(1) Loat Proof (FINISHED)


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



Initial linear ITS problem

   Start location: f2

      0: f1 -> f1 : C'=free, D'=free_1, E'=free_2, [ A>=1+B ], cost: 1

      1: f1 -> f300 : C'=free_3, D'=free_4, F'=free_5, [ B>=A ], cost: 1

      2: f2 -> f1 : G'=free_6, H'=free_7, [], cost: 1



Removed unreachable and leaf rules:

   Start location: f2

      0: f1 -> f1 : C'=free, D'=free_1, E'=free_2, [ A>=1+B ], cost: 1

      2: f2 -> f1 : G'=free_6, H'=free_7, [], cost: 1



### Simplification by acceleration and chaining ###



Accelerating simple loops of location 0.

   Accelerating the following rules:

      0: f1 -> f1 : C'=free, D'=free_1, E'=free_2, [ A>=1+B ], cost: 1



   Accelerated rule 0 with NONTERM, yielding the new rule 3.

   Removing the simple loops: 0.



Accelerated all simple loops using metering functions (where possible):

   Start location: f2

      3: f1 -> [3] : [ A>=1+B ], cost: INF

      2: f2 -> f1 : G'=free_6, H'=free_7, [], cost: 1



Chained accelerated rules (with incoming rules):

   Start location: f2

      2: f2 -> f1 : G'=free_6, H'=free_7, [], cost: 1

      4: f2 -> [3] : G'=free_6, H'=free_7, [ A>=1+B ], cost: INF



Removed unreachable locations (and leaf rules with constant cost):

   Start location: f2

      4: f2 -> [3] : G'=free_6, H'=free_7, [ A>=1+B ], cost: INF



### Computing asymptotic complexity ###



Fully simplified ITS problem

   Start location: f2

      4: f2 -> [3] : G'=free_6, H'=free_7, [ A>=1+B ], cost: INF



Computing asymptotic complexity for rule 4

   Resulting cost INF has complexity: Nonterm



Found new complexity Nonterm.



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

   Complexity:  Nonterm

   Cpx degree:  Nonterm

   Solved cost: INF

   Rule cost:   INF

   Rule guard:  [ A>=1+B ]



NO
