Q DP problem:
The TRS P consists of the following rules:
B(s(x1)) → C(p(s(p(s(x1)))))
C(s(x1)) → A(p(s(p(s(x1)))))
A(s(x1)) → B(p(p(s(s(x1)))))
The TRS R consists of the following rules:
a(s(x1)) → s(s(s(p(s(b(p(p(s(s(x1))))))))))
b(s(x1)) → s(s(s(p(p(s(s(c(p(s(p(s(x1))))))))))))
c(s(x1)) → p(s(p(s(a(p(s(p(s(x1)))))))))
p(p(s(x1))) → p(x1)
p(s(x1)) → x1
The set Q consists of the following terms:
a(s(x0))
b(s(x0))
c(s(x0))
p(s(x0))
We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.
