### Pre-processing the ITS problem ###

Initial linear ITS problem
   Start location: __init
      0: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 ], cost: 1
      1: f145_0_main_EQ -> f145_0_main_EQ : arg1'=arg1P_2, arg2'=arg2P_2, [ arg2>arg1 && 1+arg1==arg1P_2 && arg2==arg2P_2 ], cost: 1
      2: f145_0_main_EQ -> f145_0_main_EQ : arg1'=arg1P_3, arg2'=arg2P_3, [ arg2<arg1 && arg1==arg1P_3 && 1+arg2==arg2P_3 ], cost: 1
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

Checking for constant complexity:
   The following rule is satisfiable with cost >= 1, yielding constant complexity:
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

Simplified all rules, resulting in:
   Start location: __init
      0: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 ], cost: 1
      1: f145_0_main_EQ -> f145_0_main_EQ : arg1'=1+arg1, [ arg2>arg1 ], cost: 1
      2: f145_0_main_EQ -> f145_0_main_EQ : arg2'=1+arg2, [ arg2<arg1 ], cost: 1
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

### Simplification by acceleration and chaining ###

Accelerating simple loops of location 1.
   Accelerating the following rules:
      1: f145_0_main_EQ -> f145_0_main_EQ : arg1'=1+arg1, [ arg2>arg1 ], cost: 1
      2: f145_0_main_EQ -> f145_0_main_EQ : arg2'=1+arg2, [ arg2<arg1 ], cost: 1

   Accelerated rule 1 with backward acceleration, yielding the new rule 4.
   Accelerated rule 2 with backward acceleration, yielding the new rule 5.
[accelerate] Nesting with 2 inner and 2 outer candidates
   Removing the simple loops: 1 2.

Accelerated all simple loops using metering functions (where possible):
   Start location: __init
      0: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 ], cost: 1
      4: f145_0_main_EQ -> f145_0_main_EQ : arg1'=arg2, [ arg2-arg1>=0 ], cost: arg2-arg1
      5: f145_0_main_EQ -> f145_0_main_EQ : arg2'=arg1, [ -arg2+arg1>=0 ], cost: -arg2+arg1
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

Chained accelerated rules (with incoming rules):
   Start location: __init
      0: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 ], cost: 1
      6: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg2P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 && -arg1P_1+arg2P_1>=0 ], cost: 1-arg1P_1+arg2P_1
      7: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg1P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 && arg1P_1-arg2P_1>=0 ], cost: 1+arg1P_1-arg2P_1
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

Removed unreachable locations (and leaf rules with constant cost):
   Start location: __init
      6: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg2P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 && -arg1P_1+arg2P_1>=0 ], cost: 1-arg1P_1+arg2P_1
      7: f1_0_main_Load -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg1P_1, [ arg2P_1>-1 && arg2>-1 && arg1P_1>-1 && arg1>0 && arg1P_1-arg2P_1>=0 ], cost: 1+arg1P_1-arg2P_1
      3: __init -> f1_0_main_Load : arg1'=arg1P_4, arg2'=arg2P_4, [], cost: 1

Eliminated locations (on tree-shaped paths):
   Start location: __init
      8: __init -> f145_0_main_EQ : arg1'=arg2P_1, arg2'=arg2P_1, [ arg2P_1>-1 && arg2P_4>-1 && arg1P_1>-1 && arg1P_4>0 && -arg1P_1+arg2P_1>=0 ], cost: 2-arg1P_1+arg2P_1
      9: __init -> f145_0_main_EQ : arg1'=arg1P_1, arg2'=arg1P_1, [ arg2P_1>-1 && arg2P_4>-1 && arg1P_1>-1 && arg1P_4>0 && arg1P_1-arg2P_1>=0 ], cost: 2+arg1P_1-arg2P_1
