Q DP problem:
The TRS P consists of the following rules:
new_primEqNat(Succ(vx37000), Succ(vx430)) → new_primEqNat(vx37000, vx430)
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_primEqNat(Succ(vx37000), Succ(vx430)) → new_primEqNat(vx37000, vx430)
The graph contains the following edges 1 > 1, 2 > 2
