Q of the given QTRS could be proven: (0) QTRS (1) QTRSRRRProof [EQUIVALENT, 33 ms] (2) QTRS (3) RisEmptyProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(j(x, y), y) -> g(f(x, k(y))) f(x, h1(y, z)) -> h2(0, x, h1(y, z)) g(h2(x, y, h1(z, u))) -> h2(s(x), y, h1(z, u)) h2(x, j(y, h1(z, u)), h1(z, u)) -> h2(s(x), y, h1(s(z), u)) i(f(x, h(y))) -> y i(h2(s(x), y, h1(x, z))) -> z k(h(x)) -> h1(0, x) k(h1(x, y)) -> h1(s(x), y) Q is empty. ---------------------------------------- (1) QTRSRRRProof (EQUIVALENT) Used ordering: Knuth-Bendix order [KBO] with precedence:h_1 > i_1 > s_1 > 0 > f_2 > g_1 > j_2 > h2_3 > k_1 > h1_2 and weight map: 0=5 g_1=4 k_1=4 s_1=4 i_1=1 h_1=1 j_2=7 f_2=5 h2_3=0 h1_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: f(j(x, y), y) -> g(f(x, k(y))) f(x, h1(y, z)) -> h2(0, x, h1(y, z)) g(h2(x, y, h1(z, u))) -> h2(s(x), y, h1(z, u)) h2(x, j(y, h1(z, u)), h1(z, u)) -> h2(s(x), y, h1(s(z), u)) i(f(x, h(y))) -> y i(h2(s(x), y, h1(x, z))) -> z k(h(x)) -> h1(0, x) k(h1(x, y)) -> h1(s(x), y) ---------------------------------------- (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
