First, have a look of the structure of the BehaviorSpace Table output data. Sure, you can keep the Spreadsheet format as well, but in R, the Table output is more suitable. Firstly, we need to export a data in table output from NetLogo BehaviorSpace. The following will be a description of how this model operates along with suggestions as to how it might be set-up, modified or extended to better portray a particular market. A complete beginners guide how to read and use NetLogo BehaviorSpace data in R. It is certainly the goal of agent-based modelers in general that, given a sufficient set of agent rules, any complex system can be modeled or at least accurately mimicked. It is a ‘general purpose’ example of how an agent-based model can be used to investigate a complex problem such as the difficulty in the allocation of resources for exploration or exploitation. This model is not intended to represent any specific market or to validate any existing theory. Any created model can be easily distributed for use without the need of end-users downloading the NetLogo tool itself. It is Java based and thus takes advantage of the programming ease of an interpreted language and the speed of a compiled language. Be introduced to NetLogos Ants Model, learning what it does and the influence of its parameters in its behavior. Search: Predator Prey Simulation Online Learning. The NetLogo agent-based modeling tool was chosen because it is easy to program, well documented and available for free download from. (factorial-type) search, you should use the BehaviorSpace tool thats built-in to NetLogo. This feature coupled with any statistical package provides for a potentially extremely effective modeling technique for this very complex issue. Design a quantitative measure for a behavior of interest. The ‘Behavior Space’ feature of NetLogo allows the user to map performance and market share in space of all 16 control ‘dimensions’. This simple agent-based model has 16 settable parameters. The agent-based model approach to the exploration / exploitation dilemma allows for a massively complex model to be developed through relatively simple programming. : Java heap spaceĪt .run(JobThread.The NetLogo Exploration / Exploitation agent-based model has been designed for the observation of how different resource allocation strategies can affect performance and market share in differing consumer markets and competition environments. : Extension exception: Java heapĪt ._extern.perform(_extern.java:40)Ĭaused by: : Java heap space Run #8, RUNTIME ERROR: Extension exception: Java heap spaceĮrror while observer running GIS:APPLY-RASTERĬalled by procedure SETUP-FOR-BEHAVIOR-SEARCH ![]() 0$mcV$sp.apply(JFunction0$mcV$sp.java:12)Īt $Catch.apply(Exception.scala:224)Īt $.handling(Exceptions.scala:41)Īt .run(JobThread.scala:66) $Command.perform(GISExtension.java:61)Īt ._extern.perform(_extern.java:36)Īt .stepConcurrent(Context.java:107)Īt .step(ConcurrentJob.scala:65)Īt .runPrimaryJobs(JobThread.scala:133)Īt .$anonfun$run$1(JobThread.scala:68)Īt $$Lambda$50/1989099353.apply$mcV$sp(Unknown createRendering(RasterDataset.java:300)Īt .resample(RasterDataset.java:543) createWritableRaster(PlanarImage.java:1982)Īt .copyData(PlanarImage.java:2319)Īt .copyData(PlanarImage.java:2279)Īt .copyData(RenderedOp.java:2285) How to explore your model in four steps: Choose model parameters to vary and what ranges are allowed. createTile(RecyclingTileFactory.java:389) /netlogo: Influenced by Logo, StarLogo: NetLogo is a programming language and integrated development environment (IDE) for agent-based modeling. BehaviorSearch interfaces with the popular NetLogo ABM development platform, to provide a low-threshold way to search for combinations of model parameter settings that will result in a specified target behavior. createDataBuffer(BandedSampleModel.java:206) ": Java heap spaceĪt .(DataBufferDouble.java:86) I'm trying to run my netlogo model (with gis extgension) usingīehavior-space and it repots me (see below).

If you still get out-of-memory errors, you can The short answer is to modify your NetLogo.cfg file and change "-Xmx1024m" to See the FAQ section on "How big can my model be?"
