+ Hello. I am an active Competitive-Programmer who has been doing + USACO since 7th grade. You can find more about me on my personal + website. The reason I created + this project was because there currently isn't a concrete system + for evaluating USACO problem difficulties. I remember when I + first started USACO, I had no idea what to train on. Especially + as I reach higher divisions, problems on the same contest can be + vastly different in terms of difficulties. Some were in my + range, some were too hard, and some were too easy. Furthermore, + since I did not know the difficulties beforehand, I often waste + a high-quality problem that isn't in my reach by reading the + editorial. Therefore I hope this project serves as a remedy for + that issue. By quantifying the difficulties and qualities, + people can much easily train on problems that fit for them. +

Frequently Asked Questions

+
+

How should I interpret the numbers?

+
+

+ There are two metrics offered by USACO Rating: difficulty and + quality. Difficulty is a number between 800 - 3500, which + roughly (or at least aims to) corresponds with + CodeForce's rating system. + Quality is on a scale of 1 to 5, with 5 being super high + quality, and 1 being very uninteresting. It is relatively more + subjective, but can act as a nice tool to select good problems, + as well as avoid bad ones. +

+
+

How are the numbers calculated?

+
+

+ We use a democratic voting system where users are allowed to + give their estimates on the difficulty, as well as opinions on + the problem quality. Note that only verified users who we deem + qualified can vote, so there should be minimal trolling, + ensuring a (hopefully) accurate estimate. +

+
+

I want to help contribute! How?

+
+

+ You can help contribute in many ways. The most common way is to + apply for a verified account and voice your opinions on these + problems. You can also directly help improve the project by + creating a pull request on our + GitHub + page. More information can be found on the + Contribute page. +

+
+

I have a suggestion/question/found a bug.

+
+

+ Any feedback is greatly appreciated! You can do so by creating a + new issue on our GitHub issues page. We will review them as fast + as possible. +

+
+

+ Why does this website look similar to Kenkoooo's Atcoder + Problems? +

+
+

+ Haha. Yes, we indeed greatly copied referenced many of + Atcoder Problem's styles. They are under the + MIT License, + so in the spirit of Open Source, we also use MIT License :D. So + yeah, shout-out to Kenkoooo! +

+
+

Can I use the code from this project for other purposes?

+
+

+ Definitely. Under the MIT License, you can reuse the code for + any purpose, sometimes even if they are part of proprietary + softwares. +

+
+

Who made this project?

+
+
