- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 2 deterministic, 1 nondeterministic). One deterministic module has affine ranking function unknown-#memory_int-unknown[qq][qq] and consists of 8 locations. One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[op][op] + 1 and consists of 5 locations. One nondeterministic module has affine ranking function 2 * unknown-#memory_int-unknown[op][0] + 1 and consists of 7 locations. 2 modules have a trivial ranking function, the largest among these consists of 19 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 24.0s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 20.4s. Construction of modules took 0.3s. Büchi inclusion checks took 3.0s.
