Approximating Independent Set in Semi-Random Graphs
We present an algorithm for the independent set problem on semi-random graphs, which are generated as follows: An adversary chooses an n-vertex graph, and then each edge is flipp...

The Directed Minimum Latency Problem
We study the directed minimum latency problem: given an n-vertex asymmetric metric (V, d) with a root vertex r V , find a spanning path originating at r that minimizes the sum of...

Bayesian framework and message passing for joint support and signal recovery of approximately sparse signals
In this paper, we develop a low-complexity message passing algorithm for joint support and signal recovery of approximately sparse signals. The problem of recovery of strictly spa...
