- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 7 terminating modules (3 trivial, 3 deterministic, 1 nondeterministic). One deterministic module has affine ranking function ((long) -1 * x) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function x and consists of 5 locations. One nondeterministic module has affine ranking function x and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 2.7s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 1.8s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 5. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 14 StatesRemovedByMinimization, 5 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 [3, 0, 1, 0, 0].
