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

   new_foldr(vx3, :(vx40, vx41), h) -> new_foldr(vx3, vx41, h)

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_foldr(vx3, :(vx40, vx41), h) -> new_foldr(vx3, vx41, h)
The graph contains the following edges 1 >= 1, 2 > 2, 3 >= 3
