IP-Subnet Aware Routing in WDM Mesh Networks
Abstract— We explore the problem of routing bandwidth guaranteed paths in wavelength-routed, WDM optical mesh networks. A WDM mesh network offers great flexibility in dynamicall...

If NP Languages are Hard on the Worst-Case Then It is Easy to Find Their Hard Instances
We prove that if NP ⊆ BPP, i.e., if SAT is worst-case hard, then for every probabilistic polynomial-time algorithm trying to decide SAT, there exists some polynomially samplable ...

Approximating the Expressive Power of Logics in Finite Models
Abstract. We present a probability logic (essentially a first order language extended with quantifiers that count the fraction of elements in a model that satisfy a first order ...

Non-cooperative multicast and facility location games
We consider a multicast game with selfish non-cooperative players. There is a special source node and each player is interested in connecting to the source by making a routing de...
