One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y_ref][y_ref] 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 5.8s and 4 iterations.
