Abstract:
The paper is concerned with a possible statement of the problem of locating in a specified graph those parts which are more «saturated» than any others with «small» graphs of the same type. With this formulation the solution is obtained by assembling a monotonic system of structural elements of the graphs (arcs or vertices). The sequence of obtaining a monotonic system from a specified graph is given in a general form and the necessary design is illustrated with examples. The article is an extensition of Refs. [1, 2] and illustrates the tools reported there for locating extremal subsystems for solution of certain problems arising in tournaments, acyclic graphs, in nonoriented and oriented trees.
