MAYBE

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

Strict Trs:
  { a__f(X1, X2) -> f(X1, X2)
  , a__f(g(X), Y) -> a__f(mark(X), f(g(X), Y))
  , mark(g(X)) -> g(mark(X))
  , mark(f(X1, X2)) -> a__f(mark(X1), X2) }
Obligation:
  runtime complexity

3) 'Innermost Weak Dependency Pairs (timeout of 60 seconds)' failed
   due to the following reason:
   
   We add the following weak dependency pairs:
   
   Strict DPs:
     { a__f^#(X1, X2) -> c_1(X1, X2)
     , a__f^#(g(X), Y) -> c_2(a__f^#(mark(X), f(g(X), Y)))

   and mark the set of starting terms.
   
   We are left with following problem, upon which TcT provides the
   certificate MAYBE.
   
   Strict DPs:
