A Go implementation of the Adjacency Descriptive Integer Graph data structure. The data structure uses Integers to Describe the set of nodes Adjacent to a given node in a graph.
Graphs are used throughout computer science to store and relate data. A good example is a Social Graph.
Two of the most common ways to implement a graph are the Adjacency List and the Adjacency Matrix. Adjacency Lists are compact, but handling them often requires linear traversal of linked-lists. Adjacency Matrices are easy to reason about and parallelizable, but often take up far too much space.
The Adjacency Descriptive Integer is an attempt to represent a graph in a compactly, while still allowing for simple reasoning about node connections and parallel operations.
ADI Graphs are a more specific implementation of a bitset graph representation, aiming to exploit the speed of processing register-size operations on 8-, 16-, 32-, and 64- bit machines.
