One nondeterministic module has affine ranking function -1 * i and consists of 5 locations. One nondeterministic module has affine ranking function n + -1 * i and consists of 4 locations. One nondeterministic module has affine ranking function -2 * j + 2 * i + 1 and consists of 2 locations. 15.46/7.64 - StatisticsResult: Timing statistics 15.46/7.64 BüchiAutomizer plugin needed 2.2s and 4 iterations.
