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

F(s(x1)) → G(s(s(x1)))
G(s(s(x0))) → F(p(s(p(s(x0)))))

The TRS R consists of the following rules:

p(0(x1)) → s(s(0(s(s(p(x1))))))
p(s(0(x1))) → 0(x1)
p(s(s(x1))) → s(p(s(x1)))

The set Q consists of the following terms:

p(0(x0))
p(s(0(x0)))
p(s(s(x0)))

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

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

F(s(x1)) → G(s(s(x1)))
G(s(s(x0))) → F(p(s(p(s(x0)))))

The TRS R consists of the following rules:

p(s(0(x1))) → 0(x1)
p(s(s(x1))) → s(p(s(x1)))

The set Q consists of the following terms:

p(0(x0))
p(s(0(x0)))
p(s(s(x0)))

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].


The following pairs can be oriented strictly and are deleted.


F(s(x1)) → G(s(s(x1)))
The remaining pairs can at least be oriented weakly.

G(s(s(x0))) → F(p(s(p(s(x0)))))
Used ordering: Polynomial Order [21,25] with Interpretation:

POL( p(x1) ) = max{0, x1 - 1}


POL( s(x1) ) = x1 + 1


POL( G(x1) ) = max{0, x1 - 1}


POL( 0(x1) ) = max{0, -1}


POL( F(x1) ) = x1 + 1



The following usable rules [17] were oriented:

p(s(0(x1))) → 0(x1)
p(s(s(x1))) → s(p(s(x1)))
