I would like to write about different methods. I need to write them in a good English way. I tried to use "one" and "another" but do not know if this is a correct structure or not?
My short paragraph:
One existing method is a method A introduce by author C. Another method is the one introduced by author D. Their method is simple and fast. Another method was introduced by E.
In the last two sentences, I used the word, "Another". So, I feel that I just repeat the opening word of my two sentences. By the opining word I mean One and Another.
How could I list different methods in a paragraph in a good English structure? any help, please?
