility Location(ConFL) problem, we are given a graph G = (V, E) with nonnegative edge cost ce on the edges, a set of facilities F V , a set of demands, i.e., cl...
