Lightweight fault localization (LFL), which outputs a list of suspicious program entities in descending order based on their likelihood to be a root fault, is a popular method used by programmers to assist them in debugging. However, owing to the nature of program structures, it is impossible for LFL to always rank the root faulty program entity at the top of a ranking list. Recently, Xia et al. noted in their study that programmers inspect the first top-
