Dynamic approach to k-forcing

Published 29 May 2014 in math.CO | (1405.7573v1)

Abstract: The k-forcing number of a graph is a generalization of the zero forcing number. In this note, we give a greedy algorithm to approximate the k-forcing number of a graph. Using this dynamic approach, we give corollaries which improve upon two theorems from a paper of Amos, Caro, Davila and Pepper [2], while also answering an open problem posed by Meyer [9].
