One nondeterministic module has 2-nested ranking function (if -2 * x + 1 > 0 then 1 else 0), (if -2 * x + 1 > 0 then -2 * x + 1 else -2 * y + 2 * x + 1) and consists of 5 locations. The remainder module has 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.2s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 9.3s.
