top₁(ok₁(X)) -> top₁(active₁(X))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

TOP₁(mark₁(X)) -> TOP₁(proper₁(X))

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( h₁(x₁) ) = max{0, 2x₁ - 2}

POL( mark₁(x₁) ) = 2

POL( f₁(x₁) ) = max{0, 2x₁ - 2}

POL( TOP₁(x₁) ) = max{0, 2x₁ - 1}

POL( ok₁(x₁) ) = 2x₁ + 2

POL( g₁(x₁) ) = x₁

POL( proper₁(x₁) ) = max{0, -2}

The following usable rules [14] were oriented:

proper₁(f₁(X)) -> f₁(proper₁(X))
f₁(mark₁(X)) -> mark₁(f₁(X))
proper₁(g₁(X)) -> g₁(proper₁(X))
f₁(ok₁(X)) -> ok₁(f₁(X))
h₁(mark₁(X)) -> mark₁(h₁(X))
g₁(ok₁(X)) -> ok₁(g₁(X))
h₁(ok₁(X)) -> ok₁(h₁(X))
proper₁(h₁(X)) -> h₁(proper₁(X))

The TRS R consists of the following rules:

active₁(f₁(X)) -> mark₁(g₁(h₁(f₁(X))))
active₁(f₁(X)) -> f₁(active₁(X))
active₁(h₁(X)) -> h₁(active₁(X))
f₁(mark₁(X)) -> mark₁(f₁(X))

g₁(ok₁(X)) -> ok₁(g₁(X))
h₁(ok₁(X)) -> ok₁(h₁(X))

top₁(ok₁(X)) -> top₁(active₁(X))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
