One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[y][y] + 100 and consists of 14 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[z][z] + 100 and consists of 13 locations. 12 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.4s and 15 iterations.
