One nondeterministic module has affine ranking function -1 * \old(m) and consists of 5 locations. One nondeterministic module has affine ranking function m and consists of 8 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.4s and 4 iterations.
