One deterministic module has affine ranking function -1 * x and consists of 4 locations. One deterministic module has affine ranking function org.eclipse.cdt.internal.core.dom.parser.c.CASTBinaryExpression@25c16bf and consists of 6 locations. One deterministic module has 2-phase ranking function (if x > 0 then 1 else 0), (if x > 0 then x else -1 * x) and consists of 6 locations. One deterministic module has affine ranking function -1 * x and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.7s and 6 iterations.
