Trying to load file: main.koat Initial Control flow graph problem: Start location: f3 0: f2 -> f2 : B'=-1+B, [ 29>=A ], cost: 1 1: f2 -> f300 : B'=-1+B, [ A>=30 ], cost: 1 2: f300 -> f2 : [ 19>=B ], cost: 1 3: f300 -> f1 : C'=free, [ B>=20 ], cost: 1 4: f3 -> f300 : [], cost: 1 Simplified the transitions: Start location: f3 0: f2 -> f2 : B'=-1+B, [ 29>=A ], cost: 1 1: f2 -> f300 : B'=-1+B, [ A>=30 ], cost: 1 2: f300 -> f2 : [ 19>=B ], cost: 1 4: f3 -> f300 : [], cost: 1 Eliminating 1 self-loops for location f2 Self-Loop 0 has unbounded runtime, resulting in the new transition 5. Removing the self-loops: 0. Removed all Self-loops using metering functions (where possible): Start location: f3 5: f2 -> [4] : [ 29>=A ], cost: INF 2: f300 -> f2 : [ 19>=B ], cost: 1 4: f3 -> f300 : [], cost: 1 1: [4] -> f300 : B'=-1+B, [ A>=30 ], cost: 1 Applied simple chaining: Start location: f3 2: f300 -> [4] : [ 19>=B && 29>=A ], cost: INF 4: f3 -> f300 : [], cost: 1 1: [4] -> f300 : B'=-1+B, [ A>=30 ], cost: 1 Applied chaining over branches and pruning: Start location: f3 6: f300 -> [5] : [ 19>=B && 29>=A ], cost: INF 4: f3 -> f300 : [], cost: 1 Applied simple chaining: Start location: f3 4: f3 -> [5] : [ 19>=B && 29>=A ], cost: INF Final control flow graph problem, now checking costs for infinitely many models: Start location: f3 4: f3 -> [5] : [ 19>=B && 29>=A ], 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: 19>=B && 29>=A 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,?)
