Calculating lower bounds for caching problems
We present a general method for computing lower bounds for various caching problems. We apply the method to two well known problems, companion caching and weighted caching. For we...

An Improved Hybrid Model for the Generic Hoist Scheduling Problem
Abstract. The generic hoist scheduling problem is NP-hard and arises from automated manufacturing lines. In recent work using the constraint logic programming (CLP) formalism, a un...

Multiple-Resource Periodic Scheduling Problem: how much fairness is necessary?
The Pfair algorithms are optimal for independent periodic real-time tasks executing on a multiple-resource system, however, they incur a high scheduling overhead by making schedul...
