Clauses:

append([], Ys, Ys).

Query: sublist(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:

sublist_in_2: (b,b)

append_in_3: (f,f,b) (f,b,b)

Transforming Prolog into the following Term Rewriting System:

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

   sublist_in_gg(X, Y) -> U2_gg(X, Y, append_in_aag(P, X1, Y))
   append_in_aag([], Ys, Ys) -> append_out_aag([], Ys, Ys)
   append_in_aag(.(X, Xs), Ys, .(X, Zs)) -> U1_aag(X, Xs, Ys, Zs, append_in_aag(Xs, Ys, Zs))
   U1_aag(X, Xs, Ys, Zs, append_out_aag(Xs, Ys, Zs)) -> append_out_aag(.(X, Xs), Ys, .(X, Zs))
   U2_gg(X, Y, append_out_aag(P, X1, Y)) -> U3_gg(X, Y, append_in_agg(X2, X, P))
   append_in_agg([], Ys, Ys) -> append_out_agg([], Ys, Ys)
   append_in_agg(.(X, Xs), Ys, .(X, Zs)) -> U1_agg(X, Xs, Ys, Zs, append_in_agg(Xs, Ys, Zs))
   U1_agg(X, Xs, Ys, Zs, append_out_agg(Xs, Ys, Zs)) -> append_out_agg(.(X, Xs), Ys, .(X, Zs))
   U3_gg(X, Y, append_out_agg(X2, X, P)) -> sublist_out_gg(X, Y)

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

U2_gg(x1, x2, x3)  =  U2_gg(x1, x3)

append_in_aag(x1, x2, x3)  =  append_in_aag(x3)

append_out_aag(x1, x2, x3)  =  append_out_aag(x1, x2)

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

U1_aag(x1, x2, x3, x4, x5)  =  U1_aag(x1, x5)

U3_gg(x1, x2, x3)  =  U3_gg(x3)

append_in_agg(x1, x2, x3)  =  append_in_agg(x2, x3)

append_out_agg(x1, x2, x3)  =  append_out_agg(x1)

U1_agg(x1, x2, x3, x4, x5)  =  U1_agg(x1, x5)

sublist_out_gg(x1, x2)  =  sublist_out_gg
