One nondeterministic module has affine ranking function i and consists of 3 locations. One nondeterministic module has affine ranking function -1 * i + y and consists of 2 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. 14.74/6.82 - StatisticsResult: Timing statistics 14.74/6.82 BüchiAutomizer plugin needed 1.4s and 3 iterations.
