- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 1 terminating modules (1 trivial, 0 deterministic, 0 nondeterministic) and one nonterminating remainder module.1 modules have a trivial ranking function, the largest among these consists of 6 locations. The remainder module has 118 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 5.4s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 5.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s.
