One deterministic module has affine ranking function l1 + -1 * i and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[B] + -4 * j and consists of 5 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (Blen * sizeof(int))] + -2 * j and consists of 7 locations. One nondeterministic module has affine ranking function 3 * unknown-#length-unknown[__builtin_alloca (Blen * sizeof(int))] + -4 * j and consists of 10 locations. One nondeterministic module has affine ranking function -2 * j + unknown-#length-unknown[__builtin_alloca (Alen * sizeof(int))] and consists of 14 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[B] + -4 * j and consists of 5 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 36.4s and 11 iterations.
