Operating Systems: Windows All

This application allows you to study the envintonment using the 3D models.

NetLogo is an application that allows you to create your own virtual environments by simulating natural and social phenomena.

NetLogo is particularly well suited for modeling complex systems developing over time. Modelers can give instructions to hundreds or thousands of "agents" all operating independently.

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 can also power a classroom participatory-simulation tool called HubNet. Through the use of networked computers or handheld devices such as Texas Instruments graphing calculators, each student can control an agent in a simulation.

NetLogo is the next generation of the series of multi-agent modeling languages that started with StarLogo. It builds off the functionality of our product StarLogoT and adds significant new features and a redesigned language and user interface.

NetLogo Description

Here are some key features of "NetLogo":

Programming:
· Fully programmable
· Approachable syntax
· Language is Logo dialect extended to support agents
· Mobile agents (turtles) move over a grid of stationary agents (patches)
· Link agents connect turtles to make networks, graphs, and aggregates
· Large vocabulary of built-in language primitives
· Double precision floating point math
· First-class function values (aka tasks, closures, lambda)
· Runs are reproducible cross-platform

Environment:
· Command center for on-the-fly interaction
· Interface builder w/ buttons, sliders, switches, choosers, monitors, text boxes, notes, output area
· Info tab for annotating your model with formatted text and images
· HubNet: participatory simulations using networked devices
· Agent monitors for inspecting and controlling agents
· Export and import functions (export data, save and restore state of model, make a movie)
· BehaviorSpace, an open source tool used to collect data from multiple parallel runs of a model
· System Dynamics Modeler
· NetLogo 3D for modeling 3D worlds
· Headless mode allows doing batch runs from the command line

Display and visualization:
· Line, bar, and scatter plots
· Speed slider lets you fast forward your model or see it in slow motion
· View your model in either 2D and 3D
· Scalable and rotatable vector shapes
· Turtle and patch labels

Web:
· Models and HubNet clients can be saved as applets to be embedded in web pages (note: some features are not available in applets, for example 3D)

APIs:
· controlling API allows embedding NetLogo in a script or application
· extensions API allows adding new commands and reporters to the NetLogo language; open source example extensions are included

Requirements:
· Java Runtime

What's New in This Release:
· many bugfixes
