- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function unknown-#length-unknown[s] + 2 * s and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 4.9s and 3 iterations. TraceHistogramMax:2. Analysis of lassos took 4.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 1 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 [1, 0, 0, 0, 0].
