Boundary (graph theory)

In graph theory, the outer boundary of a subset S of the vertices of a graph G is the set of vertices in G that are adjacent to vertices in S, but not in S themselves. The inner boundary is the set of vertices in S that have a neighbor outside S. The edge boundary is the set of edges with one endpoint in the inner boundary and one endpoint in the outer boundary.
