In describing an algorithm, I feel I repeatedly use "After doing this, the algorithm do that". I look for alternative ways to say such sequences. For example I wrote:
After obtaining the Post-Matches rules, the algorithm performs the extraction command and the post-assignments of both Pre-Matches and Post-Matches
I think of writing it as:
Once the Post-Matches rules were obtained, the algorithm performs the extraction command and the post-assignments of both Pre-Matches and Post-Matches.
Are they equivalent? What are other ways to say such sentences?
