* Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction:
- 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 -2 * splverifierCounter + 7 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 2.5s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization No data available. 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].
