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

PB_IN_AGGAAA(T28, T26, T27, cons(T119, T120), T118, cons(T121, T122)) → U3_AGGAAA(T28, T26, T27, T119, T120, T118, T121, T122, row2colC_in_aggaa(T28, T26, T27, cons(T119, T120), T118))
U3_AGGAAA(T28, T26, T27, T119, T120, T118, T121, T122, row2colC_out_aggaa(T28, T26, T27, cons(T119, T120), T118)) → PB_IN_AGGAAA(T121, T119, T120, X185, X186, T122)

The TRS R consists of the following rules:

row2colC_in_aggaa(cons(T57, T61), cons(T57, T59), T60, cons(T59, X91), cons(nil, X92)) → U6_aggaa(T57, T61, T59, T60, X91, X92, row2colA_in_agaa(T61, T60, X91, X92))
U6_aggaa(T57, T61, T59, T60, X91, X92, row2colA_out_agaa(T61, T60, X91, X92)) → row2colC_out_aggaa(cons(T57, T61), cons(T57, T59), T60, cons(T59, X91), cons(nil, X92))
row2colA_in_agaa(cons(T82, T86), cons(cons(T82, T84), T85), cons(T84, X139), cons(nil, X140)) → U1_agaa(T82, T86, T84, T85, X139, X140, row2colA_in_agaa(T86, T85, X139, X140))
row2colA_in_agaa(nil, nil, nil, nil) → row2colA_out_agaa(nil, nil, nil, nil)
U1_agaa(T82, T86, T84, T85, X139, X140, row2colA_out_agaa(T86, T85, X139, X140)) → row2colA_out_agaa(cons(T82, T86), cons(cons(T82, T84), T85), cons(T84, X139), cons(nil, X140))

The argument filtering Pi contains the following mapping:
cons(x1, x2)  =  cons(x1, x2)
row2colC_in_aggaa(x1, x2, x3, x4, x5)  =  row2colC_in_aggaa(x2, x3)
U6_aggaa(x1, x2, x3, x4, x5, x6, x7)  =  U6_aggaa(x1, x3, x7)
row2colA_in_agaa(x1, x2, x3, x4)  =  row2colA_in_agaa(x2)
U1_agaa(x1, x2, x3, x4, x5, x6, x7)  =  U1_agaa(x1, x3, x7)
nil  =  nil
row2colA_out_agaa(x1, x2, x3, x4)  =  row2colA_out_agaa(x1, x3, x4)
row2colC_out_aggaa(x1, x2, x3, x4, x5)  =  row2colC_out_aggaa(x1, x4, x5)
PB_IN_AGGAAA(x1, x2, x3, x4, x5, x6)  =  PB_IN_AGGAAA(x2, x3)
U3_AGGAAA(x1, x2, x3, x4, x5, x6, x7, x8, x9)  =  U3_AGGAAA(x9)

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

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

PB_IN_AGGAAA(T26, T27) → U3_AGGAAA(row2colC_in_aggaa(T26, T27))
U3_AGGAAA(row2colC_out_aggaa(T28, cons(T119, T120), T118)) → PB_IN_AGGAAA(T119, T120)

The TRS R consists of the following rules:

row2colC_in_aggaa(cons(T57, T59), T60) → U6_aggaa(T57, T59, row2colA_in_agaa(T60))
U6_aggaa(T57, T59, row2colA_out_agaa(T61, X91, X92)) → row2colC_out_aggaa(cons(T57, T61), cons(T59, X91), cons(nil, X92))
row2colA_in_agaa(cons(cons(T82, T84), T85)) → U1_agaa(T82, T84, row2colA_in_agaa(T85))
row2colA_in_agaa(nil) → row2colA_out_agaa(nil, nil, nil)
U1_agaa(T82, T84, row2colA_out_agaa(T86, X139, X140)) → row2colA_out_agaa(cons(T82, T86), cons(T84, X139), cons(nil, X140))

The set Q consists of the following terms:

row2colC_in_aggaa(x0, x1)
U6_aggaa(x0, x1, x2)
row2colA_in_agaa(x0)
U1_agaa(x0, x1, x2)

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

(21) QDPOrderProof (EQUIVALENT transformation)

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

The following pairs can be oriented strictly and are deleted.

U3_AGGAAA(row2colC_out_aggaa(T28, cons(T119, T120), T118)) → PB_IN_AGGAAA(T119, T120)

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

POL(PB_IN_AGGAAA(x₁, x₂)) = x₁ + x₂   
POL(U1_agaa(x₁, x₂, x₃)) = 1 + x₂ + x₃   
POL(U3_AGGAAA(x₁)) = x₁   
POL(U6_aggaa(x₁, x₂, x₃)) = 1 + x₂ + x₃   
POL(cons(x₁, x₂)) = 1 + x₁ + x₂   
POL(nil) = 0   
POL(row2colA_in_agaa(x₁)) = x₁   
POL(row2colA_out_agaa(x₁, x₂, x₃)) = x₂   
POL(row2colC_in_aggaa(x₁, x₂)) = x₁ + x₂   
POL(row2colC_out_aggaa(x₁, x₂, x₃)) = x₂   

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

row2colC_in_aggaa(cons(T57, T59), T60) → U6_aggaa(T57, T59, row2colA_in_agaa(T60))
row2colA_in_agaa(cons(cons(T82, T84), T85)) → U1_agaa(T82, T84, row2colA_in_agaa(T85))
row2colA_in_agaa(nil) → row2colA_out_agaa(nil, nil, nil)
U6_aggaa(T57, T59, row2colA_out_agaa(T61, X91, X92)) → row2colC_out_aggaa(cons(T57, T61), cons(T59, X91), cons(nil, X92))
U1_agaa(T82, T84, row2colA_out_agaa(T86, X139, X140)) → row2colA_out_agaa(cons(T82, T86), cons(T84, X139), cons(nil, X140))
