There are no usable rules for innermost w.r.t. to the implicit AFS that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(mark(x1))=  x1

  POL(F(x1))=  x1  

resulting in one new DP problem.

On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule

TOP(mark(X)) -> TOP(proper(X))
five new Dependency Pairs are created:

TOP(mark(f(X''))) -> TOP(f(proper(X'')))
TOP(mark(0)) -> TOP(ok(0))
TOP(mark(cons(X1', X2'))) -> TOP(cons(proper(X1'), proper(X2')))
TOP(mark(s(X''))) -> TOP(s(proper(X'')))
TOP(mark(p(X''))) -> TOP(p(proper(X'')))

The transformation is resulting in one new DP problem:

On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule

TOP(ok(X)) -> TOP(active(X))
seven new Dependency Pairs are created:

TOP(ok(f(0))) -> TOP(mark(cons(0, f(s(0)))))
TOP(ok(f(s(0)))) -> TOP(mark(f(p(s(0)))))
TOP(ok(p(s(0)))) -> TOP(mark(0))
TOP(ok(f(X''))) -> TOP(f(active(X'')))
TOP(ok(cons(X1', X2'))) -> TOP(cons(active(X1'), X2'))
TOP(ok(s(X''))) -> TOP(s(active(X'')))
TOP(ok(p(X''))) -> TOP(p(active(X'')))

The transformation is resulting in one new DP problem:

The following dependency pair can be strictly oriented:

Additionally, the following usable rules for innermost w.r.t. to the implicit AFS can be oriented:

p(mark(X)) -> mark(p(X))
p(ok(X)) -> ok(p(X))
s(mark(X)) -> mark(s(X))
s(ok(X)) -> ok(s(X))

cons(ok(X1), ok(X2)) -> ok(cons(X1, X2))
f(mark(X)) -> mark(f(X))
f(ok(X)) -> ok(f(X))


Used ordering: Polynomial ordering with Polynomial interpretation:
