Relative term rewrite system:
The relative TRS consists of the following R rules:

   d(n(x1)) -> d(x1)
   d(o(x1)) -> d(x1)
   o(u(x1)) -> u(x1)

The relative TRS consists of the following S rules:

   t(u(x1)) -> t(c(d(x1)))
   d(f(x1)) -> f(d(x1))
   d(g(x1)) -> u(g(x1))
   f(u(x1)) -> u(f(x1))
   n(u(x1)) -> u(x1)
   f(x1) -> f(n(x1))
   t(x1) -> t(c(n(x1)))
   c(n(x1)) -> n(c(x1))
   c(o(x1)) -> o(c(x1))
   c(o(x1)) -> o(x1)
   c(f(x1)) -> f(c(x1))
   c(u(x1)) -> u(c(x1))
   c(d(x1)) -> d(c(x1))


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

(1) RelTRSRRRProof (EQUIVALENT)
We used the following monotonic ordering for rule removal:
Polynomial interpretation [POLO]:

   POL(c(x_1)) = x_1
   POL(d(x_1)) = x_1
   POL(f(x_1)) = x_1
   POL(g(x_1)) = x_1
   POL(n(x_1)) = x_1
   POL(o(x_1)) = 1 + x_1
   POL(t(x_1)) = x_1
   POL(u(x_1)) = x_1
With this ordering the following rules can be removed [MATRO] because they are oriented strictly:
Rules from R:

   d(o(x1)) -> d(x1)
   o(u(x1)) -> u(x1)
Rules from S:
none

   f(u(x1)) -> u(f(x1))
   n(u(x1)) -> u(x1)
   f(x1) -> f(n(x1))
   t(x1) -> t(c(n(x1)))
   c(n(x1)) -> n(c(x1))
   c(o(x1)) -> o(c(x1))
