The GAMMA Model and its Discipline of Programming
Jean-Pierre Banâtre, Daniel Le Métayer
Science of Computer Programming 15(1), pages 55–77
November 1990
We present a new formalism called GAMMA in which programs are described as multiset transformers. We show the relevance of this formalism with respect to program development by proposing a systematic program derivation method and illustrating it with several nontrivial problems (sorting, shortest path, longest upsequence).
