One deterministic module has affine ranking function unknown-#memory_int-unknown[y_ref][y_ref] and consists of 6 locations. One deterministic module has affine ranking function (if aux-(*x_ref > 0) && (*y_ref > 0)-aux then 1 else 0) and consists of 5 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x_ref][x_ref] and consists of 4 locations. One deterministic module has affine ranking function org.eclipse.cdt.internal.core.dom.parser.c.CASTIdExpression@155c49d0 and consists of 3 locations. 6 modules have a trivial ranking function, the largest among these consists of 12 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.1s and 11 iterations.
