For those of you attending Moed B:
As mentioned in a previous message, the exam will be 3 hours.
Also, I'm afraid I will not be physically around, but I have arranged replacements, and I will do my best to be available online in real time.

Moed B - 3 hours!
Just to give you an early heads-up:
Moed B (18.9.22) will be ***3 hours*** long.
The format will be similar to Moed A.

Exam A Grades + Appeal policy
I've marked the exam and published the (factored) grades.
I will send the notebooks for scanning tomorrow, you should get them within a day or two.
Notes on the exam and the grade factor:
It was very evident from the exam that there was not enough time, and that the level may have been too hard for the short time available.
To counter these difficulties, I implemented the following factor: let X be the sum of points you got, then the factored grade is X+25 (capped at 100).
The final grade was computed as written in the Syllabus.
I hope the grades alleviate some of the frustration I know most of you felt after the exam.
Like I said, this was a "calibration test" -- a necessary evil in a new course. Future generations will thank you.
For the appeal policy: once you get the exam scan, read it carefully as well as the solution. If you want to appeal, email me within a week with your appeal.

Exam structure, instructions, suggestions, and other useless information
Some info on the exam, which in my opinion is pretty useless, but if you find it comforting - great.
Material: everything we covered. In the notes: up to and including Section 13, excluding Theorem 13.2.
What you need to memorize:
- The different acceptance conditions for automata, including their acronyms (DPW, NRW, NBW, etc.)
- The syntax and semantics of LTL, S1S, and games.
There is not much else to memorize. I will assume you know and understand the various constructions we've seen, but this is more about understanding than memorizing.
- The exam will be *2 hours* long.
- It will consist of 4 questions. Some answers require proofs, but some will be very short (so there is not too much writing to do).
- The questions will resemble the homework in the sense that they will be questions about the material...
How to prepare:
- I don't know.
- Go over the material and the homework and think whether you understand it.
- If you have time, try to play around with definitions and ideas and ask yourself what would happen if this or that changes.
As usual, if you want to meet and ask questions, either come to my reception hour or email me to schedule another time. Or Piazza.

Formal verification job advertisement
Avital Steinitz, a former colleague of mine, works at a company that does formal verification and automata related stuff.
He asked me to pass along a recruitment ad. See below the job description, in case you're interested.
Disclaimer: I am not affiliated with this company or this job in any way. Moreover, I have no information about what they actually do.
If you're interested and want to talk to Avital before applying, let me know and I'll connect you.
Lightlytics is a SaaS platform that helps companies code and deploy configurations faster and safer from plan to cloud. The platform creates a real-time simulated model, or “Cloud Twin”, of the production environments across the entire cloud-native stack that simulates all configuration changes. Developers and engineers can then use this model to automatically predict, preempt, and prevent critical business disruptions caused by infrastructure changes. DevOps teams and Ops teams depend on Lightlytics to increase confidence, reduce costs, and prevent downtime, data loss, and deployment delays. Gain confidence in every configuration at lightlytics.com.
We're growing and things are great. But there's just one thing missing: You!
We are looking for an experienced Algo Developer to join our Core R&D Group. Be part of our software architecture team, responsible for architecting, seeding, leading, and driving cloud-focused product features. You will join the fast paced, highly technical and savvy group in charge of building Lightlytics’s core and algorithms, while working with cutting edge technologies.

COVID in class
I've been informed that one of the attendants in today's class was tested positive for COVID (after class).
Naturally, automata-oriented people have stronger immune system than "normies", but still - you may want to get tested.
Good health to all.

Free access to FLoC! (in return for volunteering)
tl;dr: if you want to volunteer in FLoC, you can get free access:
As I mentioned a couple of times, during the summer we will host a multi-conference event called FLoC:
If you're interested in automata/logic/games/verification (which you obviously are), there will be interesting talks there, by the very best researchers in the field.
Registration is generally quite expensive, but if you volunteer, you get free access (and a T-shirt!)
This involves helping with registration, directions, moving microphones around, etc.
You can register in the link above if you're interested.

I recommend solving it before the lecture of 8.5, simply because that lecture won't be related to the exercise, so it's better if you don't have the exercise deadline looming.

Welcome to Automata, Logic and Games (ALG)!
ALG will start on Sunday, but we can all start getting excited today!
Please read the syllabus and FAQ on the course website, so you have a rough idea what to expect.
We'll discuss the administrative stuff in class. In the meantime, here's a link to Piazza forum for the course, where you can ask questions, discuss the material, etc.
Looking forward to seeing you all,
