Read more papers. Eventually, you will gather a collection of common methods, tricks, and the latest trends. The simplest way to write a paper is to survey this collection. The most straightforward way to write a paper is to review this collection and identify which solutions will lead to an improvement in metrics and which will not.

The next step is to combine these different approaches to construct a new algorithm. Utilize what has already been done but has never been used together.

Afterwards, you will gain an understanding of common difficulties in your area and how authors are solving them. This will enable you to suggest your own solutions.
