Introduction taken from the BGL introduction page. We believe that the main contribution of the BGL is the formulation of this interface." BGL provides some general purpose graph classes that conform to this interface, but they are not meant to be the "only" graph classes there certainly will be other graph classes better for certain situations. This is an "open" interface in the sense that any graph library that implements this interface will be interoperable with the BGL generic algorithms and with other algorithms that also use this interface. Part of the Boost Graph Library is an interface for how the structure of a graph can be accessed using a generic interface that hides the details of the graph data structure implementation. A standardized generic interface for traversing graphs is of utmost importance to encourage reuse of graph algorithms and data structures. Consequently, these abstractions must also be represented in computer programs.
The BoostGraphLibrary is a C++ generic graph library that introduces itself as such: "Graphs are mathematical abstractions that are useful for solving many types of problems in computer science. This section discusses aspects about the porting from C++ to C# of the BoostGraphLibrary. indegree(v) denotes the number of incoming edges of v and outdegree(u), the number of outgoing edges of u. If e=(u,v), then e is an outgoing edge of u and an incoming edge of v. This is a quick remainder about graph theory:Ī directed graph G=(V圎) consists of a finite set V=V(G) of vertices and a finite multi-set E contained in VxV = of edges that are ordered pair of vertices.

The library provides the basic data structure to represent vertices, edges and graphs, and also provides generic implementation of various graph algorithms such as the depth-first-search, the Dijkstra shortest path, etc.Īs the library comes with a full NDoc reference manual, this article will not enter into deep coding details. Graph problems arise in a number of situations (more often than you would think): file compilation order, network band-with, shortest path, etc. This library is an attempt to port the Boost Graph Library (BGL) from C++ to C#. This article presents a Generic Graph Library, 100% C#. There have been a lot of changes to the source code and the article below, since the first submission on December 8 th, 2020.

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages PDF or Postscript for inclusion in other documents or display in an interactive graph browser.
Graphviz edge length software#
It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Graphviz is open source graph visualization software.
