- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 4 terminating modules (4 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.4 modules have a trivial ranking function, the largest among these consists of 5 locations. The remainder module has 468 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 3.0s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 2.0s. Construction of modules took 0.2s. Büchi inclusion checks took 0.5s.
