On Pathos Semitotal and Total Block Graph of a Tree [PDF]

open access: yes, 2011
The concept of pathos of a graph G was introduced by Harary [2], as a collection of minimum number of line disjoint open paths whose union is G. The path number of a graph G is the number of paths in pathos.

Self-transformation of trees with a bounded degree of vertices to minimize or maximize the Wiener index

open access: yesТруды Института системного программирования РАН, 2019
We consider a distributed network whose communication graph is a non-oriented tree. It is assumed that the network itself can change its topology. For this, an extremely local atomic transformation is proposed - the addition of an edge connecting the ...
