Minimal dominating sets in interval graphs and trees
We show that interval graphs on n vertices have at most 3 ≈ 1.4422 minimal dominating sets, and that these can be enumerated in time O∗(3n/3). As there are examples of interval graphs that actually have 3 minimal dominating sets, our bound is tight. We show that the same upper bound holds also for trees, i.e. trees on n vertices have at most 3 ≈ 1.4422 minimal dominating sets. The previous best...
متن کاملMinimal 2-dominating sets in trees
We provide an algorithm for listing all minimal 2-dominating sets of a tree of order n in time O(1.3248n). This implies that every tree has at most 1.3248n minimal 2-dominating sets. We also show that this bound is tight.
متن کاملMinimal Double Dominating Sets in Trees
We provide an algorithm for listing all minimal double dominating sets of a tree of order n in time O(1.3248). This implies that every tree has at most 1.3248 minimal double dominating sets. We also show that this bound is tight.
متن کاملTrees having many minimal dominating sets
We disprove a conjecture by Skupień that every tree of order n has at most 2 minimal dominating sets. We construct a family of trees of both parities of the order for which the number of minimal dominating sets exceeds 1.4167. We also provide an algorithm for listing all minimal dominating sets of a tree in time O(1.4656). This implies that every tree has at most 1.4656 minimal dominating sets.
متن کاملminimal, vertex minimal and commonality minimal cn-dominating graphs
we define minimal cn-dominating graph $mathbf {mcn}(g)$, commonality minimal cn-dominating graph $mathbf {cmcn}(g)$ and vertex minimal cn-dominating graph $mathbf {m_{v}cn}(g)$, characterizations are given for graph $g$ for which the newly defined graphs are connected. further serval new results are developed relating to these graphs.
