On Tree Substitution Grammars,n, nor intersection, nor complements. Indeed unions of tree substitution languages even generate an infinite hierarchy. However, all finite and all co-finite tree languages are tree substitution languages.文字 发表于 2025-3-27 02:53:37

A parsing expression grammar (PEG) is an unambiguous grammar such that the choice operator selects the first matching in PEG while it can be ambiguous in a context-free grammar. PEGs are also closely related to top-down parsing languages. We consider two problems on parsinRinne-Test 发表于 2025-3-28 01:59:51
