"I need to go back to elementary school and learn me some grammars. But... I'LL BE BACK."
they is works with good grammars. I don't know, that question is too broad.
There are four main types of grammars in formal language theory, classified by the Chomsky hierarchy: Type 0 (recursively enumerable grammars), Type 1 (context-sensitive grammars), Type 2 (context-free grammars), and Type 3 (regular grammars). Each type has different generative power and constraints, with Type 3 being the simplest and Type 0 being the most complex. These grammars are used to define and analyze the syntax of programming languages and natural languages.
A context-free grammar can generate languages that regular grammars cannot, as it allows for the use of non-terminal symbols in productions. Regular grammars, on the other hand, are less powerful and can only generate regular languages, which are a subset of context-free languages. Context-free grammars are more expressive and have more flexibility in rule definitions compared to regular grammars.
• CFG’s can generate some regular languages.• CFG’s can generate some nonregular languages.
That is not a question. Please ask a question.
you can ask him a question on twitter and see if he replies or send him some fan mail?
Regular expressions and context-free grammars are both formal languages used in computer science to describe patterns in strings. Regular expressions are simpler and more limited in their expressive power, while context-free grammars are more complex and can describe a wider range of patterns. Regular expressions can be converted into context-free grammars, but not all context-free grammars can be represented by regular expressions.
In general, finite state machines can model regular grammars. Deterministic finite automata can represent deterministic context-free grammars. Non-deterministic finite automata can represent context-free grammars.
what are some good safety question in oilfield or pipeline that i can ask ?
