One deterministic module has affine ranking function n + -1 * i1 and consists of 4 locations. One deterministic module has affine ranking function -1 * i2 + n and consists of 3 locations. One deterministic module has affine ranking function -1 * i2 + n and consists of 3 locations. One deterministic module has affine ranking function -1 * i2 + n and consists of 3 locations. - TerminationAnalysisResult: Termination proven Buchi Automizer proved that your program is terminating RESULT: Ultimate proved your program to be correct!
