* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          fib(0()) -> s(0())
          fib(s(0())) -> s(0())
          fib(s(s(x))) -> if(true(),0(),s(s(x)),0(),0())
          fibo(0()) -> fib(0())
          fibo(s(0())) -> fib(s(0()))
          fibo(s(s(x))) -> sum(fibo(s(x)),fibo(x))
          if(false(),c,s(s(x)),a,b) -> sum(fibo(a),fibo(b))
          if(true(),c,s(s(x)),a,b) -> if(lt(s(c),s(s(x))),s(c),s(s(x)),b,c)
          lt(x,0()) -> false()
          lt(0(),s(x)) -> true()
          lt(s(x),s(y)) -> lt(x,y)
          sum(x,0()) -> x
          sum(x,s(y)) -> s(sum(x,y))
      - Signature:
          {fib/1,fibo/1,if/5,lt/2,sum/2} / {0/0,false/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {fib,fibo,if,lt,sum} and constructors {0,false,s,true}
