The TRS R consists of the following rules: from(X) -> cons(X, n__from(n__s(X))) head(cons(X, XS)) -> X 2nd(cons(X, XS)) -> head(activate(XS)) take(0, XS) -> nil take(s(N), cons(X, XS)) -> cons(X, n__take(N, activate(XS))) sel(0, cons(X, XS)) -> X sel(s(N), cons(X, XS)) -> sel(N, activate(XS)) from(X) -> n__from(X) s(X) -> n__s(X) take(X1, X2) -> n__take(X1, X2) activate(n__from(X)) -> from(activate(X)) activate(n__s(X)) -> s(activate(X)) activate(n__take(X1, X2)) -> take(activate(X1), activate(X2)) activate(X) -> X S is empty.

The TRS R consists of the following rules: from(X) -> cons(X, n__from(n__s(X))) head(cons(X, XS)) -> X 2nd(cons(X, XS)) -> head(activate(XS)) take(0, XS) -> nil take(s(N), cons(X, XS)) -> cons(X, n__take(N, activate(XS))) sel(0, cons(X, XS)) -> X sel(s(N), cons(X, XS)) -> sel(N, activate(XS)) from(X) -> n__from(X) s(X) -> n__s(X) take(X1, X2) -> n__take(X1, X2) activate(n__from(X)) -> from(activate(X)) activate(n__s(X)) -> s(activate(X)) activate(n__take(X1, X2)) -> take(activate(X1), activate(X2)) activate(X) -> X S is empty. Rewrite Strategy: FULL ---------------------------------------- (3) DecreasingLoopProof (LOWER BOUND(ID)) The following loop(s) give(s) rise to the lower bound Omega(n^1): The rewrite sequence activate(n__take(X1, X2)) ->^+ take(activate(X1), activate(X2)) gives rise to a decreasing loop by considering the right hand sides subterm at position [0]. The pumping substitution is [X1 / n__take(X1, X2)]. The result substitution is [ ]. popout
