Local Distance Antimagic Vertex Coloring of Graphs

Divya T, Devi Yamini S

A bijective function $f : V \to {1, 2, 3, ..., ∣ V ∣}$ is said to be a local distance antimagic labeling of a graph $G = (V, E)$ , if $w (u) \neq = w (v)$ for any two adjacent v…

Graceful coloring is computationally hard

Cyriac Antony, Laavanya D., Devi Yamini S

Given a (proper) vertex coloring $f$ of a graph $G$ , say $f : V (G) \to N$ , the difference edge labelling induced by $f$ is a function $h : E (G) \to N$ defin…

An Analysis of Graceful Coloring in a Specific r-Regular Graphs

Laavanya D., Devi Yamini S.

A graceful $l$ -coloring of a graph $G$ is a proper vertex coloring with $l$ colors which induces a proper edge coloring with at most $l - 1$ colors, where the color for an edge $ab$ …
