Trying to load file: main.koat Initial Control flow graph problem: Start location: f3 0: f3 -> f2 : [], cost: 1 1: f2 -> f2 : A'=-1+A, [ A>=1 ], cost: 1 2: f2 -> f300 : A'=-1+A, B'=free, [ 0>=A ], cost: 1 Simplified the transitions: Start location: f3 0: f3 -> f2 : [], cost: 1 1: f2 -> f2 : A'=-1+A, [ A>=1 ], cost: 1 Eliminating 1 self-loops for location f2 Self-Loop 1 has the metering function: A, resulting in the new transition 3. Removing the self-loops: 1. Removed all Self-loops using metering functions (where possible): Start location: f3 0: f3 -> f2 : [], cost: 1 3: f2 -> [3] : A'=0, [ A>=1 ], cost: A Applied simple chaining: Start location: f3 0: f3 -> [3] : A'=0, [ A>=1 ], cost: 1+A Final control flow graph problem, now checking costs for infinitely many models: Start location: f3 0: f3 -> [3] : A'=0, [ A>=1 ], cost: 1+A Computing complexity for remaining 1 transitions. Found configuration with infinitely models for cost: 1+A and guard: A>=1: A: Pos Found new complexity n^1, because: Found infinity configuration. The final runtime is determined by this resulting transition: Final Guard: A>=1 Final Cost: 1+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),?)
