    Hello, can someone explain how to do this, and what the thinking behind it is please?

    https://i.gyazo.com/4127fc03a6a2930e...e78c8df57e.png

    I am really not understanding this chapter at the moment, I don't know how to show that there are 4 spanning trees or whatever at all, and the example doesn't help whatsoever.

    Thank you.

    You join the nodes with the smallest distance/weight between them but you must not do a loop.

    So you could do AtoD then BtoC, then CtoA BUT now you can't use the CtoD because you would have a loop. Then you'd do EtoF , CtoE Finished. Every node can be got to.

    The next time round swap the CtoA route for CtoD but keep the rest of the tree the same.

    There are alternative routes in other parts of the tree.

    I hope this explanation is good enough.
