One deterministic module has affine ranking function -2 * unknown-#memory_int-unknown[z][z] + 199 and consists of 5 locations. One deterministic module has affine ranking function 199 + -2 * unknown-#memory_int-unknown[y][y] and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.6s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 8.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
