One deterministic module has affine ranking function (19999 + ((long long) -2 * x1)) and consists of 6 locations. One deterministic module has affine ranking function (19999 + ((long long) -2 * x2)) and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 6 locations. - TerminationAnalysisResult: Termination proven Buchi Automizer proved that your program is terminating RESULT: Ultimate proved your program to be correct!
