One deterministic module has affine ranking function -1 * v + unknown-#length-unknown[v] + -4 * j and consists of 5 locations. One deterministic module has affine ranking function -1 * v + unknown-#length-unknown[v] + -4 * j and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[v] + 16 * i and consists of 5 locations.

One deterministic module has affine ranking function -1 * v + unknown-#length-unknown[v] + -4 * k and consists of 3 locations. One nondeterministic module has affine ranking function j + 4 * i and consists of 8 locations. One nondeterministic module has affine ranking function i and consists of 5 locations. 8 modules have a trivial ranking function, the largest among these consists of 26 locations. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer: - ExceptionOrErrorResult: ClassCastException: class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator cannot be cast to class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData (de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator and de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @560348e6) de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer: ClassCastException: class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator cannot be cast to class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData (de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator and de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @560348e6): de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer.BuchiCegarLoopBenchmark.prettyprintBenchmarkData(BuchiCegarLoopBenchmark.java:178) RESULT: Ultimate could not prove your program: Toolchain returned no result.
