....for in the absence of some computational paradigm and we thought it would help, at the start, to anchor such a system in logic programming inspired reductions. Work by the RUBY group at Oxford on hardware [BroHut, JonShe] and on program synthesis via relations by Bird and de Moor[Algebra] Maddux[Maddux, RelSem], Naumann [Naumann] and Backhouse [Backh] to name a few of the many researchers in this field, suggests that the relational paradigm can provide significant computational insights at almost every level of the field. Exploration via relations of possible connections between program synthesis ....

For an introduction to the theory of relation algebras we refer to J onsson [30, 31] or Maddux [41]. It soon turned out that the RA axioms do not exhaustively generate all valid principles governing binary relations, in other words: RA is only an approximation of RRA. In fact, RRA is not axiomatizable by a finite (purely equational) axiomatization, as was shown by Monk (cf. 49] This negative ....
