I don't get this (Reverse-delete algorithm). Can someone give me an example, please.

I guess we will need more details to help you

A lot of algorithms may desserve that title and

Reverse-delete algorithm is used to get minimum spanning tree of a graph.

Reverse-delete algorithm algorithm is a greedy algorithm, choosing the best at a given point not putting future in mind. It is the reverse of Kruskal's algorithm (another greedy algorithm to find a minimum spanning tree but it starts with an empty graph and adds edges) while the Reverse-Delete algorithm starts with the original graph and deletes edges from it.

Algorithm:

- Start with graph G, which contains edges E.

- Get high E weight and check if deleting it will disconnect the graph then delete if not.

Is that what you where asking for?
