Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B1(a(A(x0))) → B1(c(a(a(B(x0))))) at position [0] we obtained the following new rules:

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule B1(a(A(y0))) → B1(c(c(A(y0)))) at position [0] we obtained the following new rules:

B1(a(A(y0))) → B1(A(y0))
