From the DPs we obtained the following set of size-change graphs: *new_gtGtEs(:(vy510, vy511), vy3, vy40, h, ba, bb) -> new_gtGtEs(vy511, vy3, vy40, h, ba, bb) The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3, 4 >= 4, 5 >= 5, 6 >= 6 ---------------------------------------- (14) YES ---------------------------------------- (15) Obligation: Q DP problem: The TRS P consists of the following rules: new_psPs(:(vy70, vy71), vy6, h) -> new_psPs(vy71, vy6, h) R is empty. Q is empty. We have to consider all minimal (P,Q,R)-chains. ---------------------------------------- (16) 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_psPs(:(vy70, vy71), vy6, h) -> new_psPs(vy71, vy6, h) The graph contains the following edges 1 > 1, 2 >= 2, 3 >= 3 ---------------------------------------- (17) YES
