Okay. Is there a textbook? Yes, there is a textbook. It's Russell and Norvig's Artificial Intelligence, a modern approach. For the last about 20 years, that's the most used textbook. It's very good.

In the US, it already has a fourth edition. In Germany, you can buy the third edition.

The German version of the textbook is still based on edition two.

I like the third edition much better than edition two, and so my course is based on the third edition.

Is the fourth edition worth the extra buck? I don't know. I've requested an examination copy of the book, but they're not giving me one because it's the US edition and they would have to pay.

They would have to pay a tariff on that. And they're not willing to do that. So I can get my hands on this in April when it becomes available.

Is it a hard requirement? No. Everything you need will be in the course notes, which you can find in this place.

If you go to quark.info, that's the web server of my research group, teaching, you can imagine what that means. AI, you can imagine what that means.

We have the course notes there. They're heavily marked up and cover everything. I will try to publish the course notes.

Always. I can also promise that I will sometimes forget, send me an email or so, then I'll directly do that.

We sometimes find errors. I mostly when I look at the slides again, or you when you look at the slides, then just send me an email.

I'll correct all errors as we go along and the slides get better and better.

Okay, so you don't need the textbook, but it's a good book.

I've been told that at least the third edition, you can find PDFs of in the usual places.

So it's the Russell and Norvig. Some of the things it covers less than my course, some of the things that covers a little bit more.

So we'll. So it's worth it's worth doing. I will clarify how to join the tutorials and so on, on the FSI forum.

Everything will be clarified there.

Right. The forum is this one.

I have already given kind of the the setup, most of the stuff that's on these slides I've discussed there for the second semester.

There's also a forum that is the second one here.

Right. Course videos.

So, the course has been recorded in recent years.

Students have actually made heavy use of that there are recorded courses in English and in German.

And this. Oh, there's an error. I already found one. See, it's not course 1890 but 1690.

But you can search for it anyway. So, what I've already done is for this semester, we've recut all the 2018 English videos

into kind of bite size things there between five and 30 minutes long, because actually

watching a course video of one and a half hours can be very tiring.

So, we're kind of semantically cutting them as video course nuggets. And you can find them in this URL only that is 1690.

Let me maybe briefly show you this.

Let me show the screen again. Where is my Firefox.

Can you see this.

I don't really see it.

Right. So, we've basically put all the clips into chapters.

Chapter zero is all the recaps. Chapter one is what we're doing today. And the you'll see clips here that basically give you short versions that are manageable.

And I'll use the course forum to actually show you, tell you what to watch.

Okay. Back to the slides.

Oh, my nicely arranged chat has gone away. There we go.

Hey, we've reached 200 participants.

Okay.

Right. Are we allowed to build a group of four? No.

Up to three. Right.

Okay. Any questions that I've missed.

Good.

Right.

How to use the lecture resources, the

very nice guide by the by the by the media center.

If you haven't seen it, look at it. This, by the way, is not Russell and Norvig, but somebody at the media center.

I would like to recommend that.

Okay.

The AI course is getting more and more popular.
