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

   new_zipWith(wu3, :(wu40, wu41), :(wu50, wu51), h, ba, bb) -> new_zipWith(wu3, wu41, wu51, h, ba, bb)

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_zipWith(wu3, :(wu40, wu41), :(wu50, wu51), h, ba, bb) -> new_zipWith(wu3, wu41, wu51, h, ba, bb)
The graph contains the following edges 1 >= 1, 2 > 2, 3 > 3, 4 >= 4, 5 >= 5, 6 >= 6
