How to identify whether there exists a path between two nodes in an undirected graph
View path_exists.py
"""
Author: Eric J. Ma
Affiliation: Massachusetts Institute of Technology.
Purpose of Code:
This code was written because I did not find a sufficiently-concise way of identifying whether
two nodes were connected by some path. Bidirectional Djikstra as implemented in NetworkX returns
False is not connected, but (length, path) if connected; I wanted a pure "True/False"
implementation.
