The TRS R consists of the following rules: t(N) -> cs(r(q(N)), nt(ns(N))) q(0) -> 0 q(s(X)) -> s(p(q(X), d(X))) d(0) -> 0 d(s(X)) -> s(s(d(X))) p(0, X) -> X p(X, 0) -> X p(s(X), s(Y)) -> s(s(p(X, Y))) f(0, X) -> nil f(s(X), cs(Y, Z)) -> cs(Y, nf(X, a(Z))) t(X) -> nt(X) s(X) -> ns(X) f(X1, X2) -> nf(X1, X2) a(nt(X)) -> t(a(X)) a(ns(X)) -> s(a(X)) a(nf(X1, X2)) -> f(a(X1), a(X2)) a(X) -> X S is empty. Rewrite Strategy: FULL ---------------------------------------- (1) RelTrsToDecreasingLoopProblemProof (LOWER BOUND(ID)) Transformed a relative TRS into a decreasing-loop problem. ---------------------------------------- (2) Obligation: Analyzing the following TRS for decreasing loops: The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(EXP, INF). The TRS R consists of the following rules: t(N) -> cs(r(q(N)), nt(ns(N))) q(0) -> 0 q(s(X)) -> s(p(q(X), d(X))) d(0) -> 0 d(s(X)) -> s(s(d(X))) p(0, X) -> X p(X, 0) -> X p(s(X), s(Y)) -> s(s(p(X, Y))) f(0, X) -> nil f(s(X), cs(Y, Z)) -> cs(Y, nf(X, a(Z))) t(X) -> nt(X) s(X) -> ns(X) f(X1, X2) -> nf(X1, X2) a(nt(X)) -> t(a(X)) a(ns(X)) -> s(a(X)) a(nf(X1, X2)) -> f(a(X1), a(X2)) a(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 a(nt(X)) ->^+ t(a(X)) gives rise to a decreasing loop by considering the right hand sides subterm at position [0]. The pumping substitution is [X / nt(X)]. The result substitution is [ ]. popout
