Ultimate Automizer with Array Interpolation - (Competition Contribution)

Ultimate Automizer is a software verification tool that is able to analyze reachability of an error label, memory safety, and termination of C programs. For all three tasks, our tool follows an automata-based approach where interpolation is used to compute proofs for traces. The interpolants are generated via a new scheme that requires only the post operator, unsatisfiable cores and live variable analysis. This new scheme enables our tool to use the SMT theory of arrays in combination with interpolation.
