One deterministic module has affine ranking function 2 * \old(v) + 1 and consists of 5 locations. One deterministic module has affine ranking function 2 * \old(unknown-#memory_int-unknown)[p][p] + 1 and consists of 5 locations. One nondeterministic module has affine ranking function 2 * \old(unknown-#memory_int-unknown)[p][0] + 1 and consists of 7 locations. 3 modules have a trivial ranking function, the largest among these consists of 29 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 41.9s and 7 iterations.
