One nondeterministic module has affine ranking function -1 * z + k and consists of 3 locations. One nondeterministic module has affine ranking function y and consists of 6 locations. One nondeterministic module has affine ranking function k + -1 * z and consists of 4 locations. One nondeterministic module has affine ranking function y and consists of 6 locations. One nondeterministic module has affine ranking function x + -1 * d and consists of 6 locations. One nondeterministic module has affine ranking function x + 1 and consists of 6 locations. One nondeterministic module has affine ranking function x + -1 * d and consists of 6 locations. One nondeterministic module has affine ranking function x + -1 * d and consists of 6 locations. One nondeterministic module has affine ranking function y and consists of 6 locations. One nondeterministic module has affine ranking function y and consists of 6 locations. 56.58/40.54 - StatisticsResult: Timing statistics 56.58/40.54 BüchiAutomizer plugin needed 34.2s and 11 iterations.
