In this paper a new upper bound for the feedback set of cubic graphs is obtained. This result answers a question posed by Speckenmeyer (1986, 1988) in the field of feedback vertex set and improves several former results due to Bondy et al. (1987). Also this new bound is sharp in some cases.
A defining set (sf cute-x coloring) of a graph G is a set of vertices S with an assignment of colors to its elements which has a unique completion to a proper coloring of G. We define a minimal d&kg set to be a defining set which does not properly contain another defining set. If G is a uniquely ver
