Hence, by the usable rules processor [LPAR04] we can delete all non-usable rules [FROCOS05] from R. 13.18/5.10 ---------------------------------------- 13.18/5.10 13.18/5.10 (39) 13.18/5.10 Obligation: 13.18/5.10 Q DP problem: 13.18/5.10 The TRS P consists of the following rules: 13.18/5.10 13.18/5.10 new_isPrefixOf0(wu16, wu17, :(wu180, wu181), wu19, ba) -> new_isPrefixOf0(:(wu17, wu16), wu180, wu181, wu19, ba) 13.18/5.10 13.18/5.10 R is empty. 13.18/5.10 The set Q consists of the following terms: 13.18/5.10 13.18/5.10 new_flip(x0, x1, x2) 13.18/5.10 13.18/5.10 We have to consider all minimal (P,Q,R)-chains. 13.18/5.10 ---------------------------------------- 13.18/5.10 13.18/5.10 (40) QReductionProof (EQUIVALENT) 13.18/5.10 We deleted the following terms from Q as each root-symbol of these terms does neither occur in P nor in R.[THIEMANN]. 13.18/5.10 13.18/5.10 new_flip(x0, x1, x2) 13.18/5.10 13.18/5.10 13.18/5.10 ---------------------------------------- 13.18/5.10 13.18/5.10 (41) 13.18/5.10 Obligation: 13.18/5.10 Q DP problem: 13.18/5.10 The TRS P consists of the following rules: 13.18/5.10 13.18/5.10 new_isPrefixOf0(wu16, wu17, :(wu180, wu181), wu19, ba) -> new_isPrefixOf0(:(wu17, wu16), wu180, wu181, wu19, ba) 13.18/5.10 13.18/5.10 R is empty. 13.18/5.10 Q is empty. 13.18/5.10 We have to consider all minimal (P,Q,R)-chains. 13.18/5.10 ---------------------------------------- 13.18/5.10 13.18/5.10 (42) QDPSizeChangeProof (EQUIVALENT) 13.18/5.10 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. 13.18/5.10 13.18/5.10 From the DPs we obtained the following set of size-change graphs: 13.18/5.10 *new_isPrefixOf0(wu16, wu17, :(wu180, wu181), wu19, ba) -> new_isPrefixOf0(:(wu17, wu16), wu180, wu181, wu19, ba) 13.18/5.10 The graph contains the following edges 3 > 2, 3 > 3, 4 >= 4, 5 >= 5 13.18/5.10 13.18/5.10 13.18/5.10 ---------------------------------------- 13.18/5.10 13.18/5.10 (43) 13.18/5.10 YES 13.18/5.14 EOF
