Approximating the minimum directed tree cover
Given a directed graph G with non negative cost on the arcs, a directed tree cover of G is a directed tree such that either head or tail (or both of them) of every arc in G is touc...

Approximating the k-traveling repairman problem with repairtimes
Given an undirected graph G = (V,E) and a source vertex s ∈ V , the k-traveling repairman (KTR) problem, also known as the minimum latency problem, asks for k tours, each starti...

A Polynomial Time Algorithm for Minimum Cycle Basis in Directed Graphs
Abstract. We consider the problem of computing a minimum cycle basis in a directed graph G with m arcs and n vertices. The arcs of G have non-negative weights assigned to them. We ...

Directionality As Needed - Achieving Connectivity in Wireless Mesh Networks
: We study how to achieve a desired connectivity in a wireless mesh network using beamforming antennas. We show that there is no unique solution to this problem. Then, we propose a...
