One nondeterministic module has affine ranking function n + -1 * i and consists of 4 locations. One nondeterministic module has affine ranking function -1 * j + m and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.9s and 3 iterations.
