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:

a(b(a(x))) → b(a(b(x)))

Q is empty.

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

a(b(a(x))) → b(a(b(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:

A(b(a(x))) → A(b(x))

The TRS R consists of the following rules:

a(b(a(x))) → b(a(b(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:

A(b(a(x))) → A(b(x))

The TRS R consists of the following rules:

a(b(a(x))) → b(a(b(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.


A(b(a(x))) → A(b(x))
The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
A(x1)  =  A(x1)
b(x1)  =  b(x1)
a(x1)  =  a(x1)

Lexicographic path order with status [19].
Precedence:
b1 > A1
a1 > A1

Status:
a1: multiset
b1: [1]
A1: [1]

The following usable rules [14] were oriented: none

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

a(b(a(x))) → b(a(b(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.
