Query: transpose(g,g)
----------------------------------------

(1) PrologToPiTRSProof (SOUND)
We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes:

transpose_in_2: (b,b)

transpose_aux_in_3: (b,b,b)

row2col_in_4: (b,b,f,f)

Transforming Prolog into the following Term Rewriting System:

Pi-finite rewrite system:
The TRS R consists of the following rules:

   transpose_in_gg(A, B) -> U1_gg(A, B, transpose_aux_in_ggg(A, [], B))
   transpose_aux_in_ggg(.(R, Rs), X1, .(C, Cs)) -> U2_ggg(R, Rs, X1, C, Cs, row2col_in_ggaa(R, .(C, Cs), Cols1, Accm))
   row2col_in_ggaa(.(X, Xs), .(.(X, Ys), Cols), .(Ys, Cols1), .([], As)) -> U4_ggaa(X, Xs, Ys, Cols, Cols1, As, row2col_in_ggaa(Xs, Cols, Cols1, As))
   row2col_in_ggaa([], [], [], []) -> row2col_out_ggaa([], [], [], [])
   U4_ggaa(X, Xs, Ys, Cols, Cols1, As, row2col_out_ggaa(Xs, Cols, Cols1, As)) -> row2col_out_ggaa(.(X, Xs), .(.(X, Ys), Cols), .(Ys, Cols1), .([], As))
   U2_ggg(R, Rs, X1, C, Cs, row2col_out_ggaa(R, .(C, Cs), Cols1, Accm)) -> U3_ggg(R, Rs, X1, C, Cs, transpose_aux_in_ggg(Rs, Accm, Cols1))
   transpose_aux_in_ggg([], X, X) -> transpose_aux_out_ggg([], X, X)
   U3_ggg(R, Rs, X1, C, Cs, transpose_aux_out_ggg(Rs, Accm, Cols1)) -> transpose_aux_out_ggg(.(R, Rs), X1, .(C, Cs))
   U1_gg(A, B, transpose_aux_out_ggg(A, [], B)) -> transpose_out_gg(A, B)

The argument filtering Pi contains the following mapping:
transpose_in_gg(x1, x2)  =  transpose_in_gg(x1, x2)

U1_gg(x1, x2, x3)  =  U1_gg(x3)

transpose_aux_in_ggg(x1, x2, x3)  =  transpose_aux_in_ggg(x1, x2, x3)

.(x1, x2)  =  .(x1, x2)

U2_ggg(x1, x2, x3, x4, x5, x6)  =  U2_ggg(x2, x6)

row2col_in_ggaa(x1, x2, x3, x4)  =  row2col_in_ggaa(x1, x2)

U4_ggaa(x1, x2, x3, x4, x5, x6, x7)  =  U4_ggaa(x3, x7)

[]  =  []

row2col_out_ggaa(x1, x2, x3, x4)  =  row2col_out_ggaa(x3, x4)

U3_ggg(x1, x2, x3, x4, x5, x6)  =  U3_ggg(x6)

transpose_aux_out_ggg(x1, x2, x3)  =  transpose_aux_out_ggg

transpose_out_gg(x1, x2)  =  transpose_out_gg
