One significant area of research within graph algorithms is the study of spanners. A spanner is a subgraph that preserves the distances between nodes in the original graph, albeit with some ...

Spanners are usually fixed tools without an adjustable jaw, while wrenches have a movable jaw that can adjust to a range of widths. However, there are many types of spanners with various functions.

Hop Spanner: A type of spanner that ensures connectivity between points using a limited number of edges (hops). Separator: A subset of vertices in a graph whose removal disconnects the graph ...
