Trying to load file: main.koat Initial Control flow graph problem: Start location: f0 0: f0 -> f1 : [ A>=1 && 0>=1+B ], cost: 1 1: f1 -> f1 : A'=-B+A, [ A>=1+B && 0>=1+B ], cost: 1 Eliminating 1 self-loops for location f1 Self-Loop 1 has unbounded runtime, resulting in the new transition 2. Removing the self-loops: 1. Removed all Self-loops using metering functions (where possible): Start location: f0 0: f0 -> f1 : [ A>=1 && 0>=1+B ], cost: 1 2: f1 -> [2] : [ A>=1+B && 0>=1+B ], cost: INF Applied simple chaining: Start location: f0 0: f0 -> [2] : [ A>=1 && 0>=1+B && A>=1+B && 0>=1+B ], cost: INF Final control flow graph problem, now checking costs for infinitely many models: Start location: f0 0: f0 -> [2] : [ A>=1 && 0>=1+B && A>=1+B && 0>=1+B ], 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 && 0>=1+B && A>=1+B && 0>=1+B 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,?)
