One nondeterministic module has affine ranking function y + -1 * x and consists of 3 locations. One nondeterministic module has affine ranking function y + -1 * x and consists of 3 locations. One nondeterministic module has affine ranking function -1 * y + x and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. 15.93/7.72 - StatisticsResult: Timing statistics 15.93/7.72 BüchiAutomizer plugin needed 2.4s and 4 iterations.
