(3) TriplesToPiDPProof (SOUND transformation)

We use the technique of [DT09]. With regard to the inferred argument filtering the predicates were used in the following modes:
revB_in: (b,f)
revA_in: (b,b,b,f)

The argument filtering Pi contains the following mapping:
.(x1, x2) = .(x1, x2)
revA_in_ggga(x1, x2, x3, x4) = revA_in_ggga(x1, x2, x3)
[] = []
REVB_IN_GA(x1, x2) = REVB_IN_GA(x1)
U2_GA(x1, x2, x3, x4, x5, x6, x7, x8, x9, x10, x11) = U2_GA(x1, x2, x3, x4, x5, x6, x7, x8, x9, x11)
REVA_IN_GGGA(x1, x2, x3, x4) = REVA_IN_GGGA(x1, x2, x3)
U1_GGGA(x1, x2, x3, x4, x5, x6) = U1_GGGA(x1, x2, x3, x4, x6)

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

(9) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

REVA_IN_GGGA(.(X1, X2), X3, X4) → REVA_IN_GGGA(X2, X1, .(X3, X4))
The graph contains the following edges 1 > 1, 1 > 2
