\(\Sigma^+\)-programs and their semantics. (Russian) Zbl 0696.03014
A lot of notions are included concerning logical aspects of computer science, as: \(\Sigma^+\)-formulas, \(\Sigma^+\)-definitions, \(\Sigma^+\)-schemes, \(\Sigma^+\)-programs (the symbol “+” marks the positivity of atomic formulas), standard strategy (as a deductive relation, recursively defined), and translations of parametrical logic programs into \(\Sigma^+\)-programs.
Among the results of the paper, there are two theorems asserting, respectively: correctness of the mentioned translation scheme of logic programs into \(\Sigma^+\)-programs; correctness and completeness of the standard strategy relatively to the semantics of \(\Sigma^+\)-programs.
Some remarks concerning the direction of future investigations in the matter are also included.
