Many combinatorial problems can be efficiently solved for seriesαparallel multigraphs. However, the edge-coloring problem of finding the minimum number of colors required for edge-coloring given graphs is one of a few well-known combinatorial problems for which no efficient algorithms have been obta

β¦ Synopsis
We consider the problem of efficient coloring of the edges of a so-called binomial tree T, i.e. acyclic graph containing two kinds of edges: those which must have a single color and those which are to be colored with L consecutive colors, where L is an arbitrary integer greater than 1. We give an O(n) time algorithm for optimal coloring of such a tree, where n is the number of vertices of T. Also, we give simple bounds on the chromatic index of T and a division of all binomial trees into two classes depending on their chromaticity.

Given a tree containing n vertices, consider the sum of the distance between all Ε½ . vertices and a k-leaf subtree subtree which contains exactly k leaves . A k-tree core is a k-leaf subtree which minimizes the sum of the distances. In this paper, we propose a linear time algorithm for finding a k-t
## Abstract The broadcast domination problem is a variant of the classical minimum dominating set problem in which a transmitter of power __p__ at vertex __v__ is capable of dominating (broadcasting to) all vertices within distance __p__ from __v__. Our goal is to assign a broadcast power __f__(__v
In this paper we consider the problem of determining whether a given colored graph can be triangulated, such that no edges between vertices of the same color are added. This problem originated from the perfect phylogeny problem from molecular biology and is strongly related with the problem of recog
A distance-hereditary graph is a connected graph in which every induced path is isometric, i.e., the distance of any two vertices in an induced path equals their distance in the graph. We present a linear time labeling algorithm for the minimum cardinality connected r-dominating set and Steiner tree
