Isoperimetric Tools

This webpage offers a set of online tools for dealing with isoperimetric-type problems on graphs and posets.
In the future, I plan to implement more graph and poset algorithms related to my current interests.

To run these tools, you have to have Java version 1.5 or later installed on your computer. Your browser has to report a MIME type of application/x-java-jnlp-file for files with extension jnlp (JNLP is a short for Java Network Launch Protocol). Usually, the browser is automatically configured for JNLP in case the Sun JRE is installed. You can check/configure the browser by assigning the javaws application (a part of JRE) with the file type application/x-java-jnlp-file.

All your comments, suggestions, and reports on problems with these tools will be greatly appreciated.
You can email me them at
