Java System Properties and how to use them - NetLogo/NetLogo GitHub Wiki

NetLogo uses Java system properties to change the way that it operates. These can be edited in NetLogo.cfg (when running the desktop application) or in the headless launcher (when running from the command line). The following is a list of properties that NetLogo uses, possible options available, and how it effects NetLogo's execution.
