One deterministic module has affine ranking function -1 * a + unknown-#length-unknown[a] + -4 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[a][i * 4 + a] and consists of 4 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[a][i * 4 + a] and consists of 4 locations. One nondeterministic module has affine ranking function -1 * unknown-#memory_int-unknown[a][a + i * 4] and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[a][a + i * 4] 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 8.9s and 7 iterations.
