When starting off the agents, the agents will then need to be defined further, by a direction for example. Individuals that are close to one another are defined and named as the following. These can be of any names, if the breeds are other than turtles. The opening statement is to ‘breed.’ ‘Mice’ and ‘mouses’ sets out the program language, of having both a family and an individual. Development has been funded by the National Science Foundation and other foundations.īreed creating the breed of catsīreed creating the breed of mice NetLogo was designed and authored by Uri Wilensky, director of Northwestern University’s Center for Connected Learning and Computer-Based Modeling. NetLogo comes bundled with a large library of sample models covering many domains in natural and social science. Many teachers make use of NetLogo in their curricula. NetLogo is in use in a wide variety of educational contexts from elementary school to graduate school. It is freely available from the NetLogo website. NetLogo has many thousands of active users. 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. Modelers can give instructions to hundreds or thousands of independent “agents” all operating concurrently.

It is particularly well suited for modeling complex systems developing over time. Beyond exploration, NetLogo enables the quick and easy authoring of models. It comes with an extensive models library including models in a variety of domains such as economics, biology, physics, chemistry, psychology, system dynamics and many other natural and social sciences. The NetLogo environment enables exploration of emergent phenomena. NetLogo was designed in the spirit of the Logo programming language to be “low threshold and no ceiling,” that is to enable easy entry by novices and yet meet the needs of high powered users. It is authored by Uri Wilensky and developed at the CCL. It also powers HubNet participatory simulations. It is used by tens of thousands of students, teachers and researchers worldwide. NetLogo is a multi-agent programmable modeling environment. _ifelse distancexy mouse-xcor mouse-ycor if more is than _set heading towardsxy mouse-xcor mouse-ycor_ if the fistance of xy cords sre biger than the radius then turtles will have to walk to become closer.
