One nondeterministic module has affine ranking function \old(b) and consists of 4 locations. One nondeterministic module has affine ranking function \old(c) and consists of 5 locations. 4 modules have a trivial ranking function, the largest among these consists of 7 locations. 20.53/11.61 - StatisticsResult: Timing statistics 20.53/11.61 BüchiAutomizer plugin needed 5.6s and 7 iterations.
