- StatisticsResult: Constructed decomposition of program
Your program was decomposed into 5 terminating modules (2 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * i + length3 and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * s and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations.
- StatisticsResult: Timing statistics
BüchiAutomizer plugin needed 8.3s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 7.5s. Construction of modules took 0.1s. Büchi inclusion checks took 0.5s.
