One deterministic module has affine ranking function array_size + -1 * i and consists of 3 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[p][p] and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[p][p] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 5 iterations.
