....words, if there is no SLD refutation for P [ f Qg then there 7 As the conjunction Q contains no quantifiers, vars(Q) are the free variables of Q. 17 should be no CLP refutation for any P [ f c 2Qg either. To ensure this property we use the following definition of a derivation, adapted from [16], in which substitutions are made explicit. This will also enable us to construct resultants in a straightforward manner. Definition 4.1 Let CG = c 2L 1 ; L k a CLP goal and C = A B 1 ; B n a program clause such that k 1 and n 0. Then CG 0 is derived from CG and C in D ....
....the correctness will become much more difficult because one cannot reuse the correctness results of standard partial deduction. In that context, we would like to mention [66] which extends constructive negation for CLP programs, as well as recent work on the transformation of CLP programs [16]. Note, however, that [16] is situated within the unfold fold transformation paradigm and also that no concrete algorithms are presented. Finally, let us mention a recent extension of partial deduction, called conjunctive partial deduction [39, 22] Conjunctive partial deduction handles ....

In other words, if there is no SLD refutation for P [ f Qg then there should be no CLP refutation for any P [ f c 2Qg either.

The research of the second author has been supported by the EC HCM network EUROFOCS under grant n. ERBCHBGCT930496. A preliminary, shorter version of this paper appeared in [11]. 1 Introduction As shown by a number of applications, programs transformation is a powerful methodology for the development and optimization of large programs. In this field, the unfold fold transformation rules were first introduced by Burstall and Darlington [9] for transforming declaratively ....
