One deterministic module has affine ranking function unknown-#memory_int-unknown[M][M] + -1 * unknown-#memory_int-unknown[i][i] and consists of 6 locations. One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[j][j] + unknown-#memory_int-unknown[N][N] and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 24.7s and 3 iterations.
