Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

Q DP problem:
The TRS P consists of the following rules:

DIVC_IN_GGA(X1, X2) → U4_GGA(X1, X2, minuscB_in_gga(X1, X2))
U4_GGA(X1, X2, minuscB_out_gga(X1, X2, X4)) → DIVC_IN_GGA(X4, X2)

The TRS R consists of the following rules:

minuscB_in_gga(s(X1), s(X2)) → U11_gga(X1, X2, minuscA_in_gga(X1, X2))
minuscA_in_gga(0, X1) → minuscA_out_gga(0, X1, 0)
minuscA_in_gga(X1, 0) → minuscA_out_gga(X1, 0, X1)
minuscA_in_gga(s(X1), s(X2)) → U10_gga(X1, X2, minuscA_in_gga(X1, X2))
U10_gga(X1, X2, minuscA_out_gga(X1, X2, X3)) → minuscA_out_gga(s(X1), s(X2), X3)
U11_gga(X1, X2, minuscA_out_gga(X1, X2, X3)) → minuscB_out_gga(s(X1), s(X2), X3)

The set Q consists of the following terms:

minuscB_in_gga(x0, x1)
minuscA_in_gga(x0, x1)
U10_gga(x0, x1, x2)
U11_gga(x0, x1, x2)

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

(19) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04,JAR06].

The following pairs can be oriented strictly and are deleted.

U4_GGA(X1, X2, minuscB_out_gga(X1, X2, X4)) → DIVC_IN_GGA(X4, X2)

The remaining pairs can at least be oriented weakly.
Used ordering: Polynomial interpretation [POLO]:

POL(0) = 0   
POL(DIVC_IN_GGA(x₁, x₂)) = 1 + x₁   
POL(U10_gga(x₁, x₂, x₃)) = 1 + x₃   
POL(U11_gga(x₁, x₂, x₃)) = 1 + x₃   
POL(U4_GGA(x₁, x₂, x₃)) = 1 + x₃   
POL(minuscA_in_gga(x₁, x₂)) = x₁   
POL(minuscA_out_gga(x₁, x₂, x₃)) = x₃   
POL(minuscB_in_gga(x₁, x₂)) = x₁   
POL(minuscB_out_gga(x₁, x₂, x₃)) = 1 + x₃   
POL(s(x₁)) = 1 + x₁   

The following usable rules [FROCOS05] with respect to the argument filtering of the ordering [JAR06] were oriented:

minuscB_in_gga(s(X1), s(X2)) → U11_gga(X1, X2, minuscA_in_gga(X1, X2))
minuscA_in_gga(0, X1) → minuscA_out_gga(0, X1, 0)
minuscA_in_gga(X1, 0) → minuscA_out_gga(X1, 0, X1)
minuscA_in_gga(s(X1), s(X2)) → U10_gga(X1, X2, minuscA_in_gga(X1, X2))
U11_gga(X1, X2, minuscA_out_gga(X1, X2, X3)) → minuscB_out_gga(s(X1), s(X2), X3)
U10_gga(X1, X2, minuscA_out_gga(X1, X2, X3)) → minuscA_out_gga(s(X1), s(X2), X3)
