* Witness Printer took 5.87ms. Allocated memory is still 117.4MB. Free memory was 78.8MB in the beginning and 78.8MB in the end (delta: 21.0kB). There was no memory consumed. Max. memory is 16.1GB.
* Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction:
- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 1 terminating modules (0 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has affine ranking function (((long long) -2 * i) + 9) and consists of 5 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 1.4s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 1.1s. 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 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].
