The following dependency pair can be strictly oriented:

SEL(ok(X1), ok(X2)) -> SEL(X1, X2)

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(SEL(x₁, x₂)) = x₁

POL(mark(x₁)) = x₁

POL(ok(x₁)) = 1 + x₁

resulting in one new DP problem.

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(mark(x₁)) = 0

POL(ok(x₁)) = 1 + x₁

POL(CONS(x₁, x₂)) = x₂

resulting in one new DP problem.

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(FIRST(x₁, x₂)) = x₁

The following dependency pair can be strictly oriented:

QUOTE1(ok(X)) -> QUOTE1(X)

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(QUOTE1(x₁)) = x₁

POL(ok(x₁)) = 1 + x₁

resulting in one new DP problem.

The following dependency pair can be strictly oriented:

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(FCONS(x₁, x₂)) = x₁

POL(mark(x₁)) = 1 + x₁

top(mark(X)) -> top(proper(X))

The following dependency pair can be strictly oriented:

PROPER(unquote(X)) -> PROPER(X)

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

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(PROPER(x₁)) = x₁

POL(unquote(x₁)) = 1 + x₁

resulting in one new DP problem.
