One nondeterministic module has affine ranking function 2 * x + 1 and consists of 4 locations. One nondeterministic module has affine ranking function -1 * y + x and consists of 5 locations. 15.66/7.16 - StatisticsResult: Timing statistics 15.66/7.16 BüchiAutomizer plugin needed 1.8s and 3 iterations.
