Masato's Unicursal Figures Program
Finding Euler Circuits
Below is a Java applet for computing Euler circuits and Euler paths.

Here are the instructions:

  1. Click a mouse button at all points where you want to put vertices.
  2. Click NEXT.
  3. Click the starting and ending vertices of all edges in your graph.
  4. Click NEXT.
  5. If there is no Euler circuit or path, the program will give a message saying it failed. Click RESET to start again.

    If there is one, it will give a message saying it succeeded. Then click SHOW RESULT to show the successive steps of the Euler path.
