For Pair COND_676_0_APPE_FIELDACCESS(TRUE, x0) → 676_0_APPE_FIELDACCESS(+(x0, -1)) the following chains were created:

• We consider the chain COND_676_0_APPE_FIELDACCESS(TRUE, x0[1]) → 676_0_APPE_FIELDACCESS(+(x0[1], -1)) which results in the following constraint:

To summarize, we get the following constraints P_≥ for the following pairs.

• 676_0_APPE_FIELDACCESS(x0) → COND_676_0_APPE_FIELDACCESS(>(x0, 0), x0)
  
  • (x0[0] ≥ 0 ⇒ (U^Increasing(COND_676_0_APPE_FIELDACCESS(>(x0[0], 0), x0[0])), ≥)∧[(-1)Bound*bni_10 + (2)bni_10] + [(2)bni_10]x0[0] ≥ 0∧[(-1)bso_11] ≥ 0)
    
  
  
• COND_676_0_APPE_FIELDACCESS(TRUE, x0) → 676_0_APPE_FIELDACCESS(+(x0, -1))
  
  • ((U^Increasing(676_0_APPE_FIELDACCESS(+(x0[1], -1))), ≥)∧[bni_12] = 0∧0 = 0∧[2 + (-1)bso_13] ≥ 0)
    
  
  

The constraints for P_> respective P_bound are constructed from P_≥ where we just replace every occurence of "t ≥ s" in P_≥ by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for P_bound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation over integers[POLO]:

POL(TRUE) = 0   
POL(FALSE) = 0   
POL(727_1_appE_InvokeMethod(x₁, x₂)) = [-1]   
POL(688_0_appE_Return) = [-1]   
POL(0) = 0   
POL(676_0_APPE_FIELDACCESS(x₁)) = [2]x₁   
POL(COND_676_0_APPE_FIELDACCESS(x₁, x₂)) = [2]x₂   
POL(>(x₁, x₂)) = [-1]   
POL(+(x₁, x₂)) = x₁ + x₂   
POL(-1) = [-1]   

The following pairs are in P_>:

COND_676_0_APPE_FIELDACCESS(TRUE, x0[1]) → 676_0_APPE_FIELDACCESS(+(x0[1], -1))

The following pairs are in P_bound:

For Pair 324_0_CREATELIST_LE(x0) → COND_324_0_CREATELIST_LE(>(x0, 0), x0) the following chains were created:

• We consider the chain 324_0_CREATELIST_LE(x0[0]) → COND_324_0_CREATELIST_LE(>(x0[0], 0), x0[0]), COND_324_0_CREATELIST_LE(TRUE, x0[1]) → 324_0_CREATELIST_LE(+(x0[1], -1)) which results in the following constraint:

  We simplified constraint (1) using rule (IV) which results in the following new constraint:

For Pair COND_324_0_CREATELIST_LE(TRUE, x0) → 324_0_CREATELIST_LE(+(x0, -1)) the following chains were created:

• We consider the chain COND_324_0_CREATELIST_LE(TRUE, x0[1]) → 324_0_CREATELIST_LE(+(x0[1], -1)) which results in the following constraint:

To summarize, we get the following constraints P_≥ for the following pairs.

• 324_0_CREATELIST_LE(x0) → COND_324_0_CREATELIST_LE(>(x0, 0), x0)
  
  • (x0[0] ≥ 0 ⇒ (U^Increasing(COND_324_0_CREATELIST_LE(>(x0[0], 0), x0[0])), ≥)∧[(-1)Bound*bni_8 + (2)bni_8] + [(2)bni_8]x0[0] ≥ 0∧[(-1)bso_9] ≥ 0)
    
  
  
• COND_324_0_CREATELIST_LE(TRUE, x0) → 324_0_CREATELIST_LE(+(x0, -1))
  
  • ((U^Increasing(324_0_CREATELIST_LE(+(x0[1], -1))), ≥)∧[bni_10] = 0∧0 = 0∧[2 + (-1)bso_11] ≥ 0)
    
  
  

The constraints for P_> respective P_bound are constructed from P_≥ where we just replace every occurence of "t ≥ s" in P_≥ by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for P_bound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation over integers[POLO]:

POL(TRUE) = 0   
POL(FALSE) = 0   
POL(324_0_CREATELIST_LE(x₁)) = [2]x₁   
POL(COND_324_0_CREATELIST_LE(x₁, x₂)) = [2]x₂   
POL(>(x₁, x₂)) = [-1]   
POL(0) = 0   
POL(+(x₁, x₂)) = x₁ + x₂   
POL(-1) = [-1]   

The following pairs are in P_>:

COND_324_0_CREATELIST_LE(TRUE, x0[1]) → 324_0_CREATELIST_LE(+(x0[1], -1))

The following pairs are in P_bound:

324_0_CREATELIST_LE(x0[0]) → COND_324_0_CREATELIST_LE(>(x0[0], 0), x0[0])

The following pairs are in P_≥:

324_0_CREATELIST_LE(x0[0]) → COND_324_0_CREATELIST_LE(>(x0[0], 0), x0[0])

There are no usable rules.
