Это маленький примерчик, увидела в книжке -- добавила, он не особо показателен. Распознаем шпильки (hairpin) с длиной спирали 3 и последовательностью в петле gaaa и gcaa. В языке, порождаемым этой грамматикой, строки всегда одной длины (10 символов).

Добавлен парсер для грамматики, задающий язык { [^n (^m ]^n )^m }. Она применима в биоинформатике для поиска pseudoknots. |
