   Start location: __init
      0: f1 -> f2 : arg1'=arg1P_1, arg2'=arg2P_1, arg3'=arg3P_1, [ arg1==arg1P_1 && arg2==arg2P_1 ], cost: 1
      1: f2 -> f3 : arg1'=arg1P_2, arg2'=arg2P_2, arg3'=arg3P_2, [ 0==arg1P_2 && arg2==arg2P_2 && arg3==arg3P_2 ], cost: 1
      2: f3 -> f4 : arg1'=arg1P_3, arg2'=arg2P_3, arg3'=arg3P_3, [ arg1==arg1P_3 && 0==arg2P_3 && arg3==arg3P_3 ], cost: 1

      8: __init -> f1 : arg1'=arg1P_9, arg2'=arg2P_9, arg3'=arg3P_9, [], cost: 1

Checking for constant complexity:
   The following rule is satisfiable with cost >= 1, yielding constant complexity:
      8: __init -> f1 : arg1'=arg1P_9, arg2'=arg2P_9, arg3'=arg3P_9, [], cost: 1

Removed unreachable and leaf rules:
   Start location: __init

      8: __init -> f1 : arg1'=arg1P_9, arg2'=arg2P_9, arg3'=arg3P_9, [], cost: 1

Simplified all rules, resulting in:
   Start location: __init
      0: f1 -> f2 : arg3'=arg3P_1, [], cost: 1
      1: f2 -> f3 : arg1'=0, [], cost: 1

Eliminated locations (on linear paths):
   Start location: __init
     14: f4 -> f4 : arg1'=1+arg1, arg2'=arg2+arg1, [ arg1<arg3 ], cost: 4
     11: __init -> f4 : arg1'=0, arg2'=0, arg3'=arg3P_1, [], cost: 4

Accelerating simple loops of location 3.
   Accelerating the following rules:
     14: f4 -> f4 : arg1'=1+arg1, arg2'=arg2+arg1, [ arg1<arg3 ], cost: 4

   Accelerated rule 14 with backward acceleration, yielding the new rule 15.
[accelerate] Nesting with 1 inner and 1 outer candidates
   Removing the simple loops: 14.

Accelerated all simple loops using metering functions (where possible):
   Start location: __init
     15: f4 -> f4 : arg1'=arg3, arg2'=arg2+(arg3-arg1)*arg1-1/2*arg3+1/2*(arg3-arg1)^2+1/2*arg1, [ arg3-arg1>=0 ], cost: 4*arg3-4*arg1
     11: __init -> f4 : arg1'=0, arg2'=0, arg3'=arg3P_1, [], cost: 4

Chained accelerated rules (with incoming rules):
   Start location: __init
     11: __init -> f4 : arg1'=0, arg2'=0, arg3'=arg3P_1, [], cost: 4
     16: __init -> f4 : arg1'=arg3P_1, arg2'=-1/2*arg3P_1+1/2*arg3P_1^2, arg3'=arg3P_1, [ arg3P_1>=0 ], cost: 4+4*arg3P_1

Removed unreachable locations (and leaf rules with constant cost):
   Start location: __init
     16: __init -> f4 : arg1'=arg3P_1, arg2'=-1/2*arg3P_1+1/2*arg3P_1^2, arg3'=arg3P_1, [ arg3P_1>=0 ], cost: 4+4*arg3P_1

Computing asymptotic complexity for rule 16
   Resulting cost 0 has complexity: Unknown

Obtained the following overall complexity (w.r.t. the length of the input n):
