Resumen de No advantageous merging in minimum cost spanning tree problems

María Gómez Rúa , Juan José Vidal Puga

• In the context of cost sharing in minimum cost spanning tree problems, we introduce a property called No Advantageous Merging. This property implies that no group of agents can be better o.. claiming to be a single node. We show that the sharing rule that assigns to each agent his own connection cost (the Bird rule) satisfies this property.

  Moreover, we provide a characterization of the Bird rule using No Advantageous Merging.
