During this term I took part in a course that was both a (research) project/presentation/lecture thing, which was fun but also a lot of work.
I’ve already written about one mathematical aspect of it in my post about Analysis, Cauchy-Schwarz and Reciprocal Sums.

The project was about optimizing semi-conductor wiring placement. We wrote a small paper about our findings and the work it was based one – you can look download it here.

We also created a self-running presentation that doesn’t contain any Maths at all but makes heavy use of Flash animations (which were exported to .gif manually, which was a huge pain in the ass, which I will never do again if possible) to visualize all the concepts and algorithms.

You can download a PowerPoint 2007 (.pptx) version here or one that works with PowerPoint 2003 here.

For the Student’s I sat down and wrote a small Flash application to show the algorithms at work. It’s not obvious how it works, so let me explain the major points:

• On the right you have a number of panels that you can enlarge by clicking on the small button in the upper right of each panel.
• The upper three panels show different views of the same dataset. They will all be updated as you run the algorithm step by step.
• The fourth panel lets you change the number of wires and/or their activity.
• The last panel shows the electrical field that is created by one active wire in the center. It was created using MatLAB. I’ve also uploaded the script here.

Last but not least I’ve also uploaded the current version of all my .fla and .as files. You can download it here.

ActionScript is a nice language and you can quickly learn it using the available resources from Adobe.
While ActionScript 2.0 is arguably weird, ActionScript 3.0 is quite logical and it’s syntax is straight-forward and consistent, too. You can’t say that about the IDE (Flash CS4), which is braindead, but if you’re only interested in writing ActionScript code, FlashDevelop is an excellent and free alternative.

This is it for now, maybe I’ll play around with Flash some more another time.
Cheers,
