Q DP problem:
The TRS P consists of the following rules:
new_foldl(vx4, vx310, vx3110, :(vx31110, vx31111), ba) → new_foldl(new_flip(vx4, vx310, ba), vx3110, vx31110, vx31111, ba)
The TRS R consists of the following rules:
new_flip(vx4, vx310, ba) → :(vx310, vx4)
The set Q consists of the following terms:
new_flip(x0, x1, x2)
We have to consider all minimal (P,Q,R)-chains.
By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem. From the DPs we obtained the following set of size-change graphs:
- new_foldl(vx4, vx310, vx3110, :(vx31110, vx31111), ba) → new_foldl(new_flip(vx4, vx310, ba), vx3110, vx31110, vx31111, ba)
The graph contains the following edges 3 >= 2, 4 > 3, 4 > 4, 5 >= 5
