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

f(f(x)) → f(c(f(x)))
f(f(x)) → f(d(f(x)))
g(c(x)) → x
g(d(x)) → x
g(c(0)) → g(d(1))
g(c(1)) → g(d(0))

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:

F(f(x)) → F(c(f(x)))
G(c(1)) → G(d(0))
F(f(x)) → F(d(f(x)))
G(c(0)) → G(d(1))

The TRS R consists of the following rules:

f(f(x)) → f(c(f(x)))
f(f(x)) → f(d(f(x)))
