**Adjacency List Graph representation on python Code**

Data to initialize graph. If data=None (default) an empty graph is created. The data can be an edge list, or any NetworkX graph object. If the corresponding optional Python packages are installed the data can also be a NumPy matrix or 2d ndarray, a SciPy sparse matrix, or a PyGraphviz graph.... Adjacency List. Lets consider a graph in which there are N vertices numbered from 0 to N-1 and E number of edges in the form (i,j). Where (i,j) represent an edge from i th vertex to j th vertex.

**algorithm Edge lists vs adjacency lists vs and adjacency**

As evident from above code, an edge is created from src to dest in the adjacency list in a digraph and if the graph is undirected, we also need to create the edge from dest to src in the adjacency list....If the adjacency list is implemented by a linked list per node as usual, then removing such an edge changes to O(n) instead of O(log n). So, it depends. â€“ jonaprieto Sep 23 '18 at 14:17 add a comment

- 25/08/2014Â Â· In this blog post I will describe how to form the adjacency matrix and adjacency list representation if a list of all edges is given. 1. Edge list as two arrays Suppose we are given the graph below: The graph with n=5 nodes has the following edges: We can store the edges in two arraysâ€¦
- It can be represented in a 2-D array (matrix) or as an array of bags containing each edge (list). The data structure chosen largely depends on the size and density of the graph. The data structure chosen largely depends on the size and density of the graph.
- Adjacency List (AL) is an array of V lists, one for each vertex (usually in increasing vertex number) where for each vertex i, AL[i] stores the list of i's neighbors. For weighted graphs, we can store pairs of (neighbor vertex number, weight of this edge) instead.
- An adjacency list represents a graph as an array of linked list. The index of the array represents a vertex and each element in its linked list represents the other vertices that form an edge with the vertex.
