Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 30 ms] (2) QTRS (3) RisEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: concat(leaf, Y) -> Y concat(cons(U, V), Y) -> cons(U, concat(V, Y)) lessleaves(X, leaf) -> false lessleaves(leaf, cons(W, Z)) -> true lessleaves(cons(U, V), cons(W, Z)) -> lessleaves(concat(U, V), concat(W, Z)) Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Knuth-Bendix order [KBO] with precedence:lessleaves_2 > true > false > concat_2 > cons_2 > leaf and weight map: leaf=1 false=2 true=4 concat_2=0 cons_2=1 lessleaves_2=0 The variable weight is 1With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly: concat(leaf, Y) -> Y concat(cons(U, V), Y) -> cons(U, concat(V, Y)) lessleaves(X, leaf) -> false lessleaves(leaf, cons(W, Z)) -> true lessleaves(cons(U, V), cons(W, Z)) -> lessleaves(concat(U, V), concat(W, Z)) ---------------------------------------- (2) Obligation: Q restricted rewrite system: R is empty. Q is empty. ---------------------------------------- (3) RisEmptyProof (EQUIVALENT) The TRS R is empty. Hence, termination is trivially proven. ---------------------------------------- (4) YES popout
