(1) Loat Proof (FINISHED)


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



Initial linear ITS problem

   Start location: f1

      0: f0 -> f2 : B'=free, [ 0>=A ], cost: 1

      1: f0 -> f0 : A'=C+A, C'=-1+C, [ A>=1 ], cost: 1

      2: f1 -> f0 : [], cost: 1



Removed unreachable and leaf rules:

   Start location: f1

      1: f0 -> f0 : A'=C+A, C'=-1+C, [ A>=1 ], cost: 1

      2: f1 -> f0 : [], cost: 1



### Simplification by acceleration and chaining ###



Accelerating simple loops of location 0.

   Accelerating the following rules:

      1: f0 -> f0 : A'=C+A, C'=-1+C, [ A>=1 ], cost: 1



   Found no metering function for rule 1.

   Removing the simple loops:.



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

   Start location: f1

      1: f0 -> f0 : A'=C+A, C'=-1+C, [ A>=1 ], cost: 1

      2: f1 -> f0 : [], cost: 1



Chained accelerated rules (with incoming rules):

   Start location: f1

      2: f1 -> f0 : [], cost: 1

      3: f1 -> f0 : A'=C+A, C'=-1+C, [ A>=1 ], cost: 2



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

   Start location: f1



### Computing asymptotic complexity ###



Fully simplified ITS problem

   Start location: f1



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

   Complexity:  Unknown

   Cpx degree:  ?

   Solved cost: 0

   Rule cost:   0

   Rule guard:  []
