Q DP problem:
The TRS P consists of the following rules:

   new_primEqNat(Main.Succ(vz30000), Main.Succ(vz40000)) -> new_primEqNat(vz30000, vz40000)

R is empty.
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
----------------------------------------

(7) QDPSizeChangeProof (EQUIVALENT)
By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] 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(Main.Succ(vz30000), Main.Succ(vz40000)) -> new_primEqNat(vz30000, vz40000)
The graph contains the following edges 1 > 1, 2 > 2
