Removing the self-loops: 0. Removed all Self-loops using metering functions (where possible): Start location: f300 4: f2 -> [3] : [ A>=1 ], cost: INF 2: f300 -> f2 : B'=free_11, C'=free_11, D'=free_16, E'=free_10, F'=free_12, H'=free_13, Q'=free_15, J'=free_14, [ A>=1 && G>=1 ], cost: 1 Applied simple chaining: Start location: f300 2: f300 -> [3] : B'=free_11, C'=free_11, D'=free_16, E'=free_10, F'=free_12, H'=free_13, Q'=free_15, J'=free_14, [ A>=1 && G>=1 && A>=1 ], cost: INF Final control flow graph problem, now checking costs for infinitely many models: Start location: f300 2: f300 -> [3] : B'=free_11, C'=free_11, D'=free_16, E'=free_10, F'=free_12, H'=free_13, Q'=free_15, J'=free_14, [ A>=1 && G>=1 && A>=1 ], cost: INF Computing complexity for remaining 1 transitions. Found new complexity INF, because: INF sat. The final runtime is determined by this resulting transition: Final Guard: A>=1 && G>=1 && A>=1 Final Cost: INF Obtained the following complexity w.r.t. the length of the input n: Complexity class: INF Complexity value: INF WORST_CASE(INF,?)
