+## Performance based problem recommendation
+<br>
+
+## About
+1) The recommendation is independent of the type of problem, it's completely dependent on the language in which the user has solved the previous problem.
+2) The recommendation system (success score) is based on formula:- 1/(1+TS-PS);
+where TS=successful submissions/total submissions,
+PS=successful submissions for a particular language/total submissions for particular language
+3) For training the model ,KNN algorithm is used.
+4) Based on the calculated success score for a particular problem, the user will be recommended a problem having a similar success score. So the user will be recommended with problems having a similar success score to that of the previous problem solved based on language used, irrespective of type of problem.
+5) The actual flask application is private which is using this methods to recommended problems.
