GRAF AJAIB TOTAL
Abstract: A total labeling of
a graph with p vertices and q edges is dened as a one-to-one map taking the
vertices and edges onto the integers 1; 2; ; p + q. Such a labeling is vertex magic if
the sum of the label on a vertex and the labels on its incident edges is a
constant independent of the choice of vertex, and edge magic if the sum of an
edge label and the labels of the endpoints of the edge is constant. In this
paper we examine graphs possessing a labeling that is simultaneously vertex
magic and edge magic. Such graphs appear to be rare.
