How To Install libocamlgraph-ocaml-dev on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libocamlgraph-ocaml-dev on Ubuntu 18.04.
What is libocamlgraph-ocaml-dev
libocamlgraph-ocaml-dev is:
Ocamlgraph is a graph library for OCaml. Its contribution is three-fold:
It provides an easy-to-use graph data structure together with several operations and algorithms over graphs. It is a reasonably efficient imperative data structure for directed graphs with vertices and edges labeled with integers.
Then ocamlgraph provides several other graph implementations for those not satisfied with the one above. Some are persistent (imutable) and other imperative (mutable). Some are directed and other are not. Some have labels for vertices, or labels for edges, or both. Some have abstract types for vertices. etc. These implementations are written as functors: you give the types of vertices labels, edge labels, etc. and you get the data structure as a result.
Finally, ocamlgraph provides several classic operations and algorithms over graphs. They are also written as functors i.e. independently of the data structure for graphs. One consequence is that you can define your own data structure for graphs and yet re-use all the algorithms from this library – you only need to provide a few operations such as iterating over all vertices, over the successors of a vertex, etc.
