One nondeterministic module has affine ranking function -2 * x + 101 and consists of 7 locations. One nondeterministic module has affine ranking function y and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. 14.89/6.78 - StatisticsResult: Timing statistics 14.89/6.78 BüchiAutomizer plugin needed 1.5s and 3 iterations.
