Counterexample-Guided Focus
The automated inference of quantified invariants is considered one of the next challenges in software verification. The question of the right precision-efficiency tradeoff for the corresponding program analyses here boils down to the question of the right treatment of disjunction below and above the universal quantifier. In the closely related setting of shape analysis one uses the focus operator in order to adapt the treatment of disjunction (and thus the efficiency-precision tradeoff) to the individual program statement. One promising research direction is to design parameterized versions of the focus operator which allow the user to fine-tune the focus operator not only to the individual program statements but also to the specific verification task. We carry this research direction one step further. We fine-tune the focus operator to each individual step of the analysis (for a specific verification task). This fine-tuning must be done automatically. Our idea is to use counterexampl...
