 DSTO > Publications > On the Suitability of NetLogo for the Modelling of Civilian Assistance and Guerrilla Warfare
The relative benefit of this assistance, measured as the number of UN peacekeepers surviving the peacekeeping operation, is recorded and analysed for statistical significance.
Within the limits of this study it is concluded that NetLogo is able to model the key interactions and behaviours between the protagonists in guerrilla warfare.
However, NetLogo is not designed or intended to capture the complex reality of warfighting and is thus best used to gain insight into the nature of guerrilla warfare rather than to provide concrete outcomes.

NetLogo is the highest-level platform, providing a simple yet powerful programming language, built-in graphical interfaces, and comprehensive documentation.
NetLogo is highly recommended, even for prototyping complex models.
Recommendations include providing basic documentation (a weakness of all platforms except NetLogo), strengthening conceptual frameworks, providing better tools for statistical output and automating simulation experiments, simplifying common tasks, and researching technologies for understanding simulation results and how they arise.

The NetLogo world is a torus, that is, the edges of the screen are connected to each other, so turtles and patches "wrap around".
NetLogo's design was driven by the need to revise and expand the language so it is easier to use and more powerful, and by the need to support the HubNet architecture.
We have expended every effort to make NetLogo model runs fully reproducible, but of course this can never truly be an iron-clad guarantee, due to the possibility of random hardware failure, and also due to the possibility of human error in the design of: your model, NetLogo, your Java VM, your hardware, and so on.

 Michael Agar: Agents in Living Color
In this article, the anthropological concept of 'emic' or 'insider's view' is used to foreground the value of learning what differences make a difference to actual human agents before building a model of those agents and their world.
The code is available on the Netlogo community models page (http://ccl.northwestern.edu/netlogo/models/community/Drugtalk) so interested readers can examine the model for themselves.
Finally I started working on my own in the Netlogo language (Wilensky 1999), making several changes to the Drugmart model that will be described in a moment.

While assembly doesn't suffer from the narrow applicability problem of StageCast and NetLogo in terms of the range of things that can be accopmlished in the language, it still fails to meet the goal of giving our students a practical programming skill.

 Emergence and Contingency/Purpose/Agency: An Exploration of an Intersection Between History and Biology/Neurobiology
In NetLogo, "turtle" is the name given to the agents to whom rules are attached, and who enact those rules in turn within the background environment of the program.
When observers first see a NetLogo simulation, they often anthropomorphize the action of the turtles, speaking in terms of the turtles’ desire to accomplish particular goals or create particular structures.
They will be bound by the same ruleset as the termites in NetLogo except that they will be allowed to choose the direction of their next move.

 josephson-cooperative
The NetLogo model interface is divided into four main areas: a set of sliders on the left change the simulation setting, while several buttons, sliders and switches on the bottom control how the simulation is run.
Of course, for heavy numerical work, a conventional language such as Fortran or C is still preferrable, for its raw speed and also because it is possible to run the simulation in unattended tasks, possibly collecting and analyzing automatically the results.
The real benefits of NetLogo are different: the language is very simple but also powerful and a complete simulation, comprising a fully interactive user interface, can be built with very few lines of code, making it an invaluable didactic tool or even a tool for rapid prototyping of an algorithm.

earlier look at NetLogo, we saw how to execute simple commands in the command center, how patches and turtles/agents work, and how to run models such as the Schelling Segregation model in the Models Library included with NetLogo.
Seth Tisue, one of the NetLogo developers, converted a Repast TSP to run in NetLogo!
The numbers are printed at the turtle’s position, so the edge turtle is halfway between the two node turtles and is long enough to connect them and has the correct “heading” to do so.

 Genetic Programming Demo
In many NetLogo models, agents are given predetermined rules, and then the emergent behaviors that form through the interactions of these agents are studied.
The NetLogo feature on which this whole model stands is the ability to take a string of text, and run it as NetLogo code.
Since NetLogo doesn't support any formal concept of code libraries, this separation is largely achieved through positioning of the code, naming conventions, and comments.
