One deterministic module has affine ranking function N + -1 * cnt and consists of 7 locations. One deterministic module has affine ranking function -2 * cnt + 3 * N + -2 * delta and consists of 7 locations. One deterministic module has affine ranking function -2 * cnt + 3 * N + -2 * delta and consists of 7 locations. One deterministic module has 2-lex ranking function -3 * cnt + 5 * N, N + 3 * x and consists of 7 locations. One deterministic module has 2-lex ranking function -3 * cnt + 5 * N, x * 3 + N and consists of 7 locations. One deterministic module has affine ranking function -2 * delta + -2 * cnt + 3 * N and consists of 7 locations. One deterministic module has affine ranking function N + -1 * cnt and consists of 14 locations. One nondeterministic module has 2-lex ranking function -3 * cnt + 5 * N, N + 3 * x and consists of 7 locations. One nondeterministic module has affine ranking function -2 * cnt + 3 * N + -2 * delta and consists of 7 locations. 2 modules have a trivial ranking function, the largest among these consists of 28 locations. - TerminationAnalysisResult: Termination proven Buchi Automizer proved that your program is terminating RESULT: Ultimate proved your program to be correct!
