We study the Unsplittable Flow Problem (UFP) on a line graph, focusing on the long-standing open question of whether the problem is APX-hard. We describe a deterministic quasi-pol...

We study integrated prefetching and caching problems following the work of Cao et. al. [3] and Kimbrel and Karlin [13]. Cao et. al. and Kimbrel and Karlin gave approximation algor...
ABSTRACT∗ Arman Yousefi† Neal E. Young‡ Minimum-weight triangulation (MWT) is NP-hard. It has a polynomial-time constant-factor approximation algorithm, and a variety of e...
Abstract—Energy efficiency is critical for wireless sensor networks. The data gathering process must be carefully designed to conserve energy and extend the network lifetime. Fo...
We tackle the problem of non robustness of simulation and bisimulation when dealing with probabilistic processes. It is important to ignore tiny deviations in probabilities becaus...
