Update 1.0 : The app is now live here.

Hello Codeforces,

So, I got some requests to predict the future ratings from my fellow coders and I simply didn't ignore it. I have worked a way through which a user can get their future ratings predicted by a piece of code. It was inspired by stefdasca's blog but since I am a bit weak in geometry and graphs so I decided to write a code for it (ignoring the fact that I am weak in coding too).

I have tested it rigourously for like 2-3 times and it did work as the results were satisfactory.

For Eg: The case of 1-gon's profile:

How to get your future ratings:

Using Web hosted page
Using C++ code

I would encourage some participation from you guys and post in the comments what results you get. Also, if you want me to do a prediction myself I will try my best to be as random as I can.

If the code challenges you to solve a problem don't just run away. Happy coding.


Future endeavour:

P.S. This work is just for fun so don't ask me any proof for it. You can just trust the ratings as it is just a work of statistics and random function with a little bit of K-Means algorithm.

[Some self promotion: Follow me on github and star this repo if you find it helpful and all of the code related to this blog is in this separate repository.]

Why does the prediction depend on the choice of a lucky number?I tried multiple lucky numbers and it showed different results

    That's why it's called "lucky" number

    Actually the result is generated through randomisation and KMeansLike algorithm so you will get different results every time. Lucky number is just a random number to decide the number of intermediate predicted ratings to be generated. All of those results will be in a specific range which corresponds to the predicted rating range and predicted rating is the most probable one of them.

Your program just give me a bunch of string problems for practice!

I like it!

    Here you go

    A rainboy detection mechanism has been employed.

It predicted my future rating to be 2214. Would love that tbh, haven't crossed 2200 for a while.

Amazing work out there! I'm looking forward for future developments.

P.S: it looks like I should take contests again since my predicted rating is bigger than my current rating :D

This is what it predicted for me:

And this is the problem I got told to solve.

I have also created a similar service! Go to random.org, put "500" under Min, "4000" under Max and press the "generate" button. This will be my prediction of your rating after 5 years.

This actually works :} It predicted that within few contests, I'll be a pupil and my rating will be 1248 or something (Don't remember exactly) Now I am a pupil :}
