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

   active(first(0, X)) -> mark(nil)
   active(first(s(X), cons(Y, Z))) -> mark(cons(Y, first(X, Z)))
   active(from(X)) -> mark(cons(X, from(s(X))))
   mark(first(X1, X2)) -> active(first(mark(X1), mark(X2)))
   mark(0) -> active(0)
   mark(nil) -> active(nil)
   mark(s(X)) -> active(s(mark(X)))
   mark(cons(X1, X2)) -> active(cons(mark(X1), X2))
   mark(from(X)) -> active(from(mark(X)))
   first(mark(X1), X2) -> first(X1, X2)
   first(X1, mark(X2)) -> first(X1, X2)
   first(active(X1), X2) -> first(X1, X2)
   first(X1, active(X2)) -> first(X1, X2)
   s(mark(X)) -> s(X)
   s(active(X)) -> s(X)
   cons(mark(X1), X2) -> cons(X1, X2)
   cons(X1, mark(X2)) -> cons(X1, X2)
   cons(active(X1), X2) -> cons(X1, X2)
   cons(X1, active(X2)) -> cons(X1, X2)
   from(mark(X)) -> from(X)
   from(active(X)) -> from(X)

Q is empty.

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

The TRS P consists of the following rules:

   ACTIVE(first(0, X)) -> MARK(nil)
   ACTIVE(first(s(X), cons(Y, Z))) -> MARK(cons(Y, first(X, Z)))
   ACTIVE(first(s(X), cons(Y, Z))) -> CONS(Y, first(X, Z))
   ACTIVE(first(s(X), cons(Y, Z))) -> FIRST(X, Z)
   ACTIVE(from(X)) -> MARK(cons(X, from(s(X))))
