By [CS_Inn] we can switch to innermost. ---------------------------------------- (2) Obligation: Context-sensitive rewrite system: The TRS R consists of the following rules: 2nd(cons(X, cons(Y, Z))) -> Y from(X) -> cons(X, from(s(X))) The replacement map contains the following entries: 2nd: {1} cons: {1} from: {1} s: {1} Innermost Strategy. ---------------------------------------- (3) CSDependencyPairsProof (EQUIVALENT) Using Improved CS-DPs [LPAR08] we result in the following initial Q-CSDP problem. ---------------------------------------- (4) Obligation: Q-restricted context-sensitive dependency pair problem: The symbols in {2nd_1, from_1, s_1, 2ND_1, FROM_1} are replacing on all positions. For all symbols f in {cons_2} we have mu(f) = {1}. The symbols in {U_1} are not replacing on any position. The collapsing dependency pairs are DP_c: 2ND(cons(X, cons(Y, Z))) -> Y The hidden terms of R are: from(s(x0)) Every hiding context is built from: aprove.DPFramework.CSDPProblem.QCSDPProblem$1@6e914b66 aprove.DPFramework.CSDPProblem.QCSDPProblem$1@46a6d3f8 Hence, the new unhiding pairs DP_u are : 2ND(cons(X, cons(Y, Z))) -> U(Y) U(s(x_0)) -> U(x_0) U(from(x_0)) -> U(x_0) U(from(s(x0))) -> FROM(s(x0)) The TRS R consists of the following rules: 2nd(cons(X, cons(Y, Z))) -> Y from(X) -> cons(X, from(s(X))) The set Q consists of the following terms: 2nd(cons(x0, cons(x1, x2)))
