How to write your research work in simple way I am a PhD student works in the theoretical computer science. I am facing a difficulty while I have to write my work in a good manner. I try to write but when other students, collegues read my drafts they are not able to understand the idea I want to convey. I have written one or two research paper in my previous years. I try to look at the research papers which I am referring for help, it gives me some help but not that much. The problem I am facing is not able to write the things in a simple way, some time mix the  things. To me it appears that writing is much more challenging than solving a research problem.

Question : How to write your research in a simple way? Simple just means  other people can understand my work and the idea behind it at least.
Use a hierarchical structure that is clearly shown to the reader.    https://www.amazon.com/Pyramid-Principle-Logic-Writing-Thinking/dp/0273710516  Make a bulleted outline of each section of work before writing.
Be honest and direct.  https://ocw.mit.edu/courses/media-arts-and-sciences/mas-111-introduction-to-doing-research-in-media-arts-and-sciences-spring-2011/readings/MITMAS_111S11_read_ses5.pdf
Look at the "directions to authors" for each journal you submit to and follow them rigorously, like a checklist.
Write frequently and get frequent feedback and incorporate it.  Look for those who are good writers to review your work.  


P.s.  I disagree with the advice to write in your native tongue and then have a translation made.  You will not learn well that way.  Stick to your flawed English but get better as you use it.  If anything being weaker in English will force you to a simpler sentence structure (fine).  Issues with clarity are very likely not the language problem but poor structure or poor logic.
