Users Group

A good place to ask NetLogo programming questions is Stack Overflow.

But there is also an on-line NetLogo Users Group where you can discuss thoughts and questions about NetLogo with other users via email or the web. Follow the above link to browse the group, or follow this link to join.

Developers Group

If you're a Java or Scala developer interested in NetLogo development, NetLogo internals, the NetLogo source code, or NetLogo API's, browse or join netlogo-devel.

If you're trying to make your own NetLogo extension or control NetLogo from Java code, netlogo-devel is the right group.

Educators Group

netlogo-educators is intended to support questions pertaining to using NetLogo in the classroom. Curriculum design and implementation with NetLogo is the focus of this group. Feel free to post a question or join the discussion. Follow the above link to browse the group, or follow this link to join.

Live chat (IRC)

For live about chat about NetLogo (including NetLogo modeling and development work on NetLogo itself), use any Internet Relay Chat (IRC) client to join the #netlogo IRC channel on the Freenode network.

Extensions

  • NetLogo extensions

    Add-ons that extend the NetLogo language with new primitives. (This wiki page is community-editable.)

Libraries

  • NLoops
    by Simon Lynch

    NLoops is a partial objects layer for NetLogo. It is written in NetLogo (not as a Java extension) so it is used as a .nls include file. Includes tutorial and reference guide.

  • RK4 (Runge-kutta 4th Order Method)
    by Pierre-Olivier Chasset

    RK4 performs an iterative method for the approximation of solutions of ordinary differential equations: the Runge-Kutta 4th Order Method. It works with any number of equations and any number of variables.

  • TIF (Testing is fun)
    by Pierre-Olivier Chasset

    TIF (tif.nls) is a library for the simulation software NetLogo [1] helping to write unit tests. Compared to the extension Test of NetLogo, this module is written in NetLogo and its usage is fun. It is largely inspired from the testthat package [2] for the statistical software R. License: GNU Affero GPL..

Tools

  • BehaviorSearch
    by Forrest Stonedahl & Uri Wilensky

    BehaviorSearch is an add-on for NetLogo that can help automate the exploration of agent-based models (ABMs), by using genetic algorithms and other heuristic techniques to search the parameter-space.

  • IODA for NetLogo
    by Sébastien Picault and Philippe Mathieu

    NetLogo implementation of the "Interaction-Oriented" methodology for the design of agent-based simulations ("IODA"). Includes an extension, an include file, several programming examples, and detailed documentation.

  • OpenMOLE
    from L'institut des Systèmes Complexes – Paris Île-de-France

    Open MOdeL Experiment is a generic workflow engine providing distributed computing facilities. Framework for defining Design of Experiment (DoE) on simulation models, including NetLogo models.

  • MEME (Model Exploration Module)
    by AITIA International

    A BehaviorSpace-like tool that supports running parameter sweeping experiments and analyzing the results. Works with NetLogo as well as other ABM tools such as Repast.

  • RNetLogo
    by Jan C. Thiele

    "Interface to embed NetLogo into the R environment with headless (no GUI) and interactive GUI mode. Provides functions to load models, execute commands and to get values from reporters." (see also the NetLogo-R Extension)

  • NetLogo-LaTeX
    by Martin Dobiasch

    Use cases: Create models including documentation. Include NetLogo source code in a paper automatically.

  • BODNetLogo
    by Mike Brooks

    "BODNetLogo Integrates the BOD agent design methodology and the NetLogo simulation platform... Behavior Oriented Design (BOD) is a methodology for developing control of complex intelligent agents, such as virtual reality characters, humanoid robots or intelligent environments. It combines the advantages of Behavior-Based AI and Object Oriented Design."

  • NetLogo Publication Script
    by Steven Brewer

    A script for simplifying the publication and updating of NetLogo models on the web.

  • NetLogo Obfuscator
    by Peter Brooks

    Creates “an obfuscated Code section to make the source code as indecipherable as possible, while allowing the project to work identically to the original”. Includes source code.

  • NetLogo Cluster
    by Albert Jornet Puig

    A tool to automatize the launch of experiments on an HPC with a SGE scheduler for Netlogo ABM software.

Editor support

  • Emacs mode
    by Sebastien Rey

    Syntax-colors NetLogo code in the Emacs text editor.

  • NetLogo VIM Syntax File
    by Steven T. Stoddard and Alan Isaac

    Syntax-colors NetLogo code in the the VIM text editor.

  • BBEdit Language Module
    by Dave Hurley

    Syntax-colors NetLogo code in the the Mac text editor BBEdit. (This is no longer being maintained.)

Books

in English:

  • Agent-Based Spatial Simulation with NetLogo: Introduction and Bases (forthcoming in 2015)
    by Arnaud Banos, Christoph Lang, and Nicolas Marilleau

    “illustrates, using the heavily utilized free software NetLogo, the main principles of agent-based spatial simulation. It will provide theoretical and conceptual backgrounds as well as algorithmic and technical insights”

  • Spatial Simulation: Exploring Pattern and Process (2014)
    by David O'Sullivan and George Perry
