Bounds on the restrained Roman domination number of a graph

A {\em Roman dominating function} on a graph $G$ is a function‎ ‎$f:V(G)\rightarrow \{0,1,2\}$ satisfying the condition that every‎ ‎vertex $u$ for which $f(u) = 0$ is adjacent to at least one vertex‎ ‎$v$ for which $f(v) =2$‎. ‎A {\em restrained Roman dominating}‎ ‎function $f$ is a Roman domin...
