How to publish at a top-tier (A*) AI conference?

This year I published at IJCAI-2022 (acceptance rate 15%). My article was selected for a long oral presentation (170/4535). I am the sole author of my article. (https://www.ijcai.org/proceedings/2022/0387.pdf)

The information in the blog could be used by anyone, but I have written this piece particularly for the current and the prospective Ph.D. students who are aiming for their first breakthrough.
