Codeforces Round 954 (Div. 3)

By 74TrAkToR, history, 4 days ago, translation,


Hello! Codeforces Round 954 (Div. 3) will start at Sunday, June 23, 2024 at
16:35UTC+2. You will be offered 7 problems with expected difficulties to compose
an interesting competition for participants with ratings up to 1600. However,
all of you who wish to take part and have a rating of 1600 or higher, can
register for the round unofficially.

The round will be hosted by rules of educational rounds (extended ICPC). Thus,
solutions will be judged on preliminary tests during the round, and after the
round, it will be a 12-hour phase of open hacks.

You will be given 7 problems and 2 hours and 15 minutes to solve them.

Note that the penalty for the wrong submission in this round is 10 minutes.

Remember that only the trusted participants of the third division will be
included in the official standings table. As it is written by link, this is a
compulsory measure for combating unsporting behavior. To qualify as a trusted
participant of the third division, you must:

 * take part in at least five rated rounds (and solve at least one problem in
   each of them)
 * do not have a point of 1900 or higher in the rating.

Regardless of whether you are a trusted participant of the third division or
not, if your rating is less than 1600, then the round will be rated for you.

The tasks were created and prepared by 74TrAkToR. I would like to thank everyone
who helped me a lot with round preparation.

 * Coordinator Vladosiya for excellent communication and brilliant coordination
   of the round!
 * Testers veleboks, iNNNo, Sk0rlupka, sharkycode, Noobish_Monk, meowcneil,
   Matrosk1n, sumit_kk10, Sonya_2009, FelixArg, KirillKhalin, viteli, zwezdinv,
   EJIC_B_KEDAX, _why_not_, detective...dots, Leeda for high-quality testing and
   valuable advices!
 * MikeMirzayanov for amazing Codeforces and Polygon platforms!

Good luck!

Osijek Competitive Programming Camp, Fall 2024

By adamant, history, 5 days ago,


Hi everyone!

Sponsored by


We are happy to announce that Osijek camp will be returning this Autumn, on
August 31-September 8 2024, right before the ICPC World Finals 2024 on 15-20
September 2024 in Astana, Kazakhstan. The camp is hosted by the School of
Applied Mathematics and Computer Science of the University of Osijek and is
brought to you by the organizing team of adamant and -is-this-fft-.

The camp is inspired by various competitive programming camps that we attended
during our active years in ICPC, and is aimed to help college students prepare
for ICPC regional contests and finals. The camp will consist of 7 ICPC-style
contests and 2 days off.


DETAILS

Participation fee for onsite participants is 150€ per person. It does not
include regular meals, travel or accommodation. Some further details about
location, travel and food options can be found on the website.

If you want to participate, but are unable to come onsite, we offer a reduced
fee of 100€ per person for online participation. It is also possible to reduce
fees individually if you are unable to attend some of the contests. This will be
handled on a case-by-case basis.

We support and empathize with those affected by the ongoing war in Ukraine,
therefore we offer a 100€ discount for affected individuals and teams affiliated
with Ukrainian institutions. In other words, the fees would be 50€ and 0€ per
person for onsite and online participation correspondingly.

The expected starting time for the contests is 10am CET. For online
participants, it is still a preferred starting time, but we will make
accommodations for virtual participation at a later time, whe really necessary.

Most of our contests are originally developed for the camp. A small number of
contests may be based on previous contests that have not been released to the
general public. If you have seen some problems of a contest before, you can't
participate on that day. We will privately contact participants who might be
affected.

After the camp, we will have a silence period during which camp materials will
not be released to the public. We ask participants not to discuss the problems
in public unless they obtained an explicit permission from contest authors.


PARTICIPANTS

If you are interested in participating, please fill the form here.

We ask you to register before August 23 if you want to participate online and
before August 16 if you want to participate onsite.

Also, if your university or organization has a lively ICPC community that may be
interested in attending the camp, and you have some contacts of people in charge
(e.g. coaches) we would highly appreciate if you could share some details in a
direct message to me (adamant) or Tähvend (-is-this-fft-). Thanks!


PROBLEMSETTERS

We'd like to thank and praise the authors of the contests in the camp:

 * conqueror_of_tourist — ICPC 2022 world finalist. Codeforces LGM in Python.
 * tfg — ICPC 2018 and 2019 World Finalist, sqrt decomposition enjoyer and the
   person that optimized the intended complexity of 1508F - Optimal Encoding.
 * Farhod — Codeforces IGM, 2x IOI silver medalist, hates ad hoc problems.
 * Amtek — CERC 2022 and 2023 champion. ICPC 2023 and 2024 finalist.
 * jacynkaa — CERC 2022 champion. ICPC 2021 and 2023 finalist.
 * teapotd — CERC 2019 and 2021 gold medalist. ICPC 2020 and 2022 finalist.
 * wuhudsm — Codeforces Master, maintainer of TheForce community, author of over
   100 competitive programming problems.
 * chromate00 — Problemsetter of 28 tasks on Baekjoon, also known for blogs
   reinventing the wheel several times.

   non-geometry problems.
 * Mustang98, BigBag, Barichek, Denisov, Valera_Grinenko — ICPC World Finals

 * Kevin114514, yaoxi_std, JCY_, Daniel_lele, ducati, Evier., WaReTle, J.Doe,

... And others. We would also like to thank Arpa, two times ICPC World Finalist

proposals. You can find more details about contest rules and technical setup on
the website.

Codeforces Round 952 (Div. 4)

By cry, 3 months ago,



HELLOWO CODEFORCERS :3

sum and I are very delighted, ecstatic, enchanted, euphoric, excited, exultant,
jubilant, overjoyed, and proud to invite you to participate in Codeforces Round
952 (Div. 4), which will start on Tuesday, June 11, 2024 at 16:35UTC+2. There
will be 88 problems, with one split into two subtasks, to be solved in 2.52.5
hours.

As usual, I have to copy and paste the following...

The format of the event will be identical to Div. 3 rounds:

 * 5-8 tasks;
 * ICPC rules with a penalty of 10 minutes for an incorrect submission;
 * 12-hour phase of open hacks after the end of the round (hacks do not give
   additional points)
 * after the end of the open hacking phase, all solutions will be tested on the
   updated set of tests, and the ratings recalculated
 * by default, only "trusted" participants are shown in the results table (but
   the rating will be recalculated for all with initial ratings less than 1400
   or you are an unrated participant/newcomer).

We urge participants whose rating is 1400+ not to register new accounts for the
purpose of narcissism but to take part unofficially. Please do not spoil the
contest for the official participants.

Only trusted participants of the fourth division will be included in the
official standings table. This is a forced measure for combating unsporting
behavior. To qualify as a trusted participant of the fourth division, you must:

 * take part in at least five rated rounds (and solve at least one problem in
   each of them),
 * do not have a point of 1400 or higher in the rating.

Regardless of whether you are a trusted participant of the fourth division or
not, if your rating is less than 1400 (or you are a newcomer/unrated), then the
round will be rated for you.

We want to express overwhelming gratitude to the following individuals for
making the contest possible:

Vladosiya and mesanu for coordinating the contest and reviewing the problems.

Dominater069, omeganot, Phi-001, flamestorm, nskybytskyi, willy108, ScarletS,
mark, yuan-shen, vgoofficial, htetgm, buffering, yash_9a3b, haochenkang, ETL,
natalina, MatthewC3297, and lcsc0 for testing the round.

MikeMirzayanov for the usual.

We suggest reading all of the problems as we have put mucho effort into all of
them. Best of luck, mis amigos!
