One deterministic module has affine ranking function -2 * unknown-#memory_int-unknown[j_ref][j_ref] + -2 * unknown-#memory_int-unknown[i_ref][i_ref] + 2 * k + 201 and consists of 8 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.4s and 3 iterations.
