We show that it is NP-hard to determine if a cubic graph G is l-tough. We then use this result to show that for any integer t > 1, it is NP-hard to determine if a 3 t-regular graph is t-tough. We conclude with some remarks concerning the complexity of recognizing certain subclasses of tough graphs.

Let G = (V; E) be a simple graph. The NON-PLANAR DELETION problem consists in ΓΏnding a smallest subset E β E such that H =(V; E\E ) is a planar graph. The SPLITTING NUMBER problem consists in ΓΏnding the smallest integer k ΒΏ 0, such that a planar graph H can be deΓΏned from G by k vertex splitting ope
