Trying to load file: main.koat Initial Control flow graph problem: Start location: f0 0: f0 -> f1 : [], cost: 1 1: f1 -> f1 : A'=B+A, B'=B-C, C'=1+C, [ A>=1 ], cost: 1 Eliminating 1 self-loops for location f1 Removing the self-loops: 1. Adding an epsilon transition (to model nonexecution of the loops): 3. Removed all Self-loops using metering functions (where possible): Start location: f0 0: f0 -> f1 : [], cost: 1 2: f1 -> [2] : A'=B+A, B'=B-C, C'=1+C, [ A>=1 ], cost: 1 3: f1 -> [2] : [], cost: 0 Applied chaining over branches and pruning: Start location: f0 Final control flow graph problem, now checking costs for infinitely many models: Start location: f0 Computing complexity for remaining 0 transitions. The final runtime is determined by this resulting transition: Final Guard: Final Cost: 1 Obtained the following complexity w.r.t. the length of the input n: Complexity class: const Complexity value: 0 WORST_CASE(Omega(1),?)
