We introduce the following combinatorial optimization problem: Given a connected graph G, find a spanning tree T of G with the smallest number of branchv ertices (vertices of degree 3 or more in T). The problem is motivated by new technologies in the realm of optical networks. We investigate algorithmic and combinatorial aspects of the problem.

Abstract
We introduce the following combinatorial optimization problem: Given a connected graph G, find a spanning tree T of G with the smallest number of branchv ertices (vertices of degree 3 or more in T). The problem is motivated by new technologies in the realm of optical networks. We investigate algorithmic and combinatorial aspects of the problem.File in questo prodotto:
