On the Impact of Local Taxes in a Set Cover Game
Given a collection C of weighted subsets of a ground set E, the set cover problem is to find a minimum weight subset of C which covers all elements of E. We study a strategic game ...

Efficient Compression from Non-ergodic Sources with Genetic Algorithms
Several lossless data compression schemes have been proposed over the past years. Since Shannon developed information theory in his seminal paper, however, the problem of data com...

Two-Hop Virtual Path Layout in Tori
We consider a problem motivated by the design of ATM (Asynchronous Transfer Mode) networks. Given a physical network and an All-to-All traffic, the problem consists in designing a...

Optimal Wavelength-routed Multicasting
Motivated by wavelength division multiplexing in all-optical networks, we consider the problem of finding a set of paths from a fixed source to a multiset of destinations, which c...

Asymptotic enumeration of 2-covers and line graphs
A 2-cover is a multiset of subsets of [n] := {1, 2, . . . , n} such that each element of [n] lies in exactly two of the subsets. A 2-cover is called proper if all of the subsets o...
