Initial Control flow graph problem:
  Start location: start
      0: eval1 -> eval2 : B'=0, [ A>=1 ], cost: 1
      2: eval2 -> eval1 : A'=-1+A, [ A>=1 && B>=0 && B>=A ], cost: 1
      1: eval2 -> eval2 : B'=1+B, [ A>=1 && B>=0 && A>=1+B ], cost: 1
      3: start -> eval1 : [], cost: 1

Eliminating 1 self-loops for location eval2
  Self-Loop 1 has the metering function: -B+A, resulting in the new transition 4.
  Removing the self-loops: 1.

Removed all Self-loops using metering functions (where possible):
  Start location: start
      0: eval1 -> eval2 : B'=0, [ A>=1 ], cost: 1
      4: eval2 -> [3] : B'=A, [ A>=1 && B>=0 && A>=1+B ], cost: -B+A
      3: start -> eval1 : [], cost: 1
      2: [3] -> eval1 : A'=-1+A, [ A>=1 && B>=0 && B>=A ], cost: 1


Applied simple chaining:
  Start location: start
      0: eval1 -> eval1 : A'=-1+A, B'=A, [ A>=1 && A>=1 && 0>=0 && A>=1 && A>=1 && A>=0 && A>=A ], cost: 2+A
      3: start -> eval1 : [], cost: 1

Eliminating 1 self-loops for location eval1
  Self-Loop 0 has the metering function: A, resulting in the new transition 5.
  Removing the self-loops: 0.

Removed all Self-loops using metering functions (where possible):
  Start location: start
      5: eval1 -> [4] : A'=0, B'=1, [ A>=1 ], cost: 1/2*A^2+5/2*A
      3: start -> eval1 : [], cost: 1


Applied simple chaining:
  Start location: start
      3: start -> [4] : A'=0, B'=1, [ A>=1 ], cost: 1+1/2*A^2+5/2*A


Final control flow graph problem, now checking costs for infinitely many models:
  Start location: start
      3: start -> [4] : A'=0, B'=1, [ A>=1 ], cost: 1+1/2*A^2+5/2*A


Computing complexity for remaining 1 transitions.

  Found configuration with infinitely models for cost: 1+1/2*A^2+5/2*A
  and guard: A>=1:
  A: Pos

Found new complexity n^2, because: Found infinity configuration.


The final runtime is determined by this resulting transition:
  Final Guard: A>=1
  Final Cost:  1+1/2*A^2+5/2*A

Obtained the following complexity w.r.t. the length of the input n:
  Complexity class: n^2
  Complexity value: 2
