چکیده
The minimum vertex ranking spanning tree problem is to find a spanning tree of G whose vertex ranking is minimum. This problem is NP-hard and no polynomial time algorithm for solving it is known for non-trivial classes of graphs other than the class of interval graphs. This paper proposes a polynomial time algorithm for solving the minimum vertex ranking spanning tree problem on outerplanar graphs. key words: algorithm, vertex ranking, spanning tree, outerplanar graph

Minimum vertex ranking spanning tree problem for chordal and proper interval graphs
A vertex k-ranking of a simple graph is a coloring of its vertices with k colors in such a way that each path connecting two vertices of the same color contains a vertex with a bigger color. Consider the minimum vertex ranking spanning tree (MVRST) problem where the goal is to find a spanning tree of a given graph G which has a vertex ranking using the minimal number of colors over vertex ranki...
متن کاملThe minimum degree spanning tree problem on directed acyclic graphs
The minimum degree spanning tree problem has been studied extensively. In this paper, we present a polynomial time algorithm for the minimum degree spanning tree problem on directed acyclic graphs. The algorithm starts with an arbitrary spanning tree, and iteratively reduces the number of vertices of maximum degree. We can prove the algorithm must reduce a vertex of the maximum degree for each ...
متن کاملTree t-spanners in outerplanar graphs via supply demand partition
A tree t-spanner of an unweighted graph G is a spanning tree T such that for every two vertices their distance in T is at most t times their distance in G. Given an unweighted graph G and a positive integer t as input, the tree t-spanner problem is to compute a tree t-spanner of G if one exists. This decision problem is known to be NP-complete even in the restricted class of unweighted planar g...
متن کاملOn Minimum Average Stretch Spanning Trees in Polygonal 2-Trees
A spanning tree of an unweighted graph is a minimum average stretch spanning tree if it minimizes the ratio of sum of the distances in the tree between the end vertices of the graph edges and the number of graph edges. We consider the problem of computing a minimum average stretch spanning tree in polygonal 2-trees, a super class of 2-connected outerplanar graphs. For a polygonal 2-tree on n ve...
متن کاملA Simple Cubic Algorithm for Computing Minimum Height Elimination Trees for Interval Graphs
In parallel sparse Cholesky factorization, nding elimination order-ings that produce elimination trees of low height is important. The problem of nding the minimum elimination tree height for a graph is NP-hard for general graphs. This problem is equivalent to the problem of nding the vertex ranking number of a graph. The problem can be solved in polynomial time for special classes of graphs. A...
