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

f1(X) -> if3(X, c, f1(true))

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

f1(X) -> if3(X, c, f1(true))
if3(true, X, Y) -> X
if3(false, X, Y) -> Y

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

F1(X) -> F1(true)
F1(X) -> IF3(X, c, f1(true))

The TRS R consists of the following rules:

f1(X) -> if3(X, c, f1(true))
if3(true, X, Y) -> X
if3(false, X, Y) -> Y

The set Q consists of the following terms:

f1(x0)
if3(true, x0, x1)
if3(false, x0, x1)

We have to consider all minimal (P,Q,R)-chains.
