Why do levels change?

Recently I posted a problem on brilliant with rating as $Level$ $1$ .
Next day I saw it as level 2 and then afterwards as level 3 .
Why do these rating goes changing ??
Do anybody controls them ?
Or they are determined by number of solvers and viewers ?
Is there any way to keep the level rating constant ?

any help appreciated

Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

It depends.

If your problem was posted at a level and it seems too easy for those who have that level, its rating will go down.

If your problem was posted at a level and it seems too difficult for those who have that level, its rating will go up.

However, moderators can change the rating of a problem if necessary.

And there's no way you can make the rating constant.

I hope I answered your question.

Thanks sir ,

Can you help me with this

is this proof correct

The ratings change base on how the community is performing on the problem. If the problem is solved by many people, then its rating will start to decrease. If the problem fails to be solved by many people, then its rating starts to increase.

This allows us to ensure that even if a problem was given a "wrong" initial level by the creator, it will correct itself over time.

There is no way to keep the level constant.

Similarly, as a problem solver, if you can solve many problems (at your level-ish), then your rating will increase. If you fail to solve problems at your level, then your rating will decrease. This allows you to (over time) find the problems that you should "ideally" be working on.

Sir I also want to ask that

does my rating decrease when someone reports my problem ?

A Former Brilliant Member - 6 years, 3 months ago

Your rating doesn't change when the problem is reported.

Note that if the answer to a problem has been updated and we changed the state from correct to incorrect (or vice versa), then your rating will change.

@Calvin Lin – Sir I also want to ask why names of my problems are changing themselves (mysteriously) ?
Following are the links of those problems whose names have been changed
nested radicals.....
nested radicals.....

There are few more also whose name has been changed.

@A Former Brilliant Member – Moderators are editing titles of some problems if they are in CAPS LOCK or they have such repeated letters, symbols, etc...

Jeremy Bansil - 6 years, 3 months ago

@A Former Brilliant Member – We improve titles as they are the first thing that people notice. Things that we do are:
1. Change "ALL CAPITAL" to "Title Case"
2. Remove unnecessary punctuation like "..............." or "!!!!!!!"
3. Remove claims of "very easy" and "very hard", since that is relative to the individual.

For many of your "Nested radicals ........." problems, their titles have been changed to "Nested Radicals" before we shared them out on FB / email.
