The conditional TRS C consists of the following conditional rules: f(x, x') -> g(y, y) <= x -> y, x' -> y h(x, x', x'') -> c <= x -> y, x' -> y, x'' -> y ---------------------------------------- (1) CTRSToQTRSProof (SOUND) The conditional rules have been transormed into unconditional rules according to [CTRS,AAECCNOC]. ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(x, x') -> U1(x, x') U1(y, x') -> U2(x', y) U2(y, y) -> g(y, y) h(x, x', x'') -> U3(x, x', x'') U3(y, x', x'') -> U4(x', x'') U4(y, x'') -> U5(x'') U5(y) -> c Q is empty. ---------------------------------------- (3) QTRSRRRProof (EQUIVALENT) Used ordering: Knuth-Bendix order [KBO] with precedence:h_3 > U3_3 > U4_2 > U5_1 > c > f_2 > U1_2 > U2_2 > g_2 and weight map: c=3 U5_1=2 f_2=0 U1_2=0 U2_2=0 g_2=0 h_3=0 U3_3=0 U4_2=1 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(x, x') -> U1(x, x') U1(y, x') -> U2(x', y) U2(y, y) -> g(y, y) h(x, x', x'') -> U3(x, x', x'') U3(y, x', x'') -> U4(x', x'') U4(y, x'') -> U5(x'') U5(y) -> c ---------------------------------------- (4) Obligation: Q restricted rewrite system: R is empty. Q is empty. ---------------------------------------- (5) RisEmptyProof (EQUIVALENT) The TRS R is empty. Hence, termination is trivially proven. ---------------------------------------- popout
