Time-and-Frequency-Hopping Optical Orthogonal Codes with Hierarchical Cross-Correlation Constraints for Service Differentiation
ā€” In this paper, we consider time-and-frequency hopping (TFH) codes for optical code-division multiple-access (OCDMA) networks. To support the differentiated service requirements...

Randomized Rounding for Routing and Covering Problems: Experiments and Improvements
We investigate how the recently developed different approaches to generate randomized roundings satisfying disjoint cardinality constraints behave when used in two classical algori...

Dependencies and separation of duty constraints in GTRBAC
A Generalized Temporal Role Based Access Control (GTRBAC) model that captures an exhaustive set of temporal constraint needs for access control has recently been proposed. GTRBACā...

Distance Estimates for Planning in the Discrete Belief Space
We present a general framework for studying heuristics for planning in the belief space. Earlier work has focused on giving implementations of heuristics that work well on benchma...

CP and IP approaches to cancer radiotherapy delivery optimization
Abstract. We consider the problem of decomposing an integer matrix into a positively weighted sum of binary matrices that have the consecutive-ones property. This problem is well-k...
