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.

Tools

• 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.

• 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.

• 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)

  by Steven T. Stoddard

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

• NetLogo Obfuscator
  by Peter Brooks

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

Books
