maetl / subgraph.rb

Created June 10, 2017 13:22

Subgraph isomorphism matching for small in-memory Ruby graphs.

	$LOAD_PATH << "./lib"
	require 'mementus'

	# Prototype of subgraph isomorphism search using Ullmann’s original 1976
	# algorithm [1] as the foundation for a depth-first scan that moves forward
	# through each possible outgoing edge, then attempts to confirm the match by
	# doing a reverse edge lookup, comparing the query to the target graph.
	#
	# This is known to be a NP-complete problem but despite being exponential in
	# theory, in practice it’s possible to achieve reasonable results by using
