## Static Source Code Analysis Tools and their Application to the Detection of Plagiarism in Java Programs

July 10, 2008 - 18:11

This project develops a system for detecting plagiarism in sets of student assignments written in Java. Plagiarism is viewed as a form of code obfuscation where students deliberately perform semantics preserving transformations of an original working version to pass it of as their own. In order to detect such obfuscations we assume we have a set of programs in which we attempt to find transformations that have been applied. We investigate tools for static analysis and transformation of Java programs to build a system for plagiarism detection.

## Artificial Ants: Simulating Ant Behaviour and Investigating Applications In Computing

July 10, 2007 - 18:15

Ants are excellent route finders, with the ability to find the shortest path between their nest and a food source, by using pheromone trail clues to organize themselves collectively. By applying behaviour observed in ant colonies to the field of computing, these ant-based techniques can provide a base for network routing algorithms, as well as algorithms to solve graph problems such as the travelling salesman problem.

During my third year at Goldsmiths I studied data compression. Here's my implementation of LZW in PHP.

## Simple PHP Shopping Cart Tutorial

February 2, 2006 - 00:00

This is a very simple shopping cart that stores the product ids in an associative array. The keys are the product id and the values are the quantity of that particular product.

To store information between pages we can use the $_SESSION superglobal variable, by using an element of the array like this:$_SESSION['cart'] - this is where our cart will be stored.
