What is a grapher in math?

(ɡrɑːf; ɡræf) n. 1. ( Mathematics) Also called: chart a drawing depicting the relation between certain sets of numbers or quantities by means of a series of dots, lines, etc, plotted with reference to a set of axes. See also bar graph.

What is harmonious labeling?

A harmonious labeling on a graph G is an injection from. the vertices of G to the group of integers modulo k, where k. is the number of edges of G, that induces a bijection between. the edges of G and the numbers modulo k by taking the edge. label for an edge (x, y) to be the sum of the labels of the.

Who introduced Magic labeling?

Sedláček [9] introduced the concept of magic labeling. Suppose that is a graph with edges. We shall say that is magic if the edges of can be labeled by the numbers 1 , 2 , 3 , … , q so that the sum of labels of all the edges incident with any vertex is the same.

What is edge label?

A good edge-labelling of a graph is a labelling of its edges such that, for any ordered pair of vertices , there do not exist two paths from to with increasing labels. This notion was introduced by Bermond et al. (2009) [2] to solve wavelength assignment problems for specific categories of graphs.

What is grapher used for?
