Q DP problem:
The TRS P consists of the following rules:
new_esEs(Succ(vx29000), Succ(vx310)) → new_esEs(vx29000, vx310)
R is empty.
Q is empty.
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_esEs(Succ(vx29000), Succ(vx310)) → new_esEs(vx29000, vx310)
The graph contains the following edges 1 > 1, 2 > 2
