Q DP problem:
P is empty.
The TRS R consists of the following rules:

din₁(der₁(plus₂(X, Y))) -> u21₃(din₁(der₁(X)), X, Y)
u21₃(dout₁(DX), X, Y) -> u22₄(din₁(der₁(Y)), X, Y, DX)
u22₄(dout₁(DY), X, Y, DX) -> dout₁(plus₂(DX, DY))
din₁(der₁(times₂(X, Y))) -> u31₃(din₁(der₁(X)), X, Y)
u31₃(dout₁(DX), X, Y) -> u32₄(din₁(der₁(Y)), X, Y, DX)
u32₄(dout₁(DY), X, Y, DX) -> dout₁(plus₂(times₂(X, DY), times₂(Y, DX)))
din₁(der₁(der₁(X))) -> u41₂(din₁(der₁(X)), X)
u41₂(dout₁(DX), X) -> u42₃(din₁(der₁(DX)), X, DX)
u42₃(dout₁(DDX), X, DX) -> dout₁(DDX)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
