18th Tech-CS Programming Contest | |
|
Dear all, The 18th annual Tech-CS Programming Contest was held on Friday, July 7, 2023, with a participation of 18 teams (16 from The Technion). The competition included 12 problems taken from different areas in mathematics and computer science. A correct solution to a problem consisted of a program that solved correctly and efficiently a variety of instances of the problem, covering all kinds of special and degenerate cases, extreme cases in terms of size/complexity of the input, and so on. Here is the top of the final standing: 1st place: Team "Melinda's Angles" - 11 problems * Jonathan Gal * Oren Hecht * Idan Albo ( Competed out of the contest: Team "WinCode"/Haifa U - 10 problems * Guy Shalgi * Yanir Edri * Ofek Shalgi ) 2nd place: Team "NameNotFound" - 9 problems * Zohar Nagel * Eden Yosef * Shirli Mushkatin 3rd place: Team "Eden Hamelech" - 7 problems * Gilad Shmerler * Eitan Bloch * Or Shafran Many thanks are due to all the enthusiastic people without the help of whom this contest could not take place: * The entire CS department's IT team: Gennadi and Konstantin who provided on-site support during the contest, and all other members of the team who helped in setting it up; * Secretariat and staff: Revi Ginossar, Maya Sidis, Ariella Weinstein, and Yaniv Abutbul and his team - for helping us with the complex logistics of this event, and for letting us use the CS library; * External Relations: Noa Mor - for ongoing encouragement and support during the entire semester; * The Competitive Programming course staff: Tomer Cohen (TAIC), Eden Saig, and Snir Green - for delivering a great course and for orchestrating an amazingly smooth competition with absolutely zero problems (except the problems solved by the competing students 8-).

בהצלחה בתחרות | |
|
סטודנטים יקרים בסדנה לתכנות תחרותי, כזכור לכם, הופעתי לפניכם בפגישה הראשונה בקורס, והדגשתי את אופיו השמח של הקורס, ועד כמה לא נעבור בשתיקה על עבירות אתיות כגון העתקת תרגילים או הגשת פתרונות המצויים באינטרנט. להפתעתי, גילינו מספר עבירות מסוג זה, ואנו מטפלים בהן כעת. למי שמעוניין, אסביר באופן פרטי עד כמה שמו הטוב של הטכניון תלוי ברמה האקדמית של הלימודים ובאמינות הציונים שהוא נותן, ולכן כל עבירה אתית תיתקל בתגובה ראויה. במאמר מוסגר: יש לנו כלים מתוחכמים המסוגלים לגלות תרגילים המכילים קוד דומה (אף אם שונו שמות המשתנים והפונקציות 8-) או בעלי פונקציונליות דומה (לדוגמה, רצים 1613 שניות על קלט מסוים) או בעלי בעיות דומות (למשל, עפים בדיוק באותו אופן על קלט שגוי מסוים), ואילו רק דוגמאות מעטות. בכוונתנו לערוך בדיקה ממצה יותר של התרגילים אשר הוגשו בקורס. לכן, אם הגשתם תרגיל משותף, או תרגיל אשר לא אתם פתרתם, עכשיו זה הזמן לומר לנו ולא לאחר שנגלה זאת בעצמנו. ועכשיו לחלק היותר שמח. ביום ששי הקרוב תיערך תחרות הסיום של הקורס. מובן מאליו שאסור לצוותים שונים לשתף פעולה בשום דרך, לא לגשת לאינטרנט, ולא להשתמש בטלפון. אני מקווה שתיהנו מאד מן התחרות, ושהצוות הטוב ביותר ינצח ויזכה בפרס המובטח: השתתפות בתחרות ICPC/SWERC הנערכת בדרום-מערב אירופה זה שנים רבות. בהצלחה לכולם, גיל |

Announcements | |
|
Dear students, Upcoming class: Due to the department night next week, the class will be ended at 18:20, and will be only a competition (including all the course material). It is recommended that you bring the 25 pages cheat sheet with you, but not mandatory. In the past years the subject in the class was advanced math, it will not be so this year, if you want you can find the tutorial on this subject here: https://panoptotech.cloud.panopto.eu/Panopto/Pages/Viewer.aspx?id=c81f77b3-f7c6-4380-9810-ad4d015b7bfa It is not a mandatory watch, and you do not need any of the material taught there in the competitions. Practice Competitions: We uploaded 2 practice competitions: 1. Last year practice competition. 2. Last year final competition. If you plan to try them out, we recommend to try as a simulation (as a team and to time it). Last year the first places solved 5 questions in the final competition. We also uploaded the solution presentation for the final competition (of last year...). Regards, Course Staff |

Question D in Class Competition #4 | |
|
Dear students, We wanted to address the edge case in question D in the last competition that failed the attempts to pass it. The reason why finding directly the values of a and b doesn't work is since a and b can be complex numbers. For example, if a+b=0, a*b=1, then a=i, b=-i will satisfy these equations.

HW0 | |
|
Dear students, We added questions C, D to HW0. They are the same as questions A, B. We added them since UVA judging system did some issues in the past days (although it seems to work fine now), so you can submit the code for question A also under question C, and the code for question B under question D (if the submit button for questions A, B don't work).

Starting Workshop in Competitive Programming! | |
|
Dear students, Our first lesson will take place on Tuesday (21/03/2023) at 16:30 in Taub 7. In this lesson we will introduce competitive programming and the workshop, solve some questions together, and have a first warm-up competition in singles. What do you need to to before the class: - Please open an account on https://vjudge.net/ . Try to choose an indicative username (or set a nickname), as it will show on the scoreboard in class. - Fill the following form: https://forms.gle/XN7bMEweGh6kBHAg9 - We will add you to the course group, you will be able to see it under the "Group" section in vjudge. - To see that you know how to work with vjudge, you can join the competition 'Introduction contest' inside the group and solve the (easy) problem there. Note that attending this lesson is mandatory for taking the workshop. If you have a problem with attending, please let us know in advance. May we all have a pleasant and fruitful semester!
