MAYBE

'epo* (timeout of 60.0 seconds)'
--------------------------------
Answer:           MAYBE
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  le(s(x), 0()) -> false()
     , le(0(), y) -> true()
     , le(s(x), s(y)) -> le(x, y)
     , double(0()) -> 0()
     , double(s(x)) -> s(s(double(x)))
     , log(0()) -> logError()
     , log(s(x)) -> loop(s(x), s(0()), 0())
     , loop(x, s(y), z) -> if(le(x, s(y)), x, s(y), z)
     , if(true(), x, y, z) -> z
     , if(false(), x, y, z) -> loop(x, double(y), s(z))}

Proof Output:    
  The input cannot be shown compatible
