Abstract. In this article we report our experience on building a contextual application with two different middlewares: the Context Toolkit from Georgia Tech and the Coordination L...
Several combinatorial optimization problems choose elements to minimize the total cost of constructing a feasible solution that satisfies requirements of clients. In the STEINER T...
The application designers can usually define their own "virtual environments" by selecting the appropriate computing resources required, or reuse and compose existing en...
We develop a simple and practical exact algorithm for the problem of locating p facilities and assigning clients7 to them within capacity restrictions in order to minimize the max...
The p-center problem is to locate p facilities in a network of n demand points so as to minimize the longest distance between a demand point and its nearest facility. We consider ...
