MAYBE

'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  half(0()) -> 0()
     , half(s(0())) -> 0()
     , half(s(s(x))) -> s(half(x))
     , lastbit(0()) -> 0()
     , lastbit(s(0())) -> s(0())
     , lastbit(s(s(x))) -> lastbit(x)
     , zero(0()) -> true()
     , zero(s(x)) -> false()
     , conv(x) -> conviter(x, cons(0(), nil()))
     , conviter(x, l) -> if(zero(x), x, l)
     , if(true(), x, l) -> l
     , if(false(), x, l) -> conviter(half(x), cons(lastbit(x), l))}

Proof Output:    
  The input cannot be shown compatible
