A Filtering Algorithm for Constraints of Difference in CSPs
Many real-life Constraint Satisfaction Problems (CSPs) involve some constraints similar to the alldifferent constraints. These constraints are called constraints of difference. Th...

Time-and-Frequency-Hopping Optical Orthogonal Codes with Hierarchical Cross-Correlation Constraints for Service Differentiation
— 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...
