WebFinally, we show that the problem of computing the total weak Roman domination number of a graph is NP-hard. Given a graph G = ( V , E ) , a function f : V → { 0 , 1 , 2 , ⋯ } is said to be a total dominating function if ∑ u ∈ N ( v ) f ( u ) > 0 for every v ∈ V , where N ( v ) denotes the open neighbourhood of v. ...

WebMore formally, a problem is NP-hard if and only if, for any problem 0in NP, there is a polynomial-time Turing reduction from 0to —a Turing reduction just means a reduction … WebAs shown in , the general optimization problem of computing the total domination number of a graph with no isolated vertex is NP-hard. Therefore, by Theorem 6 (considering the case γ ( H ) ≥ 2 ) we immediately obtain the analogous result for the strongly total Roman domination number.
