This page was automatically generated by NetLogo 5.0.1.

The applet requires Java 5 or higher. Java must be enabled in your browser settings. Mac users must have Mac OS X 10.4 or higher. Windows and Linux users may obtain the latest Java from Oracle's Java site.

In order for this to work, this file, your model file (vie.nlogo), and the files NetLogoLite.jar and NetLogoLite.jar.pack.gz must all be in the same directory. (You can copy NetLogoLite.jar and NetLogoLite.jar.pack.gz from the directory where you installed NetLogo.)

On some systems, you can test the applet locally on your computer before uploading it to a web server. It doesn't work on all systems, though, so if it doesn't work from your hard drive, please try uploading it to a web server.

You don't need to include everything in this file in your page. If you want, you can just take the HTML code beginning with <applet> and ending with </applet>, and paste it into any HTML file you want. It's even OK to put multiple <applet> tags on a single page.

If the NetLogoLite files and your model are in different directories, you must modify the archive= and value= lines in the HTML code to point to their actual locations. (For example, if you have multiple applets in different directories on the same web server, you may want to put a single copy of the NetLogoLite files in one central place and change the archive= lines of all the HTML files to point to that one central copy. This will save disk space for you and download time for your users.)
