FOCI: and interpolating prover. FOCI is a decision procedure for quantifier-free first-order formulas. It supports certain interpreted theories, such as equality, uninterpreted functions, linear arithmetic, and arrays. Most importantly, it can compute quantifier-free Craig interpolants for inconsistent pairs (or more generally, sequences) of formulas. This has a number of applications in infinite-state verification, for example, discovering predicates in predicate abstraction, and computing inductive invariants.
