MAYBE

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict Trs:
  { from(x) -> cons(x, cons(nil(), from(s(x))))
  , cons(s(x), xs) -> nil() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

We add following dependency tuples:

Strict DPs:
  { from^#(x) ->
    c_1(cons^#(x, cons(nil(), from(s(x)))),
        cons^#(nil(), from(s(x))),
        from^#(s(x)))
  , cons^#(s(x), xs) -> c_2() }

and mark the set of starting terms.

  { from^#(x) ->
    c_1(cons^#(x, cons(nil(), from(s(x)))),
        cons^#(nil(), from(s(x))),
        from^#(s(x)))
  , cons^#(s(x), xs) -> c_2() }

We estimate the number of application of {2} by applications of
Pre({2}) = {1}. Here rules are labeled as follows:

  DPs:
    { 1: from^#(x) ->
         c_1(cons^#(x, cons(nil(), from(s(x)))),
             cons^#(nil(), from(s(x))),
             from^#(s(x)))
    , 2: cons^#(s(x), xs) -> c_2() }

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict DPs:
  { from^#(x) ->
    c_1(cons^#(x, cons(nil(), from(s(x)))),
        cons^#(nil(), from(s(x))),
        from^#(s(x))) }
Weak DPs: { cons^#(s(x), xs) -> c_2() }
Weak Trs:
  { from(x) -> cons(x, cons(nil(), from(s(x))))
  , cons(s(x), xs) -> nil() }

  MAYBE

The following weak DPs constitute a sub-graph of the DG that is
closed under successors. The DPs are removed.

{ cons^#(s(x), xs) -> c_2() }

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict DPs:
  { from^#(x) ->
    c_1(cons^#(x, cons(nil(), from(s(x)))),
        cons^#(nil(), from(s(x))),
        from^#(s(x))) }
Weak Trs:
  { from(x) -> cons(x, cons(nil(), from(s(x))))
  , cons(s(x), xs) -> nil() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

Due to missing edges in the dependency-graph, the right-hand sides
of following rules could be simplified:

  { from^#(x) ->
    c_1(cons^#(x, cons(nil(), from(s(x)))),
        cons^#(nil(), from(s(x))),
        from^#(s(x))) }

We are left with following problem, upon which TcT provides the
certificate MAYBE.

Strict DPs: { from^#(x) -> c_1(from^#(s(x))) }
Weak Trs:
  { from(x) -> cons(x, cons(nil(), from(s(x))))
  , cons(s(x), xs) -> nil() }
Obligation:
  innermost runtime complexity
Answer:
  MAYBE

No rule is usable, rules are removed from the input problem.
