A number of people have posted recently about the availability of hard problems on Brilliant. I’d like to share our related planned updates and the philosophy behind them.
Some time ago on Brilliant, when the community was much smaller, members would get approximately 4 new problems each week at their level in each of Algebra, Number Theory, and Combinatorics. Calvin and Arron wrote many of these problems, and also published some of the problems that you submitted to us.
As the weeks passed and the community grew, we found that the majority of members wanted more than 3 subjects, and more than 4 problems per week per subject. We tried experimentally to introduce new subjects like Physics, but could not keep up with the work. The only way for our small team to support that kind of growth was to become moderators of a community that shares its own problems, and eventually appoint community moderators to help out.
We are confident that as the community continues to grow and moderation improves, that both the quantity and quality of problems on Brilliant, as well as the solution discussions, will be better than they ever were when two people on our staff released a handful of problems each week. In the meanwhile, some weeks we have fewer great hard problems, and some weeks we have more. Overall, the number of high-quality hard problems introduced to Brilliant each week is similar to before, but they are distributed somewhat randomly between many more subjects, based on what members choose to submit that week. We expect the number of hard problems to continue to grow over time, as more members become active in the community.
If you miss having small sets of carefully chosen problems, then check out some of the sets that Calvin and Arron have made. They'll release these periodically, and other members are starting to make their own too. Perhaps someone from the community will compile a list of good sets makers soon :)
In addition to moderation improvements, other updates that are happening in the next couple of months that should help ease our way to a better and more endlessly challenging Brilliant are:
- We will be releasing the archives of past Brilliant problems, which have been unavailable since we launched the feed and are currently not accessible via search
- We will allow members to post problems to any topic, rather than being limited to the few “official” topics on Brilliant
- We will continue to make changes to make it easier for you to find the problems you’re most interested in
