Answers to homework questions are due two weeks after we post the exercise. Answer each question on a separate page.
While we encourage working together on the exercises as well as using any written sources that you find, you must write your solution completely alone. In every exercise please indicate the name of all those that you have worked with as well as all sources that you have used.
As usual, submit comments to this page in order to sign up for grading homework exercises. This can be done in pairs. Please submit the grades in this Excel sheet.

אופס, לאחר קריאה מדוקדקת הבנתי שאם כבר כתבתי סקרייב (אבל לא נרשמתי לבדיקת תרגיל) אז אני לא צריכה לפרסם פתרון.
אז אני מסירה את הבקשה הקודמת שלי.
תודה וסליחה 🙂

Hi,
I would like to submit a solution for question 5 in Ex1
thanks
Hi i would like to post a solution to ex1 q4. or any of ex1 question for that matter.
Hi,
In ex2 q1, the graph is directed, right? I mean, it is possible for player 1 to depend on player 2 while player 2 does not depend on player 1.
This means that we’re actually dealing with a DAG… ?
Thanks,
Dina
You can assume that it is undirected. I.e. we put an undirected edge between two vertices if one of them depends on the other.
now i’m a bit confused. do we have the knowledge of who depends on whom? if so, why not treat it as a directed one? i’m asking becasue i have a solution in mind which assumes that the graph is directed…
Your solution needs to work even if the dependence along an edge is in both directions. It’s not really more difficult, just a bit more confusing.
i’d like to check q 2 in ex 4 with jonathan weill
tnx
hi,
i’d like to write a school solution to question 1 in ex3, when it comes out.

Hi, I would like to submit a school solution to Q1 or Q2 in ex3
I’d like to write the school solution for the 3rd question in ex3.
A message to David Hananel & Gal Ben Ishay:
We’re currenly supposed to check q.4 in Ex2, which was moved to the next exercise. We need you to swap with us and take this question instead of yours (5), because we are unable to check a question in the next exercise. Noam has already approved of this swap, and told us to let you guys know…
Contact us if you see this.
(ido.frizler@gmail.com, liat.hayun@gmail.com)
Sorry for the trouble,
Ido and Liat.
Hi,
I would like to write a school solution to any question that is still available.

Thanks,
Yulia.

hi,
you skipped me for some reason… (I’ve written a message in 7th and 10th of the month.)

Thanks
In the end I’m doing a scribe, so I’m withdrawing my request to write a solution
great!

Just a reminder (already posted this on the 7th): I would like to submit a solution to the first question available.
If (and only if) it needed, I will write solution to ex3 – q3.
(I don’t write lecture notes).
Thnks
I would be glad to write a solution for any question in ex4.
I want to check question 3 in ex4.
Hi,
I would like to cancel the registration to the course and get my money back.
I would like to write a solution for any question possible.
This is the third time I ask to write a solution (not including the mail), please let me know if it is possible or what to do if it is not.
thanks,
Yulia.
Yulia, I hope Noam’s comments in the beginning of the last class explained why we were not able to assign any more chores.. and that the situation is clear now. Let me know otherwise.
Hi,
Where is the damn neighborhood that was promised to us in the beginning of the semester? it was said very clearly that it will be AT THE LEAST a market, and that it might eventually become a carnival.
