I found an error in one of the algorithms, fixed it, and tried to make a pull request. However I already have a previous pr open so I'm unable to make another one. Should i just wait, or close my earlier one?

Also I noticed your conversation about rejecting prs without doctests which makes sense. In this case, the error I've fixed is in a file that I think needs quite a few more changes, and it doesn't yet have doctests included. However, I wanted my first pr for this file to be just a simple fixing of the error. Adding doctests will unfortunately be a little more complicated since the original code writer added a lot of print statements within the functions.
