Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * i) + 200001) and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 1.7s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 1.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 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 [1, 0, 0, 0, 0].
