Obligation:
The Runtime Complexity (full) of the given CpxTRS could be proven to be BOUNDS(n^2, INF).


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))

S is empty.

The TRS R consists of the following rules:

   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))

S is empty.
