What Does It Mean For A Graph To Be Connected. In short you have to have a reason for even plotting. The connectivity number λG is defined as the minimum number of edges whose removal from G results in a disconnected graph or in.
A graph that has a separation node is called separable and one that has none is called nonseparable. Consider an adjacency matrix where the elements are either 1 to indicate the presence of an edge or 0 to indicate the absence of an edge. The elements of such a path matrix of this graph would be random.
Later on we will find an easy way using matrices to decide whether a given graph is connect or not.
Because any two points that you select there is path from one to another. A graph is said to be weakly connected if there doesnt exist any path between any two pairs of vertices. The null graph satisfies that criteria so it is connected. Lets try to simplify it further though.
