Finite State Machines, adding a lexer that follows them automatically,

Some of them are political. Many of them are physical.

You might think, Boy, is there a context expensive grammar out there? What's the opposite of free?

The brain is recording all information and driving all change in temporal context.

These grammars that we've been introducing describe something new context free languages.

It relates grammars to parsing, which is one of the concepts in this class.

I took care of in that HlV clinic.

Units 3 and 4 were relatively abstract to some degree, intentionally so.

Officially, they're characterizing that it was a coronary brought on by systemic shock.

It depends on the context.

This branch of the family is all about representation.

I am just gonna pause for a moment to let you think about that.

So in lecture, we spent a lot of time learning about context free grammars and languages.

like HTML or SQL, the language of database queries.

But that's an example of an application that also uses this sort of linguistic analysis perhaps a little less related to context free grammars but still in the same vein.

Shape shifting Dinosaurs

Well, because, sentences are more interesting.

All of that is going to matter for figuring out the true interpretations of programs.

The set of languages that can be described by re write rules or grammers like this are called context free languages.

There are real concerns there.

I took the Copenhagen subway map and

Here I've written down four claims.

Y has the value of 2.

But if right above it I've written X 0, then we'd get a different answer.

It handles LL. It handles LR. It handles LALR.

That line above it is the context.

And understand its interactions with the entire Earth.

You know, thousands of scientists have been working on understanding all of these man made causes and the natural causes.

Lots of risk factors, but there is a genetic predisposition to prostate cancer.

So those are all natural causes of climate change.

This is called being lazy, and it's a phenomenal virtue when you're writing programs.

Actually, they're both just concise notations for specifying possibly infinite sets of strings.

... the misspelled word shown in context...

It turns out that interprocedural data flow analysis is the same problem as, in a theoretical sense, context free language reachability, which is the same problem as could I generate a string in a context free grammar.

All right. So, it's another one of these puzzle like questions.

They're the actual input that we're trying to match.

Sometimes this statement is true, and sometimes it's not.

A context free grammar can capture the language a N and b N, where N is the same.

That's much more important than knowing the particular syntax for any language.

The concept conjures of thoughts of our species, our planet and our civilization.

And you correct me if I'm wrong.

These are just the ESPN SportsCenter version of the game.

These days I think your time, the human's time, is more important than the computers.

That's a good point, Peter, and the answer is yes.

You may not have the money, or the Supreme Court, but that is not the defining factor.
