- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 1 terminating modules (0 trivial, 1 deterministic, 0 nondeterministic). One deterministic module has 2-nested ranking function (if -1 * x + z > 0 then 1 else 0), (if -1 * x + z > 0 then -1 * x + z else y + -1 * x) and consists of 4 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 0.9s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 0.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. 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].
