PageRanking in Mathematica
In the " Advanced Topics in Information Retrieval " course I'm taking this term, we had a light introduction to PageRank algorithm and I wanted to redo the relevant slides and solve some exercises in Mathematica - which I happened to learn while providing programming support to my best friend in her endeavor of mathematical modeling and simulation of drug resistance in infectious diseases !. Here it is as PDF and Mathematica Notebook ! It's truly amazing what you can achieve with Mathematica with tiny amounts of code. I find the selection of functions provided in version 7 and their implementations to be stunning examples of programming done right .
