This applet determines a path from a start city to a finish city in which each edge's distance is less than the previous edge's distance. To start, enter the start city and end city. (All city names are not case sensitive. The applet will interpret, for example, NYC and nyc to be different cities). Then click enter information. Next, enter the edges in the network, one at a time (enter a start city, an end city, and the distance between them, then click enter information). For demonstration reasons, there is a limit of seven cities in the network. The network will be drawn as the information is entered. When you have entered all the edges in the network, click the start animation button. Green city names represent cities on the correct path. Red city names represent backtracking.

Please do not resize the browser window during the animation.

To restart the applet, click the broswer's refresh/reload button. To quit, just close the browser.
