One deterministic module has affine ranking function -1 * i + hi and consists of 3 locations. One deterministic module has affine ranking function -1 * i + hi and consists of 3 locations. One deterministic module has affine ranking function -1 * i + k4 and consists of 5 locations. One deterministic module has affine ranking function -1 * i + k4 and consists of 4 locations. One deterministic module has affine ranking function -1 * i + hi and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.4s and 6 iterations.
