One deterministic module has affine ranking function i and consists of 4 locations. One deterministic module has affine ranking function i and consists of 3 locations. One deterministic module has affine ranking function (i + ((long) -1 * m)) and consists of 4 locations. One nondeterministic module has affine ranking function i and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.8s and 5 iterations.
