One deterministic module has affine ranking function -2 * x1 + 2 * n1 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * x1 + 2 * n1 + 1 and consists of 4 locations. One deterministic module has affine ranking function 2 * n2 + -2 * x2 + t and consists of 5 locations. One deterministic module has affine ranking function 2 * n2 + -2 * x2 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * x3 + 2 * n3 + 1 and consists of 4 locations. One deterministic module has affine ranking function -1 * t + -2 * x3 + 2 * n3 and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. - TerminationAnalysisResult: Termination proven Buchi Automizer proved that your program is terminating RESULT: Ultimate proved your program to be correct!
