In this Library it implements a generic Interface `IGraph`
where `TEdge : IEdge { TVertex Source; TVertex Target; }` | +| (dense) | A __dense graph__ has up to \|Vertices\|² Edges | +| (sparse) | A __sparse graph__ fewer Edges than \|Vertices\| * Log(\|Vertices\|) | +| Vertex | __Vertices__ (AKA __Nodes__) are simple objects
which have names (Identity) and sometimes other properties.

In this Library Vertices can be any Type with an Identity Relation
implemented as `IComparable`. | +| Edge | An __edge__ is a (directed, i.e. ordered) connection
from the __Source__ Vertex to the __Target__ Vertex.

It is modeled as an `IEdge`
| +| (reverse) | The __reverse__ (AKA transpose) Edge runs in the opposite Direction
from the __Target__ Vertex to the __Source__ Vertex.
`ReversedBidirectionalGraph` wraps a Graph and exposes it by swapping `InEdges` and `OutEdges`. | +| (adjacent) | Union of `InEdges` and `OutEdges`. | +| (Properties) | Edges can also have Properties, mostly a `Length` or `Cost`.
The Edges impose a discrete Topology on the Graph. | +| Direction | - __Directed__ Graphs (AKA `Digraph`) consist of only directed Edges.
- The __reverse__ Graph consists of the same Vertices but __reversed Edges__.
- __Undirected__ Graphs can be modeled as the Union of a Graph and its Reverse,
i.e. all Edges can be be traversed | +| Path | A Path is a contiguous sequence of Edges,
i.e. the __Target__ Vertex of the previous Edge is the __Source__ Vertex of the next Edge. | +| (simple) | A simple path is a path in which no vertex is repeated.
| +| Cycle | A Cycle is a simple path, except the first and last Nodes are the same.
| +| Component | A connected Component of a Graph is a Sub-Graph
with a path from every node to every other node in the Component | +| Tree | A graph with no cycles is called a tree.
Prove by induction that a tree on V vertices has exactly V - 1 edges. | +| Diamond | A Diamond is | +| Forest | A group of disconnected trees is called a forest. | +| Spanning Tree | A spanning tree of a Component is a sub-graph that
contains all the vertices but only enough of the edges to form a tree. | + +## Examples + +### Geographical Navigation + +- The Vertices are geographical Places and +- the Edge Length is usually the 'Distance' between these Places. + +### Electrical Wiring + +- The Vertices are electronic Components and +- the Edge Properties can often be neglected, + unless for high Frequencies or Currencies + where Impedance, Capacity and Resistance become relevant. + +### Finite State-Machines + +Graphs can be used to visualize finite State-Machines with +- the States as Vertices and +- the Transitions as Edges. + +## Visualization + +One can draw a graph by marking points for the vertices and +drawing lines connecting them for the edges. + +The Placement of the Vertices is usually arbitrary, +but it considerably reduces Confusion when Crossings of Edges are minimized. + +## Samples + +### Sample Vertices are named `a`,`b`,`c`,... + +### Sample Edges are just ordered Pairs of Vertices: `ab`, `ed`, ... + +### Paths are just Strings of Vertices `abfd`... + +### V = |Nodes| = Number of Vertices + +### E = |Edges| = Number of Edges + +## Data Structures + +There are two primary ways to efficiently represent Graphs in Programs. +The choice between them determines Storage and Efficiency of Algorithms. +For most efficient Representation the Vertices are 'numbered', +which can be achieved by storing the Vertices in a List +and storing the Position in an `Index` Property of each Vertex. + +### Adjacency Matrix for dense Graphs + +Modelled by a 2D Array of `float` or `bool` Values +representing the Length or (reciprocal) Cost of the Connection. +The 2 Indices of the Array are determined from the `Index` Property of each Vertex + +This is very efficient both in Access in O(1) and Storage, but only for dense Graphs. +For large Graphs the O(V²) Storage becomes a Problem. + +### Adjacency List for sparse Graphs + +This is the preferred solution for sparse Graphs, even large ones. +It is modelled by a jagged, compressed 2D Array of Vertices or Vertex Indices. +This requires O(E) Storage, but Access is typically O(V Log V). +The first Index is determined from the `Index` Property of the `Source` Vertex. +The second Index is usually determined by BiSection of a sorted List or by a Hash-Table. + + +### Additional Node Information + +Extra information associated with each vertex can be accommodated +by using auxiliary arrays indexed by vertex number +(or by making adj an array of records in the adjacency structure representation). +Extra information associated with each edge can be put in the adjacency list nodes +(or in an array a of records in the adjacency matrix representation), +or in auxiliary arrays indexed by edge number (this requires numbering the edges). + + +## Algorithms + + +### Eulerian_Trail + + +In graph theory, an Eulerian __trail__ (or **Eulerian path**) is a trail in a finite graph +that visits __every Edge exactly once__ (allowing for revisiting vertices). + +Similarly, an Eulerian __circuit__ or Eulerian __cycle__ is an Eulerian trail +that __starts and ends on the same vertex__. + +> They were first discussed by Leonhard Euler +> while solving the famous [[#Königsberg Problem]] in 1736. +> +> The problem can be stated mathematically like this: +> Given the graph in the image, is it possible to construct a path +> (or even a cycle; i.e., a path starting and ending on the same vertex) +> that visits each edge exactly once? +> +> Euler proved that a __necessary condition__ for the existence of Eulerian circuits is +> that __all vertices in the graph have an even degree__, +> and stated without proof that connected graphs with all vertices of even degree +> have an Eulerian circuit. +> +> The first complete proof of this latter claim was published +> posthumously in 1873 by Carl Hierholzer.
