Python graphs library to perform BFS, DFS, Dijkstra, and more.

pygraphs

Description

pygraphs provides tools to perform BFS, DFS, Dijkstra, and more on graphs. The package support weighted graphs, directed graphs but not multigraphs.

Usage

This section will guide you through the basic usage of the pygraphs package. Several examples are available on the online documentation.

Construct a graph

To create a graph, you can provide the edges or the adjacency :

from pygraphs import Graph

graph = [[1, 2], [0, 2], [0, 1, 3], [2, 4], [3], [6], [5]]
undirected_graph = Graph.from_adjacency(graph)

Perform operations on graphs

Several algorithms are availables to perform basic operations on graphs. For example, the following compute the adjacency matrix by BFS:

from pygraphs import bfs_matrix

adjacency_matrix = bfs_matrix(undirected_graph)
print(f"adjacency_matrix (shape={len(adjacency_matrix)}x{len(adjacency_matrix[0])}):")
print(adjacency_matrix)

# Expected output:
# adjacency_matrix (shape=(7x7)):
# [[ 0  1  1  2  3 -1 -1]
#  [ 1  0  1  2  3 -1 -1]
#  [ 1  1  0  1  2 -1 -1]
#  [ 2  2  1  0  1 -1 -1]
#  [ 3  3  2  1  0 -1 -1]
#  [-1 -1 -1 -1 -1  0  1]
#  [-1 -1 -1 -1 -1  1  0]]
