Deskripsi

Let   be  a graph with vertex set  and edge set . If  is a set of vertices of , then  is the union of all sets  for  If then  is a geodetic set for . The geodetic number  is the minimum cardinality of a geodetic set. A geodetic set is called co- even geodetic set if the degree of vertex  is even number for all . The cardinality of a smallest co-even geodetic set of , denoted by is the co- even geodetic number of . In this paper, we find the co- even geodetic number of certain graphs and complement graphs
