A New Modal Approach to the Logic of Intervals
In Artificial Intelligence there is a need for reasoning about continuous processes, where assertions refer to time intervals rather than time points. Taking our lead from van Ben...

A characterization of uniquely vertex colorable graphs using minimal defining sets
A defining set (of vertex coloring) of a graph G is a set of vertices S with an assignment of colors to its elements which has a unique completion to a proper coloring of G. We de...

Characterization of Networks Supporting Multi-dimensional Linear Interval Routing Schemes
An Interval Routing Scheme (IRS) is a well-known, space efficient routing strategy for routing messages in a distributed network. In this scheme, each node of the network is assig...

On the Approximability of Average Completion Time Scheduling under Precedence Constraints
Abstract. We consider the scheduling problem of minimizing the average weighted job completion time on a single machine under precedence constraints. We show that this problem with...
