As I had said in my previous post, I am very busy this time. Now, you are going to see why

Lately, I decided to learn more about computation models. This will probably be reseach focus in the upcoming years. I created two models, which I want to present to you. The models were created using NetLogo. NetLogo is a very simple language based on Logo. It is specifically for creating agent-based models. The two best features are that its programs can be exported and run on the internet in a simple java interface and that it can be connected to mathematica via tha MathLink. Mathematica not only is a very powerful application, but, it can also be connected to other computer languages, like those of the .NET protocol. This expands the horizon of possibilities.

The first model I made, is called the Three Species model. It’s a model where there are three species, the sugar eaters, the meat eaters and the grass eaters. These species, eat resources on the map, kill each other and reproduce asexually like bacteria. The model has many parameters and may seem a little bit confusing at the beginning. The reason I made so much parameters was to study the functions of NetLogo.

Don’t get too confused. I have incorporated detailed instructions on how to use the model inside the model.

The other model I created, is called the Walker Traffic model. It was based on a native model of NetLogo called traffic (simple). It has an one way road, and walkers that want to go across. It is simpler than the previous model. Not only it has fewer parameters, but it’s behavior is simpler as well. The three species model contains many stochastic interacting elements that produce all sorts of interesting dynamics. In fact, you’ll see that even if you hold all the parameters the same, the results each time change. On the other hand, the walker traffic model has simple dynamics that, I suspect, could be described by a stationary law.

My models are top baby!!!
