One deterministic module has affine ranking function unknown-size-unknown + -1 * aux-#t~loopctr8-aux and consists of 3 locations. One deterministic module has affine ranking function -1 * aux-#t~loopctr10-aux + unknown-size-unknown and consists of 2 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.4s and 3 iterations.
