Chapter 6 Properties of Context-free Languages Lemma 1 (The pumping lemma for context-free languages). Let L be any infinite CFL. Then there exists a constant n, depending on L, such that if z is in L and |z| n, then we can write z = uvwxy such that 6.1 Pumping Lemma for CFL'...
Section 6.1 establishes an important result, called the pumping lemma for context-free languages, which represents a useful tool for demonstrating that some languages are not context-free. Section 6.2 examines closure properties for the family of context-free languages. Finally, Section 6.3 studies ...
It is in- tuitively obvious that grammars in this form can describe languages which are closed under the operation of taking arbitrary permutations of strings in the language. (Such languages will be called symmetric.) Ordinary context- free grammars, on the other hand, "seem to require that ...

'Maintown' in this paper is similar to that in the work of Brice Heath; 'Ntsha Tsela' is introduced as a uniquely (South) African context; and 'Roadville', the point of greatest integration and change in education, provides a site for future deeper analysis. 展开 ...

In the context of the LangChain framework, this error is likely occurring because the 'query' property is not being correctly set in the ConversationalRetrievalQAChain. In the context shared, the ConversationalRetrievalQAChain class uses 'question' and 'chat_history' as input keys. If you're ...
