One nondeterministic module has affine ranking function unknown-#memory_int-unknown[a][a + i * 4] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.7s and 8 iterations.
