We're excited that you're learning NetLogo! This lecture is part of the University of California wide online course on Computational Social Science (UCCSS), produced with input from Professors from all. For example, if you ask for betweenness centrality with "directed links" selected in the chooser, but the network on the screen is undirected, the betweenness centrality values will all be zero, because the algorithm only takes directed links into account. . Here is an example: a frog breeding model used in critical management decisions for major rivers in California. NetLogo is a programming language and integrated development environment (IDE) for agent-based modeling.

For example, the following two lists would map all of geographic (latitude and longitude) space in degrees to NetLogo world space, regardless of the current dimensions of the NetLogo world: (list -180 180 -90 90) (list min-pxcor max-pxcor min-pycor max-pycor) see what happens or you can write brand new code. Iterated prisoner's dilemma, with hatching and death. In our example, the ants represent the turtles, and patches are the individual squares that make up the 2D grid. The model also tracks the effects of the perturbations. In general, this forum is to be used for solving specific problems that you run into rather than an open-ended request for help. Partnership.
