Models — Arborescence Graph Library

Arborescence.Models version

This package provides a basic implementation for Graph and Forward Incidence concepts.

        ┌   tail : E → V?
Graph   ┤
        └   head : E → V?       ┐
                                ├   Forward Incidence
            out-edges : V → [E] ┘

SimpleIncidenceGraph represents a directed multigraph (permitting loops) with edges not having their own identity [1].
IndexedIncidenceGraph represents a directed multigraph (permitting loops) with edges having their own identity [2].
MutableUndirectedSimpleIncidenceGraph and MutableUndirectedIndexedIncidenceGraph provide their mutable undirected counterparts.

Vertices are represented as integers and must fill the range [0..VertexCount).
Edges are stored as incidence lists in contiguous spans.

Basic usage

Let's consider this simple graph:

       ┌──>──┐
(0)   (1)─>─(2)─>─(3)┐
       └──<──┘     └<┘

This is how to recreate it in the code:

SimpleIncidenceGraph.Builder builder = new();
builder.Add(1, 2);
builder.Add(1, 2);
builder.Add(2, 1);
builder.Add(2, 3);
builder.Add(3, 3);
SimpleIncidenceGraph graph = builder.ToGraph();
Console.WriteLine(graph.VertexCount);

The expected output is 4 — including vertex 0 even if it was not mentioned while creating the graph. Vertex count is determined as one plus the max id of the vertices, so they fill the range [0..VertexCount).

Now let's explore the edges incident to vertex 2:

const int vertex = 2;
var edgeEnumerator = graph.EnumerateOutEdges(vertex);
while (edgeEnumerator.MoveNext())
{
    Endpoints edge = edgeEnumerator.Current;
    Debug.Assert(graph.TryGetTail(edge, out int tail) &&
        tail == vertex);
    if (graph.TryGetHead(edge, out int head))
        Console.WriteLine(head);
}

The expected output — all the neighbors of vertex 2:

1
3
