Termination w.r.t. Q of the following Term Rewriting System could be proven:

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

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

average₂(s₁(x), y) -> average₂(x, s₁(y))
average₂(x, s₁(s₁(s₁(y)))) -> s₁(average₂(s₁(x), y))
average₂(0, 0) -> 0
average₂(0, s₁(0)) -> 0
average₂(0, s₁(s₁(0))) -> s₁(0)

Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

AVERAGE₂(x, s₁(s₁(s₁(y)))) -> AVERAGE₂(s₁(x), y)
AVERAGE₂(s₁(x), y) -> AVERAGE₂(x, s₁(y))

The TRS R consists of the following rules:

average₂(s₁(x), y) -> average₂(x, s₁(y))
average₂(x, s₁(s₁(s₁(y)))) -> s₁(average₂(s₁(x), y))
average₂(0, 0) -> 0
average₂(0, s₁(0)) -> 0
average₂(0, s₁(s₁(0))) -> s₁(0)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.

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

AVERAGE₂(x, s₁(s₁(s₁(y)))) -> AVERAGE₂(s₁(x), y)
AVERAGE₂(s₁(x), y) -> AVERAGE₂(x, s₁(y))

The TRS R consists of the following rules:

average₂(s₁(x), y) -> average₂(x, s₁(y))
average₂(x, s₁(s₁(s₁(y)))) -> s₁(average₂(s₁(x), y))

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.

AVERAGE₂(x, s₁(s₁(s₁(y)))) -> AVERAGE₂(s₁(x), y)

The remaining pairs can at least be oriented weakly.

AVERAGE₂(s₁(x), y) -> AVERAGE₂(x, s₁(y))

Used ordering: Polynomial Order [17,21] with Interpretation:

POL( s₁(x₁) ) = x₁ + 2

POL( AVERAGE₂(x₁, x₂) ) = max{0, x₁ + x₂ - 2}

The following usable rules [14] were oriented: none
