Oct 2, 2020 · Consider a vertex-colored graph G = ( V , E ) . We say an edge is happy if its endpoints have the same color (otherwise, the edge is unhappy).

Aug 13, 2017 · A vertex v is said to be happy with respect to c if c(v) = c(u) for all neighbors u of v. Further, an edge (u,v) is happy if c(u) = c(v).

A vertex $v$ is said to be happy with respect to $c$ if $c(v) = c(u)$ for all neighbors $u$ of $v$. Further, an edge $(u,v)$ is happy if $c(u) = c(v)$.

In a vertex-colored graph, an edge is happy if its endpoints have the same color. Similarly, a vertex is happy if all its incident edges are happy.

In a vertex-colored graph, an edge is happy if its endpoints have the same color. Similarly, a vertex is happy if all its incident edges are happy.
