Here are the files I have uploaded that you can try it with:

• test.xml – A simple graph where each node is connected to the following node.
• test-d.xml – Same as the previous one, but this one is directed.
• shorter.xml – Also simple, with each node connected to the next. Because of the weights, it is shorter to go the “long way” to get from n1 to n5, and you can watch the algorithm find this shorter path.
• negative.xml – Graph with a negative cycle.

Click here to run it in the full browser window. Or you can right-click that link to save it and provide it with your own GraphML files.

I’ve removed the voice-over from this presentation. The click sound-effect is still present if you click the full-screen link above.

Here’s the readme.

And here it is!

I can say with absolute certainty that ActionScript is not my favorite language to program in. But, I’ll write more on the ActionScript programming experience later.
