We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

F(b(b(x, f(y)), z)) → F(b(b(f(a), y), y))

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
F(x1) = F(x1)
b(x1, x2) = b(x1, x2)
f(x1) = f(x1)
a = a

Recursive path order with status [2].
Precedence:

b₂ > F₁ > a
f₁ > F₁ > a

Status:

a: multiset
f₁: multiset
b₂: [2,1]
F₁: multiset

The following usable rules [14] were oriented: none
