In fact, Vizing's proof implies an O(nm) time algorithm with β¬ Ο© 1 colors for the edge-coloring problem. However, Holyer has shown that deciding whether a graph requires β¬ or β¬ Ο© 1 colors is NP-complete [10]. For a multigraph G, Shannon showed that Π(G) Υ 3β¬/2 [16]. A number of parallel algorithms
## Abstract We describe two algorithms for the parallel calculation of a CHARMmβlike force field in macromolecules. For a molecule with a given number of atoms, we show that there is an optimal number of processors leading to a minimum computation time. At the optimum, both the number of processors
