One deterministic module has affine ranking function -4 * k + unknown-#length-unknown[numbers] and consists of 5 locations. One deterministic module has affine ranking function -4 * i + -1 * a + unknown-#length-unknown[a] and consists of 3 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[numbers][numbers + k * 4 + -4] and consists of 8 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[numbers][numbers] and consists of 6 locations. One deterministic module has affine ranking function 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][i * 4 + a] and consists of 4 locations. 5 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.8s and 12 iterations.
