Program Constructionby Verifying Specification

A program construction method based on Gamma language is proposed. The problemto be solved is specified by first-order predicate logic and a semantic verification program isconstructed directly from the specification. Ways for improving efficiency of the program arealso studied. The method differs from the one proposed by Manna and Waldinger, where aprogram is extracted from the proof of the existence of an object meeting the given specification.On the other hand, it also differs from the classical one used…
