An Algorithm for Covering the Vertices of a Directed Graph

67

Abstract

The article presents an algorithm for solving the applied problem of assigning and moving locomotives, based on the solution of the graph–theoretic problem of covering the vertices of a directed graph with a set of oriented paths. A detailed example is given for an algorithm for covering the vertices of a directed graph with a set of maximal paths.
