    Your program was decomposed into 5 terminating modules (5 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.5 modules have a trivial ranking function, the largest among these consists of 8 locations. The remainder module has 603 locations.
  - StatisticsResult: Timing statistics
    BüchiAutomizer plugin needed 2.7s and 6 iterations.  TraceHistogramMax:1. Analysis of lassos took 2.0s. Construction of modules took 0.3s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 0. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 5 MinimizatonAttempts, 173 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1.	Nontrivial modules had stage [0, 0, 0, 0, 0].
