The TRS R consists of the following rules: from(X) -> cons(X, from(s(X))) first(0, Z) -> nil first(s(X), cons(Y, Z)) -> cons(Y, first(X, Z)) sel(0, cons(X, Z)) -> X sel(s(X), cons(Y, Z)) -> sel(X, Z) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (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 (innermost) of the given CpxTRS could be proven to be BOUNDS(INF, INF). The TRS R consists of the following rules: from(X) -> cons(X, from(s(X))) first(0, Z) -> nil first(s(X), cons(Y, Z)) -> cons(Y, first(X, Z)) sel(0, cons(X, Z)) -> X sel(s(X), cons(Y, Z)) -> sel(X, Z) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (3) DecreasingLoopProof (LOWER BOUND(ID)) The following loop(s) give(s) rise to the lower bound Omega(n^1): The rewrite sequence first(s(X), cons(Y, Z)) ->^+ cons(Y, first(X, Z)) gives rise to a decreasing loop by considering the right hand sides subterm at position [1]. The pumping substitution is [X / s(X), Z / cons(Y, Z)]. The result substitution is [ ]. ---------------------------------------- (4) Complex Obligation (BEST) ---------------------------------------- (5) Obligation: Proved the lower bound n^1 for the following obligation: The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(INF, INF). The TRS R consists of the following rules:
