----------------------------------------

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   lt(0, s(x)) -> true
   lt(x, 0) -> false
   lt(s(x), s(y)) -> lt(x, y)
   fibo(0) -> fib(0)
   fibo(s(0)) -> fib(s(0))
   fibo(s(s(x))) -> sum(fibo(s(x)), fibo(x))
   fib(0) -> s(0)
   fib(s(0)) -> s(0)
   fib(s(s(x))) -> if(true, 0, s(s(x)), 0, 0)
   if(true, c, s(s(x)), a, b) -> if(lt(s(c), s(s(x))), s(c), s(s(x)), b, c)
   if(false, c, s(s(x)), a, b) -> sum(fibo(a), fibo(b))
   sum(x, 0) -> x
   sum(x, s(y)) -> s(sum(x, y))

Q is empty.

----------------------------------------

(1) Overlay + Local Confluence (EQUIVALENT)
The TRS is overlay and locally confluent. By [NOC] we can switch to innermost.
