Минимизация контекстно-свободных грамматик

Abstract

Решается задача преобразования исходной контекстно-свободной грамматики (КС-грамматики) без лишних символов в эквивалентную ей грамматику меньшей сложности. Предлагается способ минимизации КС-грамматики, основанный на введённом отношении на множестве нетерминалов, обладающим свойством эквивалентности. Это отношение разбивает множество нетерминалов на классы эквивалентности, и новая КС-грамматика строится на нетерминалах, являющихся представителями классов эквивалентности. В результате получается КС-грамматика с меньшим количеством нетерминалов и правил.
