Multicast Advance Reservation RWA Heuristics in Wavelength-Routed Networks
In this paper we investigate the static multicast advance reservation (MCAR) problem for all-optical wavelengthrouted WDM networks. Advance reservation connection requests specify ...

Faster Approximate Distance Queries and Compact Routing in Sparse Graphs
A distance oracle is a compact representation of the shortest distance matrix of a graph. It can be queried to retrieve approximate distances and corresponding paths between any p...

Polynomial integrality gaps for strong SDP relaxations of Densest k-subgraph
The Densest k-subgraph problem (i.e. find a size k subgraph with maximum number of edges), is one of the notorious problems in approximation algorithms. There is a significant g...

Optimal Rewritings in Definitorially Complete Description Logics
In this paper, we revisit the problem of definitorial completeness, i.e., whether a given general TBox T in a description logic (DL) L can be rewritten to an acyclic TBox T in L . ...

A Complete Anytime Algorithm for Treewidth
In this paper, we present a Branch and Bound algorithm called QuickBB for computing the treewidth of an undirected graph. This algorithm performs a search in the space of perfect ...
