Minimal Dominating Set

A minimal dominating set is a dominating set in a graph that is not a proper subset of any other dominating set.

Every minimum dominating set is a minimal dominating set, but the converse does not necessarily hold.

Minimal dominating sets can be used to compute the domatic number of a graph.

A dominating set is minimal dominating iff it is irredundant (Mynhardt and Roux 2020).

If a set is dominating and irredundant, it is maximal irredundant and minimal dominating (Mynhardt and Roux 2020).
