The m-agent is a generic component shipped with theĬore. Model ( Figure 3) only consists in a m-agent and a Model Artifact. Minimal exampleĪ minimal example is the launching of a NetLogo model from a We use this characteristic for retrieving and exchanging the walkers. Thus, after each step, the hidden walkers represent the walkers who leave the world. The walkers out of the world scope are hidden and die at the next simulation step. Figure 2: Petri network of a walker state The petri network in figure 2 represents a walker’s state.Įach place is a fulfilled condition and a transition is an event. When a walker overpasses the border of the world, in other words, is on a gray ground, it is hidden Therefore the count of walkers decreases over time. For each step – NetLogo tick – the hidden walkers die and the other ones move in a random direction. The model creates a pool of walkers – NetLogo turtles – positioned at the origin. This editor is not shipped with the Getting Started project (see NetLogo webpage). You can run the model located at My Models/Netlogo-Models/random_walk_1.nlogo via the NetLogo Editor ( Figure 1). Random walk modelĪt first, you can take a look about the model’s behavior. The tutorial can be done directly in this project, or you can create your own Maven project -see the ‘pom.xml’ file of MecsycoScholar project to have an example. Setupĭownload the MecsycoScholar project and import it in Eclipse (see the usage guide). The environment used in this tutorial is Eclipse 4.16.0 with the Java Development Kit 1.8. Some knowledge about multi-modelling, theĬoncepts, NetLogo modeling, the Java programming language and Maven could be helpful. It focuses on a technical and implementation viewpoint (how to code), neither modelling, nor meta-modelling viewpoints (how to model, why these choices). GIS Gradient Example provides another example of how to use the GIS extension.This document aims at explaining how to implement an application with the **įramework**. See the other GIS code example, GIS Gradient Example, for an example of this technique. This model doesn't do anything particularly interesting, but you can easily copy some of the code from the Code tab into a new model that uses your own data, or does something interesting with the included data. For example, you could modify highlight-large-cities to highlight small cities instead, by replacing gis:find-greater-than with gis:find-less-than. Most of the commands in the Code tab can be easily modified to display slightly different information. See the code tab for specific information about how the different buttons work. You can then use all other features of the mode. Select a map projection from the projection menu, then click the setup button. It provides a collection of different ways to draw the data to the drawing layer, run queries on it, and transform it into NetLogo Turtles or Patch data. This model loads four different GIS datasets: a point file of world cities, a polyline file of world rivers, a polygon file of countries, and a raster file of surface elevation. This model was built to test and demonstrate the functionality of the GIS NetLogo extension. Note: If you download the NetLogo application, every model in the Models Library is included.
