The Euler Graph Tool

This tool consists of two Flash player files that can be used by an instructor to create simple graphs for which students can search for Eulerian circuits or trails. An example of the finished application is shown below. Try the interface to get a sense for what you are building...

The Instructor first runs the Flash applet GraphMakerEuler.html to create a graph using simple drag-and-drop interface. Once the graph is finished the Instructor is given a line of text data that can be transferred to a file named euler.xml in between tags <graph> and </graph>. This process can be repeated indefinitely by adding more <graph> </graph> tags.

Next the Instructor places the files EulerGraphsXML.swf, EulerGraphsXML.html and euler.xml in the same directory. Additional instructions or navigation can be added to the EulerGraphsXML.html file, if deemed appropriate. When a student accesses this file, he or she will see exercises like the example shown above presented in random order.
