I am currently writing a technical report. While writing the "Related work" section, I often need to write expressions as shown in the title:
"The author means that this algorithm is not suitable in all cases.",
"The author writes that..." or
"The author points out", etc.
As I am not a native English speaker, I find it hard to vary my language. I know I saw a list of many possible ways of refering to something other people has said or written, but it was not in English and it would probably not be directly translateble.
I am so sorry if there exist another question about this. Please let me know in that case, but I don't know what keywords to search for in this case. What other ways are there of refering to something someone has written or found out in their work, and what is this way of referring called (what can I search for)?
