Models — Arborescence Graph Library

Arborescence.Models version

This package provides a generic implementation of graph interfaces and collection concepts.

ListAdjacencyGraph<TVertex, TVertexMultimap> implements an adjacency graph as a dictionary that maps from a vertex to a list of its out-neighbors of type List<TVertex>.
ListIncidenceGraph<TVertex, TEdge, TEndpointMap, TEdgeMultimap> implements an incidence graph as a dictionary that maps from a vertex to a list of its out-edges of type List<TEdge>.

Basic usage

For example, we have four airports (Omsk, London, Istanbul, Taipei) and five unspecified flights connecting them:

  ┌───>───┐       ┌─>─┐
[LHR]─>─[IST]─>─[TPE] │
  └───<───┘       └───┘

[OMS]

We can create an adjacency graph as follows:

Dictionary<string, List<string>> neighborsByVertex = new(4)
{
    ["OMS"] = new(),
    ["LHR"] = new() { "IST", "IST" },
    ["IST"] = new() { "LHR" }
    // Let's add "TPE" later.
};
var graph = ListAdjacencyGraph<string>.Create(neighborsByVertex);
graph.TryAddVertex("TPE");
graph.AddEdge("IST", "TPE");
graph.AddEdge("TPE", "TPE");

IncidenceEnumerator<string, List<string>.Enumerator> flightsFromIstanbul =
    graph.EnumerateOutEdges("IST");
while (flightsFromIstanbul.MoveNext())
    Console.WriteLine(flightsFromIstanbul.Current);

Expected output is:

[IST, LHR]
[IST, TPE]

Now let's look at the actual flights that connect these airports:

        BA676
  ┌───────>───────┐             EVA5288
  │     TK1980    │      TK24     ┌─>─┐
[LHR]─────>─────[IST]─────>─────[TPE] │
  └───────<───────┘               └───┘
        BA677

[OMS]

The following is one of the ways you can create an incident graph. (For clarity, we represent flights as integers rather than strings.)

var graph = ListIncidenceGraph<string, int>.Create();
_ = graph.TryAddVertex("OMS");
_ = graph.TryAddEdge(676, "LHR", "IST");
_ = graph.TryAddEdge(1980, "LHR", "IST");
_ = graph.TryAddEdge(677, "IST", "LHR");
_ = graph.TryAddEdge(24, "IST", "TPE");
_ = graph.TryAddEdge(5288, "TPE", "TPE");

List<int>.Enumerator flightsFromIstanbul =
    graph.EnumerateOutEdges("IST");
while (flightsFromIstanbul.MoveNext())
    Console.WriteLine(flightsFromIstanbul.Current);

Expected output is:

677
