cpdojo's blog

Hi CF community,

Recently I launched CPDojo problem recommendation system which recommends problems for a user so that they can reach their desired rating-group (next rating-group).

I just wanted to ask... did someone face issues where you clicked on 'Generate' button and you didn't get recommendations ?

Or any other issues / defects you found ? or want to give some different feedback regarding the recommended problems ?

Pls do let me know. Thank you !

Note: I'll use this blog to look into defects related to recommendation system.

Recommender can be found here : here

Hi Codeforces community, I have created a tool for helping out CF community — CPDojo.

This tool can be used for monitoring ourselves and also to filter problems.

Some of the features added as of now are:

  1. Problems filtering based on number of solves, problems tags and ratings. Like if you need problems which are solved by atleast X people and utmost Y people, then you can filter problems that way.

  2. You can also view how much problems you have solved between 2 time periods based on the problem ratings. This will help us to track exactly how many problems we solved during past 3 months and then we can make decisions based on that analytics.

  3. You can also view how many problems of particular type you have solved, which will eventually contribute to your progress tracking.

Sample screenshot:

I am planning to add additional functionalities too in future... If you have some interesting suggestions please do let me know :). Also let me know if you have any improvements that can add more value to the tool. Thank you !

Note : I am working on mobile UI currently. It is under development, so it is not recommended to view it in mobile. Thank you for your patience.
