Q restricted rewrite system:
The TRS R consists of the following rules:
f(f(X)) → c
c → d
h(X) → c
Q is empty.
Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
F(f(X)) → C
H(X) → C
The TRS R consists of the following rules:
f(f(X)) → c
c → d
h(X) → c
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
