MAYBE

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

Strict Trs:
  { terms(N) -> cons(recip(sqr(N)), terms(s(N)))
  , sqr(s(X)) -> s(add(sqr(X), dbl(X)))
  , sqr(0()) -> 0()
  , add(s(X), Y) -> s(add(X, Y))
  , add(0(), X) -> X
  , dbl(s(X)) -> s(s(dbl(X)))
  , dbl(0()) -> 0()
  , first(s(X), cons(Y, Z)) -> cons(Y, first(X, Z))
  , first(0(), X) -> nil()
  , half(s(s(X))) -> s(half(X))
  , half(s(0())) -> 0()
  , half(0()) -> 0()
  , half(dbl(X)) -> X }
Obligation:
  innermost runtime complexity

         -----------------------------
         1) 'Bounds with minimal-enrichment and initial automaton 'match''
            failed due to the following reason:
            
            match-boundness of the problem could not be verified.
         
         2) 'Bounds with perSymbol-enrichment and initial automaton 'match''
            failed due to the following reason:
