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

   plus(x, 0) -> x
   plus(x, s(y)) -> s(plus(x, y))
   times(0, y) -> 0
   times(x, 0) -> 0
   times(s(x), y) -> plus(times(x, y), y)
   p(s(s(x))) -> s(p(s(x)))
   p(s(0)) -> 0
   fac(s(x)) -> times(fac(p(s(x))), s(x))

Q is empty.

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

(1) DependencyPairsProof (EQUIVALENT)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

(2)
Obligation:
Q DP problem:
The TRS P consists of the following rules:

   PLUS(x, s(y)) -> PLUS(x, y)
   TIMES(s(x), y) -> PLUS(times(x, y), y)
   TIMES(s(x), y) -> TIMES(x, y)
   P(s(s(x))) -> P(s(x))
   FAC(s(x)) -> TIMES(fac(p(s(x))), s(x))
   FAC(s(x)) -> FAC(p(s(x)))
   FAC(s(x)) -> P(s(x))

The TRS R consists of the following rules:

   plus(x, 0) -> x
   plus(x, s(y)) -> s(plus(x, y))
   times(0, y) -> 0
   times(x, 0) -> 0
   times(s(x), y) -> plus(times(x, y), y)
   p(s(s(x))) -> s(p(s(x)))
   p(s(0)) -> 0
