The TRS R consists of the following rules: is_empty(nil) -> true is_empty(cons(x, l)) -> false hd(cons(x, l)) -> x tl(cons(x, l)) -> l append(l1, l2) -> ifappend(l1, l2, is_empty(l1)) ifappend(l1, l2, true) -> l2 ifappend(l1, l2, false) -> cons(hd(l1), append(tl(l1), l2)) S is empty.

The TRS R consists of the following rules: is_empty(nil) -> true [1] is_empty(cons(x, l)) -> false [1] hd(cons(x, l)) -> x [1] tl(cons(x, l)) -> l [1] append(l1, l2) -> ifappend(l1, l2, is_empty(l1)) [1] ifappend(l1, l2, true) -> l2 [1] ifappend(l1, l2, false) -> cons(hd(l1), append(tl(l1), l2)) [1] The TRS has the following type information: is_empty :: nil:cons -> true:false nil :: nil:cons true :: true:false cons :: hd -> nil:cons -> nil:cons false :: true:false hd :: nil:cons -> hd tl :: nil:cons -> nil:cons append :: nil:cons -> nil:cons -> nil:cons ifappend :: nil:cons -> nil:cons -> true:false -> nil:cons Rewrite Strategy: INNERMOST popout
