(1) Loat Proof (FINISHED)


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



Initial linear ITS problem

   Start location: f1

      0: f0 -> f2 : A'=free_1, C'=free, [ A>=B ], cost: 1

      1: f0 -> f0 : A'=free_3, D'=free_2, E'=0, [ B>=1+A ], cost: 1

      2: f0 -> f0 : A'=free_7, D'=free_4, E'=free_5, F'=free_6, [ 0>=1+free_5 && B>=1+A ], cost: 1

      3: f0 -> f0 : A'=free_11, D'=free_8, E'=free_9, F'=free_10, [ free_9>=1 && B>=1+A ], cost: 1

      4: f1 -> f0 : G'=free_12, [], cost: 1



Removed unreachable and leaf rules:

   Start location: f1

      1: f0 -> f0 : A'=free_3, D'=free_2, E'=0, [ B>=1+A ], cost: 1

      2: f0 -> f0 : A'=free_7, D'=free_4, E'=free_5, F'=free_6, [ 0>=1+free_5 && B>=1+A ], cost: 1

      3: f0 -> f0 : A'=free_11, D'=free_8, E'=free_9, F'=free_10, [ free_9>=1 && B>=1+A ], cost: 1

      4: f1 -> f0 : G'=free_12, [], cost: 1



### Simplification by acceleration and chaining ###



Accelerating simple loops of location 0.

   Accelerating the following rules:

      1: f0 -> f0 : A'=free_3, D'=free_2, E'=0, [ B>=1+A ], cost: 1

      2: f0 -> f0 : A'=free_7, D'=free_4, E'=free_5, F'=free_6, [ 0>=1+free_5 && B>=1+A ], cost: 1

      3: f0 -> f0 : A'=free_11, D'=free_8, E'=free_9, F'=free_10, [ free_9>=1 && B>=1+A ], cost: 1



   Accelerated rule 1 with NONTERM (after strengthening guard), yielding the new rule 5.

   Accelerated rule 2 with NONTERM (after strengthening guard), yielding the new rule 6.

   Accelerated rule 3 with NONTERM (after strengthening guard), yielding the new rule 7.

   Removing the simple loops:.



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

   Start location: f1

      1: f0 -> f0 : A'=free_3, D'=free_2, E'=0, [ B>=1+A ], cost: 1

      2: f0 -> f0 : A'=free_7, D'=free_4, E'=free_5, F'=free_6, [ 0>=1+free_5 && B>=1+A ], cost: 1

      3: f0 -> f0 : A'=free_11, D'=free_8, E'=free_9, F'=free_10, [ free_9>=1 && B>=1+A ], cost: 1

      5: f0 -> [3] : [ B>=1+A && B>=1+free_3 ], cost: INF

      6: f0 -> [3] : [ 0>=1+free_5 && B>=1+A && B>=1+free_7 ], cost: INF

      7: f0 -> [3] : [ free_9>=1 && B>=1+A && B>=1+free_11 ], cost: INF

      4: f1 -> f0 : G'=free_12, [], cost: 1



Chained accelerated rules (with incoming rules):

   Start location: f1

      4: f1 -> f0 : G'=free_12, [], cost: 1

      8: f1 -> f0 : A'=free_3, D'=free_2, E'=0, G'=free_12, [ B>=1+A ], cost: 2

      9: f1 -> f0 : A'=free_7, D'=free_4, E'=free_5, F'=free_6, G'=free_12, [ 0>=1+free_5 && B>=1+A ], cost: 2

     10: f1 -> f0 : A'=free_11, D'=free_8, E'=free_9, F'=free_10, G'=free_12, [ free_9>=1 && B>=1+A ], cost: 2

     11: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF

     12: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF

     13: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF



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

   Start location: f1

     11: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF

     12: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF

     13: f1 -> [3] : G'=free_12, [ B>=1+A ], cost: INF
