A simple randomized parallel algorithm for maximal ƒ-matchings

For many problems the main advantage of randomization is gaining simplicity. This happens in the computation of maximal matchings in graphs. It is shown that a known and quite simple randomized algorithm for maximal matchings has a natural extension to the so called f-matchings (which are generaliza...

Zusammenfassung:For many problems the main advantage of randomization is gaining simplicity. This happens in the computation of maximal matchings in graphs. It is shown that a known and quite simple randomized algorithm for maximal matchings has a natural extension to the so called f-matchings (which are generalizations of matchings). In particular, each (usual) matching is a 1-matching. The whole structure of the randomized algorithm is very simple; it finds a partial f-matching F, deletes the edges of F, updates capacities and then removes edges incident to vertices with actual capacity equal to zero. This continues until the graph is empty.
