One deterministic module has affine ranking function unknown-#length-unknown[v] + -4 * j + -1 * v and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[v] + -2 * j and consists of 7 locations. One deterministic module has affine ranking function 2 * i + 1 and consists of 5 locations. One deterministic module has affine ranking function -1 * v + unknown-#length-unknown[v] + -4 * k and consists of 3 locations. One nondeterministic module has affine ranking function 16 * i + unknown-#length-unknown[v] and consists of 5 locations. 7 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 25.1s and 13 iterations.
