With regard to the inferred argument filtering the predicates were used in the following modes: delete_in_3: (b,b,f) delmin_in_3: (b,f,f) less_in_2: (b,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: delete_in_gga(X, tree(X, void, Right), Right) -> delete_out_gga(X, tree(X, void, Right), Right) delete_in_gga(X, tree(X, Left, void), Left) -> delete_out_gga(X, tree(X, Left, void), Left) delete_in_gga(X, tree(X, Left, Right), tree(Y, Left, Right1)) -> U1_gga(X, Left, Right, Y, Right1, delmin_in_gaa(Right, Y, Right1)) delmin_in_gaa(tree(Y, void, Right), Y, Right) -> delmin_out_gaa(tree(Y, void, Right), Y, Right) delmin_in_gaa(tree(X, Left, X1), Y, tree(X, Left1, X2)) -> U6_gaa(X, Left, X1, Y, Left1, X2, delmin_in_gaa(Left, Y, Left1)) U6_gaa(X, Left, X1, Y, Left1, X2, delmin_out_gaa(Left, Y, Left1)) -> delmin_out_gaa(tree(X, Left, X1), Y, tree(X, Left1, X2)) U1_gga(X, Left, Right, Y, Right1, delmin_out_gaa(Right, Y, Right1)) -> delete_out_gga(X, tree(X, Left, Right), tree(Y, Left, Right1)) delete_in_gga(X, tree(Y, Left, Right), tree(Y, Left1, Right)) -> U2_gga(X, Y, Left, Right, Left1, less_in_gg(X, Y)) less_in_gg(0, s(X3)) -> less_out_gg(0, s(X3)) less_in_gg(s(X), s(Y)) -> U7_gg(X, Y, less_in_gg(X, Y)) U7_gg(X, Y, less_out_gg(X, Y)) -> less_out_gg(s(X), s(Y)) U2_gga(X, Y, Left, Right, Left1, less_out_gg(X, Y)) -> U3_gga(X, Y, Left, Right, Left1, delete_in_gga(X, Left, Left1)) delete_in_gga(X, tree(Y, Left, Right), tree(Y, Left, Right1)) -> U4_gga(X, Y, Left, Right, Right1, less_in_gg(Y, X)) U4_gga(X, Y, Left, Right, Right1, less_out_gg(Y, X)) -> U5_gga(X, Y, Left, Right, Right1, delete_in_gga(X, Right, Right1)) U5_gga(X, Y, Left, Right, Right1, delete_out_gga(X, Right, Right1)) -> delete_out_gga(X, tree(Y, Left, Right), tree(Y, Left, Right1)) U3_gga(X, Y, Left, Right, Left1, delete_out_gga(X, Left, Left1)) -> delete_out_gga(X, tree(Y, Left, Right), tree(Y, Left1, Right)) The argument filtering Pi contains the following mapping: delete_in_gga(x1, x2, x3) = delete_in_gga(x1, x2) tree(x1, x2, x3) = tree(x1, x2, x3) void = void delete_out_gga(x1, x2, x3) = delete_out_gga popout
