Step 1First, the number of nodes desired in the entire completed graph must be selected from the pulldown menu at the top of the applet space. The default is 5 nodes.
The number of nodes must be selected before any graph drawing is done. This is necessary because upon selection the graph canvas is reset and cleared, and any graph data is lost.
Step 2Second, the nodes are placed on the graph canvas. This is done simply by moving the mouse cursor to the desired location and clicking the mouse. If nodes are placed incorrectly, or a different configuration is desired, any node can be moved at any time by holding down the SHIFT key and dragging the node to its new location.
Step 3Third, the edges are placed on the graph canvas. This is done by placing the mouse over the starting node and dragging the edge to any other node. Note that nodes may still be moved even with edges connected to them by holding down the SHIFT key and dragging the node to its new location. Also, edges can be removed by first clicking on the edge to highlight it and then pressing the DELETE key.
Step 4Once the graph is complete, the graph data is then submitted to the RIOT server by pressing the SUBMIT button at the bottom of the applet space. The message Please Wait...our server is processing your submission will appear until the completed solution returns. The solution will consist of a set of GREEN nodes and a set of BLUE nodes. The cut edges between the two sets will be highlighted in RED.
That's all there is to it!To see a graphical demo of these instructions, go to the RIOT Edge Connectivity Applet Demo page. To try the applet out, go to the RIOT Edge Connectivity Applet.
