This project was due last week, and I had it working except for a minor bug, which is why it hasn't been posted until now.  The final debugging of this annoying little issue is courtesy of Kristopher Windsor.

This is a simple implementation of the original Google PageRank algorithm, using integers in place of URLs, relying on the BigMatrix class (included inside the Google.java file) for data storage.  There are enough comments that it should be self-explanatory.

All code is now available via SVN, and a web browsing utility.

Note:  I am not advocating using this code in place of doing your own homework, or in any situation other than pure interest.  However, in the event that you do, I am not responsible for any resultant issues (legal, moral, or ethical) that may arise.  Finally, I am not presenting these as perfect cases, the best way to approach the problems, nor the fastest.  They are, simply, viable solutions.

Old Content posts are leftovers from a less structured, less civilzed era that are kept for posterity.
