For instance, the representation suggested by van Rossum, in which a hash table is used to associate each vertex with an array of adjacent vertices, can be seen as an example of this ...

the size of the adjacency list which is Θ(E). Since the initial loop takes Θ(V) time, the total runtime is Θ(V+E). This is considered linear in terms of the size of the input adjacency-list representation. So if there are lots of edges then E dominates the runtime, otherwise V does.the size of the adjacency list which is Θ(E). Since the initial loop takes Θ(V) time, the total runtime is Θ(V+E). This is considered linear in terms of the size of the input adjacency-list representation. So if there are lots of edges then E dominates the runtime, otherwise V does.

For example, consider the following directed graph representation... Adjacency List. In this representation, every vertex of a graph contains list of its adjacent vertices. For example, consider the following directed graph representation implemented using linked list... This representation can also be implemented using an array as follows..

Prim's algorithm using adjacency list. Prim's is an greedy algorithm, which are used to find a minimum spanning tree of a weighted undirected graph.
