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:

and3(not1(not1(x)), y, not1(z)) -> and3(y, band2(x, z), x)

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

and3(not1(not1(x)), y, not1(z)) -> and3(y, band2(x, z), x)

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:

AND3(not1(not1(x)), y, not1(z)) -> AND3(y, band2(x, z), x)

The TRS R consists of the following rules:

and3(not1(not1(x)), y, not1(z)) -> and3(y, band2(x, z), x)

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

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

AND3(not1(not1(x)), y, not1(z)) -> AND3(y, band2(x, z), x)

The TRS R consists of the following rules:

and3(not1(not1(x)), y, not1(z)) -> and3(y, band2(x, z), 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.


AND3(not1(not1(x)), y, not1(z)) -> AND3(y, band2(x, z), x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( not1(x1) ) = x1 + 3


POL( band2(x1, x2) ) = max{0, -3}


POL( AND3(x1, ..., x3) ) = 2x1 + 2x2



The following usable rules [14] were oriented: none

Q DP problem:
P is empty.
The TRS R consists of the following rules:

and3(not1(not1(x)), y, not1(z)) -> and3(y, band2(x, z), 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.
