Trying to load file: main.koat Initial Control flow graph problem: Start location: start 0: eval -> eval : A'=-1+A, C'=-1+C, [ A>=0 && B^3>=C ], cost: 1 1: eval -> eval : B'=B+C, C'=-1+C, [ A>=0 && B^3>=C ], cost: 1 2: start -> eval : [], cost: 1 Eliminating 2 self-loops for location eval Self-Loop 0 has the metering function: 1+A, resulting in the new transition 3. Removing the self-loops: 0 1. Adding an epsilon transition (to model nonexecution of the loops): 5. Removed all Self-loops using metering functions (where possible): Start location: start 3: eval -> [2] : A'=-1, C'=-1+C-A, [ A>=0 && B^3>=C ], cost: 1+A 4: eval -> [2] : B'=B+C, C'=-1+C, [ A>=0 && B^3>=C ], cost: 1 5: eval -> [2] : [], cost: 0 2: start -> eval : [], cost: 1 Applied chaining over branches and pruning: Start location: start 6: start -> [2] : A'=-1, C'=-1+C-A, [ A>=0 && B^3>=C ], cost: 2+A Final control flow graph problem, now checking costs for infinitely many models: Start location: start 6: start -> [2] : A'=-1, C'=-1+C-A, [ A>=0 && B^3>=C ], cost: 2+A Computing complexity for remaining 1 transitions. Found configuration with infinitely models for cost: 2+A and guard: A>=0 && B^3>=C: B: Pos, C: Both, A: Pos Found new complexity n^1, because: Found infinity configuration. The final runtime is determined by this resulting transition: Final Guard: A>=0 && B^3>=C Final Cost: 2+A Obtained the following complexity w.r.t. the length of the input n: Complexity class: n^1 Complexity value: 1 WORST_CASE(Omega(n^1),?)
