Cost-Based Arc Consistency for Global Cardinality Constraints
A global cardinality constraint (gcc) is specified in terms of a set of variables X = {x1, ..., xp} which take their values in a subset of V = {v1, ..., vd}. It constrains the numb...

Time constraints in mixed multi-unit combinatorial auctions
We extend the framework of mixed multi-unit combinatorial auctions to include time constraints, present an expressive bidding language, and show how to solve the winner determinati...

On a class of time varying shapers with application to the renegotiable variable bit rate service
A shaper is a system that stores incoming bits in a bu er and delivers them as early as possible, while forcing the output to be constrained with a given arrival curve. A shaper i...

Communication Limits with Low Precision Analog-to-Digital Conversion at the Receiver
— We examine the Shannon limits of communication systems when the precision of the analog-to-digital conversion (ADC) at the receiver is constrained. ADC is costly and powerhungr...
