A tutorial and bonus mini-assignment (worth up to three bonus marks) on the PageRank algorithm has been posted. It’s based on the material in today’s PageRank session. If you weren’t able to make the session, there should be enough information in the walkthrough for you to be able to take a stab at the questions anyway.
If you’re interested, here is a zip file of the MATLAB functions I used in the session. (A warning that some of the plotting commands may not work as expected in Octave or older versions of MATLAB.)
