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

   times(x, y) -> sum(generate(x, y))
   generate(x, y) -> gen(x, y, 0)
   gen(x, y, z) -> if(ge(z, x), x, y, z)
   if(true, x, y, z) -> nil
   if(false, x, y, z) -> cons(y, gen(x, y, s(z)))
   sum(nil) -> 0
   sum(cons(0, xs)) -> sum(xs)
   sum(cons(s(x), xs)) -> s(sum(cons(x, xs)))
   ge(x, 0) -> true
   ge(0, s(y)) -> false
   ge(s(x), s(y)) -> ge(x, y)

Q is empty.

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

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

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   times(x, y) -> sum(generate(x, y))
   generate(x, y) -> gen(x, y, 0)
   gen(x, y, z) -> if(ge(z, x), x, y, z)
   if(true, x, y, z) -> nil
   if(false, x, y, z) -> cons(y, gen(x, y, s(z)))
   sum(nil) -> 0
   sum(cons(0, xs)) -> sum(xs)
   sum(cons(s(x), xs)) -> s(sum(cons(x, xs)))
   ge(x, 0) -> true
   ge(0, s(y)) -> false
   ge(s(x), s(y)) -> ge(x, y)

The set Q consists of the following terms:

   times(x0, x1)
   generate(x0, x1)
   gen(x0, x1, x2)
   if(true, x0, x1, x2)
   if(false, x0, x1, x2)
   sum(nil)
   sum(cons(0, x0))
   sum(cons(s(x0), x1))
   ge(x0, 0)
   ge(0, s(x0))
   ge(s(x0), s(x1))
