In this paper we investigate the effect of adding a failed literal detection method to the traditional unit clause propagation method in the look-ahead component of a modern SAT solver. Our investigation points out that, in all the SAT instances that we have tried, failed literal detection is bound to be ineffective, even assuming it has no overhead.
