On the Complexity of Join Predicates
We consider the complexity of join problems, focusing on equijoins, spatial-overlap joins, and set-containment joins. We use a graph pebbling model to characterize these joins com...

A Dynamic Graph Algorithm for the Highly Dynamic Network Problem
A recent flooding algorithm [1] guaranteed correctness for networks with dynamic edges and fixed nodes. The algorithm provided a partial answer to the highly dynamic network (HDN)...

Algorithmic aspects of topology control problems for ad hoc networks
Topology control problems are concerned with the assignment of power values to the nodes of an ad hoc network so that the power assignment leads to a graph topology satisfying som...

Retiming with Interconnect and Gate Delay
In this paper, we study the problem of retiming of sequential circuits with both interconnect and gate delay. Most retiming algorithms have assumed ideal conditions for the non-lo...
