I don't know why but in my country many sites are blocked.
Luckily Codeforces isn't blocked in my country, and I'm looking for OI groups on CF.
If you know such groups please comment it. It will be very helpful.
Update: I can access blocked sites with Tor browser, still it'd be good if I find OI groups on CF because it's a bit slow.
it will be good for me too
Me too!!!
try Kilonova (good,new Romanian OI-style problems website, has english translations for all problems, has a lot of contests and if I am not mistaken has really fast servers)
Blocked. :(
https://www.acmicpc.net/
It's also blocked. :(
Yes but the page can be translated using google translate.
*Korean
is this one also blocked: https://olimpiada.ic.unicamp.br/ ? obs: it is in pt-br
No it's not blocked :). Which OIs does it have?
I think it's for BOI(Brazilian Olympiad In Informatics).
Yep, it's the Brazillian Olympiad in Informatics (OBI in Portuguese) website. All problems there are OBI problems. For those who cannot access the official website or don't know Portuguese, there's this. Just search "OBI" on the search bar and most recent problems should show up.
use V*N
What reason?
I tried free vpns but none of them works. And I can't afford not free ones.
Try psiphon, it works for me when most others don't.
It is very sad all those websites are blocked :(.
I tried psiphon too but it didn't work for me.
Yes it's very sad all those websites are blocked :(.
try this : https://chrome.google.com/webstore/detail/free-vpn-for-chrome-vpn-p/majdfhpaihoncoakbjgbdhglocklcgno
Doesn't work, but I can use Tor.
What about GreenHub?
This?
No, you should visit the offical website and install the software. It has more vertices than web scripts.
Is this official website of GreenHub?
It's blocked. :(
As my profile picture I use ubuntu 23.10.
Yes. And it's not supported ubuntu. What a pity!
Even If it was supported for ubuntu, I couldn't use it. Because its official website is blocked here. :(
Try ProtonVPN
I tried but didn't work. :(
If you haven’t tried already, see if you can access https://qoj.ac/.
It's blocked too. :(
and what kind of website is this ?
It's an online judge hosting a large number of ICPC and OI problems.
There're 1.2 Billion IP Addresses Blocked in Turkmenistan.
Try my country's online judge here
Which country do you live in? It's weird that competitive programming sites would be blocked.
Turkmenistan
What the actual fuck is your government? Try https://f001.backblazeb2.com/file/geph4-dl/geph-releases/windows-stable/4.8.9/geph-windows-setup.exe
Site is blocked and I use Ubuntu.
https://www.luogu.com.cn/ Chinese website, has atcoder statements and some OI problems
It's blocked
I think there are things common in all of them made it be blocked by your country.
idk, for example what?
Did you try usaco.org?
Yes, I use usaco, it's not blocked but I want to try other OI problems too. I also use usaco training. I'm in section 5.3.
Shaazzz
What is Shaazzz? What does it have?
try this
Blocked. :(
Try "SetupVPN" chrome extension, its free and it always works for me
I tried but didin't work. :(
Since VPNs don't seem to work, have you tried Tor or I2P?
Tor and I2P's websites are blocked, and I couldn't install its snap(an error occurs).
After some hard works, I finaly managed to install Tor. It doesn't connect directly but it connects with bridges. :)
Hi, Vietnamese have this group. It has several OI-style contests and problem sets that you may find helpful. The statements, however, are most if not all in Vietnamese so you have to use some translator to read them.
This group is kind of an archive of old problems (we now have a new website for them), but they were practiced by generations of Vietnamese students so I believe there's still a lot of value in them. Some of the problems have editorial, you can PM me on Codeforces when you need them. Good luck!
OK, thx.
Additionally since the group is unused, you can try visit our new website here. If you can access it, you can create an account on it and try some problems.
Unfortunately most of the problems are in Vietnamese, but there are still several English problems as well (for example ICPC national & provincial problems or VNOI Cup problems). Of course if you want to try out other problems as well you can use a translation service such as Google translate.
Unfortunately I can't access it.
try loj.ac hydro.ac poj.org or uoj.ac?
there's a mirror of vjudge,https://vjudge.csgrandeur.cn/
All of them blocked, but I can access with TOR.
I'm using TOR in Ubuntu 23.04. I shared it to my friends but it didn't work for all of them, only works on me. Will I be able to use TOR after installing Ubuntu 23.10 to my pc? I want to install but I'm a bit worried about TOR. I also sent this to frontdesk@torproject.org.
Forunately, Tor connects with bridges.
https://szkopul.edu.pl/ has many POI problems
It's blocked too.
Try cloudflare vpn 1.1.1.1
You can try spanish national olympiad link
I'm going to try all of this
what's the point of blocking those completely CP-related websites?
I also want to know.
I heard they blocked subnet masks. Hope you can find a way around.
If you are lucky enough to be able to visit Virtual Judge, then you can practice all problems of all OJs mentioned in this thread.
So pathetic.
why blocked?
