Greedy Approximation via Duality for Packing, Combinatorial Auctions and Routing
We study simple greedy approximation algorithms for general class of integer packing problems. We provide a novel analysis based on the duality theory of linear programming. This e...

Characteristic Patterns for LTL
We give a new characterization of those languages that are definable in fragments of LTL where the nesting depths of X and U modalities are bounded by given constants. This brings...

An autonomic failure-detection algorithm
Designs for distributed systems must consider the possibility that failures will arise and must adopt specific failure detection strategies. We describe and analyze a self-regulat...

Box consistency through adaptive shaving
The canonical algorithm to enforce box consistency over a constraint relies on a dichotomic process to isolate the leftmost and rightmost solutions. We identify some weaknesses of...
