MAYBE

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

Strict Trs:
  { f(X) -> cons(X, f(g(X)))
  , g(0()) -> s(0())
  , g(s(X)) -> s(s(g(X)))
  , sel(0(), cons(X, Y)) -> X
  , sel(s(X), cons(Y, Z)) -> sel(X, Z) }
Obligation:
  runtime complexity
Answer:

   due to the following reason:
   
   We add the following weak dependency pairs:
   
   Strict DPs:
     { f^#(X) -> c_1(X, f^#(g(X)))
     , g^#(0()) -> c_2()
     , g^#(s(X)) -> c_3(g^#(X))

     , sel^#(s(X), cons(Y, Z)) -> c_5(sel^#(X, Z)) }
   
   and mark the set of starting terms.
   
   We are left with following problem, upon which TcT provides the
   certificate MAYBE.
   
   Strict DPs:

   Answer:
     MAYBE
   
   We estimate the number of application of {2} by applications of
   Pre({2}) = {1,3,4}. Here rules are labeled as follows:
   
     DPs:
       { 1: f^#(X) -> c_1(X, f^#(g(X)))
       , 2: g^#(0()) -> c_2()
       , 3: g^#(s(X)) -> c_3(g^#(X))
       , 4: sel^#(0(), cons(X, Y)) -> c_4(X)
       , 5: sel^#(s(X), cons(Y, Z)) -> c_5(sel^#(X, Z)) }
