NetLogo for Mac6.2.0

Modeling environment for simulating natural and social phenomena.

What is NetLogo for Mac

NetLogo is a programmable modeling environment for simulating natural and social phenomena. It is particularly well suited for modeling complex systems developing over time. Modelers can give instructions to hundreds or thousands of independent "agents" all operating concurrently. This makes it possible to explore the connection between the micro-level behavior of individuals and the macro-level patterns that emerge from the interaction of many individuals.

NetLogo lets students open simulations and "play" with them, exploring their behavior under various conditions. It is also an authoring environment which enables students, teachers and curriculum developers to create their own models. NetLogo is simple enough that students and teachers can easily run simulations or even build their own. And, it is advanced enough to serve as a powerful tool for researchers in many fields.

NetLogo has extensive documentation and tutorials. It also comes with a Models Library, which is a large collection of pre-written simulations that can be used and modified. These simulations address many content areas in the natural and social sciences, including biology and medicine, physics and chemistry, mathematics and computer science, and economics and social psychology. Several model-based inquiry curricula using NetLogo are currently under development.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

What's new in NetLogo

Version 6.2.0:
Features:
  • The models library now shows code examples that come with extensions installed through the extensions manager.
  • We now bundle the Liberica OpenJDK Java runtime instead of the Oracle Java runtime, which has a less restrictive license.
  • The mean primitive will now work on lists that contain non-numbers as other number processing primitives do.
  • The extensions manager can be disabled with a command-line switch to avoid network traffic or to lock down installed extensions.
Bugfixes:
  • We’ve made changes to how we bundle NetLogo on macOS in order to satisfy Apple’s package notarization process for detecting malware. NetLogo now runs without any special workarounds, as long as your macOS settings allow running software from identified developers.
  • When first opening a model and installing a new extension for it through the extensions manager prompt, the model widgets would not be usable until the model’s code was recompiled. Now the model will be ready to use right after the extension is installed.
  • When using in-cone on wrapped worlds, occasionally turtles at the very edge of the wrapped cone would be missing from the results.
  • When using in-radius on a patch to get nearby turtles, sometimes turtles at the edge of the radius would be missing from the results.
  • The performance of a turtle lookup by breed and who-number, like sheep 10, could take an unreasonable amount of time.
  • Models with a large amount of code (5000+ lines) would take a very long time to check and compile.

This is fantastic! The included sample simulations offer unique insights into many questions such as: Do bird flocks have a leader? How much would you stand to save by upgrading the insulation of your home? How do traffic jams develop and resolve? Watch as hundreds or even thousands of simulated animals, molecules, cells or guests at a party interact. Turn a knob or push a slider and the patterns change as each individual element in the simulation alters its behavior. There is probably no better illustration of the ways complex behavior can arise out of nothing but large numbers of independent actors each doing its own thing by following simple rules. Incredibly mind-expanding stuff!
