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

Q restricted rewrite system:
The TRS R consists of the following rules:
p(a(x0), p(a(b(x1)), x2)) → p(a(b(a(x2))), p(a(a(x1)), x2))
Q is empty.
Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
P(a(x0), p(a(b(x1)), x2)) → P(a(b(a(x2))), p(a(a(x1)), x2))
P(a(x0), p(a(b(x1)), x2)) → P(a(a(x1)), x2)
The TRS R consists of the following rules:
p(a(x0), p(a(b(x1)), x2)) → p(a(b(a(x2))), p(a(a(x1)), x2))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.

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.
P(a(x0), p(a(b(x1)), x2)) → P(a(a(x1)), x2)
The remaining pairs can at least be oriented weakly.
P(a(x0), p(a(b(x1)), x2)) → P(a(b(a(x2))), p(a(a(x1)), x2))
Used ordering: Polynomial interpretation [25]:
POL(P(x1, x2)) = x2
POL(a(x1)) = 0
POL(b(x1)) = 0
POL(p(x1, x2)) = 1 + x2
The following usable rules [17] were oriented:
p(a(x0), p(a(b(x1)), x2)) → p(a(b(a(x2))), p(a(a(x1)), x2))

Used ordering: Matrix interpretation [3]:
Non-tuple symbols:
M( p(x1, x2) ) = | | + | | · | x1 | + | | · | x2 |
Tuple symbols:
M( P(x1, x2) ) = | 0 | + | | · | x1 | + | | · | x2 |
Matrix type:
We used a basic matrix type which is not further parametrizeable.
As matrix orders are CE-compatible, we used usable rules w.r.t. argument filtering in the order.
