Trouble Running Our Netlogo Models / Java Applets?

Java has upgraded its security, so for some PC browsers, you will need to take steps to run our Playground's Netlogo models (Java applets), such as

  • The World of Langton's Ant: What is "purpose" and "purposeful" behavior and does one imply the other?
    an experiment with models, requires Java capable browser

  • Thinking About Segregation and Integration: Why do people cluster with others with similar characteristics?
    an experiment with models, optional: Java capable browser. Now upgraded to NetLogo 6 and we recommend downloading NetLogo and running the model on local machines. Links for downloads are provided with the experiment.

  • Seeing More Than Your Eye Does: Does your brain make up stories? A "blindspot" experiment.

1) update Java to the most recent release (you may have already does that step)

2) add our site to the Java exceptions list. Instructions for doing this are here:

The quick summary:

  • Start menu -> Java -> Configure Java,
  • Security tab,
  • Edit site list,
  • Add
  • Enter:  as one of the exceptions
  • Save
