One deterministic module has affine ranking function -1 * array + -4 * i + unknown-#length-unknown[\result] and consists of 5 locations. One deterministic module has affine ranking function ldv_global_msg_list + -4 * i + 1 and consists of 13 locations. One deterministic module has affine ranking function len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[array] + -1 * array + -4 * i and consists of 3 locations. One deterministic module has affine ranking function 2 * j + 1 and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.9s and 13 iterations.
