We present the new version of the Loop Acceleration Tool (LoAT), a powerfultool for proving non-termination and worst-case lower bounds for programsoperating on integers. It is based on a novel calculus for loop acceleration,i.e., transforming loops into non-deterministic straight-line code, and forfinding non-terminating configurations. To implement it efficiently, LoAT usesa new approach based on SMT solving and unsat cores. An extensive evaluationshows that LoAT is highly competitive with other state-of-the-art tools forproving non-termination. While no other tool is able to deduce worst-case lowerbounds for full integer programs, we also demonstrate that LoAT significantlyoutperforms its predecessors.
