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

a(a(b(x1))) → b(c(b(a(a(a(x1))))))
a(c(x1)) → x1

Q is empty.

The TRS is overlay and locally confluent. By [19] we can switch to innermost.

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

a(a(b(x1))) → b(c(b(a(a(a(x1))))))
a(c(x1)) → x1

The set Q consists of the following terms:

a(a(b(x0)))
a(c(x0))


Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

A(a(b(x1))) → A(x1)
A(a(b(x1))) → A(a(x1))
A(a(b(x1))) → A(a(a(x1)))

The TRS R consists of the following rules:

a(a(b(x1))) → b(c(b(a(a(a(x1))))))
a(c(x1)) → x1

The set Q consists of the following terms:

a(a(b(x0)))
a(c(x0))

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

We have to consider all minimal (P,Q,R)-chains.
We use the modular non-overlap check [17] to decrease Q to the empty set.
