The TRS R consists of the following rules: a__from(X) -> cons(mark(X), from(s(X))) a__head(cons(X, XS)) -> mark(X) a__2nd(cons(X, XS)) -> a__head(mark(XS)) a__take(0, XS) -> nil a__take(s(N), cons(X, XS)) -> cons(mark(X), take(N, XS)) a__sel(0, cons(X, XS)) -> mark(X) a__sel(s(N), cons(X, XS)) -> a__sel(mark(N), mark(XS)) mark(from(X)) -> a__from(mark(X)) mark(head(X)) -> a__head(mark(X)) mark(2nd(X)) -> a__2nd(mark(X)) mark(take(X1, X2)) -> a__take(mark(X1), mark(X2)) mark(sel(X1, X2)) -> a__sel(mark(X1), mark(X2)) mark(cons(X1, X2)) -> cons(mark(X1), X2) mark(s(X)) -> s(mark(X)) mark(0) -> 0 mark(nil) -> nil a__from(X) -> from(X) a__head(X) -> head(X) a__2nd(X) -> 2nd(X) a__take(X1, X2) -> take(X1, X2) a__sel(X1, X2) -> sel(X1, X2) 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: a__from(X) -> cons(mark(X), from(s(X))) a__head(cons(X, XS)) -> mark(X) a__2nd(cons(X, XS)) -> a__head(mark(XS)) a__take(0, XS) -> nil a__take(s(N), cons(X, XS)) -> cons(mark(X), take(N, XS)) a__sel(0, cons(X, XS)) -> mark(X) a__sel(s(N), cons(X, XS)) -> a__sel(mark(N), mark(XS)) mark(from(X)) -> a__from(mark(X)) mark(head(X)) -> a__head(mark(X)) mark(2nd(X)) -> a__2nd(mark(X)) mark(take(X1, X2)) -> a__take(mark(X1), mark(X2)) mark(sel(X1, X2)) -> a__sel(mark(X1), mark(X2)) mark(cons(X1, X2)) -> cons(mark(X1), X2) mark(s(X)) -> s(mark(X)) mark(0) -> 0 mark(nil) -> nil a__from(X) -> from(X) a__head(X) -> head(X) a__2nd(X) -> 2nd(X) a__take(X1, X2) -> take(X1, X2) a__sel(X1, X2) -> sel(X1, X2) S is empty.
