One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[s2] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.9s and 6 iterations.
