One deterministic module has affine ranking function unknown-#length-unknown[a] + -2 * i and consists of 6 locations. One nondeterministic module has affine ranking function j and consists of 5 locations. 4 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.5s and 7 iterations.
