So let's say we have our black box fsmsim.

People would normally write out these almost Tic Tac Toe like board.

Of course they will.

So that's the function.

And it's like espresso coffee, you know, you take the essence of the coffee.

That's hard to say.

Here I have on the screen my country bubbles.

So this is, I'm representing a.

Resources are things like this pile of nuts and bolts that are used somewhere in a plan.

You're kind of like constantly going until you figure out which one it is.

All right. You did all your token definitions. We found them all.

Well, if you haven't noticed we've been using a lot of regular expressions in building our web browser.

First, actions are represented as objects in first order logic, normally by functions.

If we sculpt this, this has two reference points.

How is it would be more accurate.

It's the power of an image.

Because they're not willing to be at risk.

In printing this out should now invoke this repr method, which would automatically provide a nice string representation of our time.

A regular expression. Matching lines will be bookmarked.

44 doesn't match, because it doesn't start with a through z. d4 looks very good.

We can write down all the laws of physics we know in one line.

They both are essentially representing the same xy relationship.

Now I have a field that memorizes for all these states over here the action that it took to get in there, but I don't have this wonderful representation as I have over here.

When we submit our form now what we should see is an error message and our form field should still have our values in it.

So that's what's left there.

Doesn't matter if we turn the whole of space around by some angle, it doesn't leave the doesn't change the phenomenon of electricity or magnetism.

How do I say this?

This shows which level you are at.

I use a simpler version, which is basically a bunch of characters, an sign, a bunch of characters, a period, and then a bunch of characters.

This one is a little bit more complicated here's are rule for STRlNG(token)s.

So, our dictionary for describing cancer is very, very poor.

What we're going to do is we're going to feed in the first character into our regular expression simulator.

For computing it's almost always the case that we want to use a digital abstraction where everything only represents 1 of 2 things.

like hyphens or punctuation.

Password is a similar thing, basically any characters between the length 3 and 20.

It's going to turn out that balanced parentheses are one of the first things we've seen that are too complicated to be captured accurately by our old, dearest friend, the regular expressions.

Clicking this will open a regular expression dialog where you can graphically create regular expressions.

What this one says here is it says if the URL is of the form _history plus this regular expression basically _history anything match the history page.

A maimed monument and a maimed Mall for a maimed collection.

If we had divided the world up not into individual world states, but into variables describing that state, then this whole belief state could be represented just by

And that notation is Sigma notation.

We want to do even more with regular expressions, such as matching a word or a number.

So the instantaneous slope is the derivative.

And the notation we use for derivative is dy over dx.

The comparison here is simple.
