A Load Shedding Framework and Optimizations for M-way Windowed Stream Joins
Tuple dropping, though commonly used for load shedding in most stream operations, is inadequate for m-way, windowed stream joins. The join output rate can be overly reduced becaus...

Modelling Equidistant Frequency Permutation Arrays: An Application of Constraints to Mathematics
Equidistant Frequency Permutation Arrays are combinatorial objects of interest in coding theory. A frequency permutation array is a type of constant composition code in which each ...

Using Non-adaptive Group Testing to Construct Spy Agent Routes
We consider a network of remote agent platforms that are tested by roaming spy agents in order to identify those that are malicious, based on the outcome of each agent. It is show...

Towards Solving Many-Valued MaxSAT
We define the MaxSAT problem for many-valued CNF formulas, called many-valued MaxSAT, and establish its complexity class. We then describe a basic branch and bound algorithm for ...
