Vertex Cover

Vertex Cover is a concept from graph theory, a field in mathematics and computer science. In a graph, which consists of dots (vertices) connected by lines (edges), a vertex cover is a set of vertices such that every edge in the graph touches at least one vertex from this set. This means that if you picked all the vertices in your cover, you would have a point of contact for every connection in the graph. Vertex covers are important in various practical applications, such as network security, resource management, and solving optimization problems in computer science.
