Sometimes merely randomization is not enough to show what we want. A common strategy is then to alter the instance we construct via randomness. For example, if the expectation of the parameter X of a random object is EX, then we have an instance with parameter ≤ EX. However, what we are after might be a “perfect” object with X = 0. Thus, what we do is to “correct bad properties”. Once again, th...

We present a counterexample to a lower bound for the power domination number given in Liao, Power domination with bounded time constraints, J. Comb. Optim. 31 (2016): 725–742. We also define the power propagation time, using the power domination propagation ideas in Liao and the (zero forcing) propagation time in Hogben et al, Propagation time for zero forcing on a graph, Discrete Appl. Math., ...
