Abstract. In this paper we study dualities of graphs and, more generally, relational structures with respect to full homomorphisms, that is, mappings that are both edge- and non-ed...
Many real-life Constraint Satisfaction Problems (CSPs) involve some constraints similar to the alldifferent constraints. These constraints are called constraints of difference. Th...
This paper concerns the specialization of arcconsistency algorithms for constraint satisfaction in the management of quantitative temporal constraint networks. Attention is devote...
We consider a broadcast channel with multiple antennas at the base station and single-antenna receivers, and we study transceiver design with Quality of Service (QoS) requirements...
Linear equality and inequality constraints arise naturally in specifying many aspects of user interfaces, such as requiring that one window be to the left of another, requiring tha...
