WebAn edge cover of a graph \(G\) is a set of edges \(E_c\) where every vertex in \(G\) is incident (touching) with at least one of the edges in \(E_c\). This means that each node in the graph is touching at least one of the edges in the edge covering. Edge cover is a topic in graph theory that has applications in matching problems and optimization problems.
