Traversal — Arborescence Graph Library

Arborescence.Traversal version

This package provides basic traversal algorithms for incidence and adjacency graphs:

  • generic search taking a frontier as a parameter,
  • breadth-first search (BFS), which is a special case of generic search with FIFO-queue as the frontier,
  • depth-first search (DFS), which is not a special case of generic search with LIFO-stack as the frontier [1].

Basic usage

Let's consider this implicit adjacency graph [2]:

public readonly record struct Node(int Value);

public sealed class AdjacencyGraph : IAdjacency<Node, IEnumerator<Node>>
    public IEnumerator<Node> EnumerateNeighbors(Node vertex) =>
        vertex.Value is < 0 or >= 10
            ? Enumerable.Empty<Node>().GetEnumerator()
            : EnumerateNeighborsIterator(vertex);

    private static IEnumerator<Node> EnumerateNeighborsIterator(
        Node vertex)
        yield return new(vertex.Value >> 1);
        yield return new(vertex.Value << 1);

This is how to traverse it in a breadth-first manner with an adjacency version of the algorithm:

AdjacencyGraph adjacencyGraph = new();
Node source = new(3);
IEnumerator<Node> vertexEnumerator =
    EnumerableBfs<Node>.EnumerateVertices(adjacencyGraph, source);
while (vertexEnumerator.MoveNext())
