One deterministic module has affine ranking function -1 * i + l1 and consists of 3 locations. One deterministic module has affine ranking function l2 + -1 * j and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[B] + -4 * j + -1 * A 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 10.2s and 8 iterations.
