I think this is the best place to contact the original authors. The link to Vladimir Yaroslavskiy's original whitepaper describing the algorithm and its proofs was, unfortunately, broken. Using Archive.org's Wayback Machine, I was able to get the last known revision. I reformatted the document in LibreOffice for ease of reading, and fixed some minor grammatical errors.
I also implemented the algorithm in an open-source (MIT License) C++ library, which I hope to release in the coming few months. In order to make this algorithm and its proofs more easily accessible, I would like to make the revised whitepaper publicly and freely available from my own web servers, but I wanted to check with the original author(s) first. Furthermore, I wanted to find out if there have been any revisions since the 22 September 2009 version of the whitepaper I acquired. Thank you in advance!
