Graph hard problems
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. WebThe problem for graphs is NP-complete if the edge lengths are assumed integers. The problem for points on the plane is NP-complete with the discretized Euclidean metric …
