- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 4 terminating modules (4 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.4 modules have a trivial ranking function, the largest among these consists of 6 locations. The remainder module has 523 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 6.3s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 5.3s. Construction of modules took 0.3s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 0. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 4 MinimizatonAttempts, 1232 StatesRemovedByMinimization, 2 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].
