One deterministic module has affine ranking function array_size + -1 * k and consists of 5 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[a] and consists of 5 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[numbers][k * 4 + -4 + numbers] and consists of 8 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[numbers][-4 + k * 4 + numbers] and consists of 8 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. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.9s and 11 iterations.
