1998
Information and Computation
Preserved Fulltext
This paper studies an optimization problem that arises in the context of distributed resource allocation: Given a conflict graph that represents the competition of processors over resources, we seek an ...
For some instances of the resource allocation problem, such as the Dining Philosophers, an efficient solution requires edge coloring of the conflict graph. ...
We would like to thank Hagit Attiya for many stimulating discussions on this paper, and Sara Nicoloso for introducing to us various applications of the chromatic sum problem. ...
