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

   active(f(x)) -> mark(x)
   top(active(c)) -> top(mark(c))
   top(mark(x)) -> top(check(x))
   check(f(x)) -> f(check(x))
   check(x) -> start(match(f(X), x))
   match(f(x), f(y)) -> f(match(x, y))
   match(X, x) -> proper(x)
   proper(c) -> ok(c)
   proper(f(x)) -> f(proper(x))
   f(ok(x)) -> ok(f(x))
   start(ok(x)) -> found(x)
   f(found(x)) -> found(f(x))
   top(found(x)) -> top(active(x))
   active(f(x)) -> f(active(x))
   f(mark(x)) -> mark(f(x))

Q is empty.

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

Q DP problem:
The TRS P consists of the following rules:

   TOP(active(c)) -> TOP(mark(c))
   TOP(mark(x)) -> TOP(check(x))
   TOP(mark(x)) -> CHECK(x)
   CHECK(f(x)) -> F(check(x))
   CHECK(f(x)) -> CHECK(x)
   CHECK(x) -> START(match(f(X), x))
   CHECK(x) -> MATCH(f(X), x)
   CHECK(x) -> F(X)
