I have a good background in mathematics and combinatorics is my forte, to be honest. When I read the description of this project I felt like this project is the one for me. I have solved the various issue and most of my PRs are merged (around 17). I work religiously and try to contribute as much as possible. I am going to start writing my proposal today. I wanted to know what is your primary criteria for acceptance. What do you expect from a student and what should an applicant show in his proposal? What are you looking for?
