(1) Loat Proof (FINISHED)


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



Initial linear ITS problem

   Start location: f300

      0: f2 -> f2 : B'=C, D'=free_2, E'=free, F'=free_1, [ A>=1 ], cost: 1

      1: f300 -> f1 : B'=free_9, C'=free_4, D'=free_6, E'=free_8, H'=free_9, Q'=free_3, J'=free_5, K'=free_7, [ 0>=G ], cost: 1

      2: f300 -> f2 : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: 1

      3: f300 -> f1 : B'=free_24, C'=free_24, D'=free_19, E'=free_21, F'=free_23, H'=free_18, Q'=free_20, J'=free_22, K'=free_17, [ 0>=A && G>=1 ], cost: 1



Checking for constant complexity:

   The following rule is satisfiable with cost >= 1, yielding constant complexity:

      1: f300 -> f1 : B'=free_9, C'=free_4, D'=free_6, E'=free_8, H'=free_9, Q'=free_3, J'=free_5, K'=free_7, [ 0>=G ], cost: 1



Removed unreachable and leaf rules:

   Start location: f300

      0: f2 -> f2 : B'=C, D'=free_2, E'=free, F'=free_1, [ A>=1 ], cost: 1

      2: f300 -> f2 : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: 1



### Simplification by acceleration and chaining ###



Accelerating simple loops of location 0.

   Accelerating the following rules:

      0: f2 -> f2 : B'=C, D'=free_2, E'=free, F'=free_1, [ A>=1 ], cost: 1



   Accelerated rule 0 with NONTERM, yielding the new rule 4.

   Removing the simple loops: 0.



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

   Start location: f300

      4: f2 -> [3] : [ A>=1 ], cost: NONTERM

      2: f300 -> f2 : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: 1



Chained accelerated rules (with incoming rules):

   Start location: f300

      2: f300 -> f2 : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: 1

      5: f300 -> [3] : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: NONTERM



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

   Start location: f300

      5: f300 -> [3] : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: NONTERM



### Computing asymptotic complexity ###



Fully simplified ITS problem

   Start location: f300

      5: f300 -> [3] : B'=free_16, C'=free_16, D'=free_11, E'=free_13, F'=free_15, H'=free_10, Q'=free_12, J'=free_14, [ A>=1 && G>=1 ], cost: NONTERM



Computing asymptotic complexity for rule 5

   Guard is satisfiable, yielding nontermination

   Resulting cost NONTERM 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: NONTERM

   Rule cost:   NONTERM

   Rule guard:  [ A>=1 && G>=1 ]



NO
