Signed mixed Roman domination numbers in graphs

Journal of Combinatorial Optimization, 2015
A signed mixed Roman dominating function (SMRDF) on a graph \(G=(V,E)\) is a function \(f:V\cup E\to\{-1,1,2\}\) satisfying the conditions (i) the sum of its function values over any closed mixed neighborhood of an element \(x\in V\cup E\) (the mixed closed neighborhood consists of \(x\) and the elements of \(V\cup E\) adjacent or incident to \(x\)) is
