Abstract
The automatic synthesis of program methods [Manna & Waldinger, 1980; Kodratoff & Picard, 1983; Franova, 1985],..., etc, allow an automatic generation of programs from their specifications. As interesting as it is, this approach comes up against a usual problem: to define a good specification is very difficult in itself.
In this paper, we propose a method for developing a specification from a program.
We suppose that the program to transform is recursive and that it is given under the form of rewrite rules. Calls to sub-programs are allowed.
This method aims at the construction of the formal specification of the algorithm implemented by the program
The obtained specification expresses the relations between the inputs and outputs of the program.
In the PROLOG case, the program one starts from is a PROLOG program in which the inputs and outputs are singled out (i.e., a “functional” PROLOG program).
The specification one obtains is a PROLOG program in which the relations between variables are the only significant feature (i.e., a “pure” PROLOG program).
Our method uses the algebraic abstract data types [Bidoit, 1982], rewriting systems [Dershowitz, 1984] and Knuth-Bendix completion algorithm [Knuth & Bendix, 1969] and needs for a theorem prover.
