Strong Geodetic Number of Complete Bipartite Graphs and of Graphs with Specified Diameter

Original Paper


The strong geodetic problem is a recent variation of the classical geodetic problem. For a graph G, its strong geodetic number \({{\mathrm{sg}}}(G)\) is the cardinality of a smallest vertex subset S, such that each vertex of G lies on one fixed shortest path between a pair of vertices from S. In this paper, some general properties of the strong geodetic problem are studied, especially in connection with the diameter of a graph. The problem is also solved for balanced complete bipartite graphs.
