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, Cons(vx40, vx41)) -> new_foldr(vx3, vx41) The graph contains the following edges 1 >= 1, 2 > 2 ---------------------------------------- (8) YES
