Compact roundtrip routing with topology-independent node names
This paper presents compact roundtrip routing schemes with local tables of size ˜O( √ n) and stretch 6 for any directed network with arbitrary edge weights; and with local tabl...

Combining Tree Partitioning, Precedence, and Incomparability Constraints
The tree constraint partitions a directed graph into node-disjoint trees. In many practical applications that involve such a partition, there exist side constraints specifying requ...

A Primal Branch-and-Cut Algorithm for the Degree-Constrained Minimum Spanning Tree Problem
The degree-constrained minimum spanning tree (DCMST) is relevant in the design of networks. It consists of finding a spanning tree whose nodes do not exceed a given maximum degree...
