OCamlgraph is a graph library for Ocaml. Its contribution is three-fold:
1. It provides an easy-to-use graph implementation together with several
operations and algorithms over graphs, in Graph.Pack.Digraph.
It is a reasonably efficient imperative data structure for directed graphs
with vertices and edges labeled with integers.
Have a look at this module first in order to get an overview of what
this library provides. See also `demo.ml'.
2. 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.
See interface Sig for the graph signatures and modules Persistent and
Imperative for the implementations.
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.
3. 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.
How to link with OCamlgraph
---------------------------
OCamlgraph is packaged as a single module `Graph'. Link is done as follows:
- bytecode
ocamlc graph.cma <other files>
- native code
ocamlopt graph.cmxa <other files>
Examples
--------
You'll find examples of OCamlgraph use in demo.ml, demo_planar.ml and color.ml
(you can compile these programs with "make demo.opt", "make demo_planar.opt"
and "make color.opt" respectively).
