# Algebraic graphs
[](https://travis-ci.org/snowleopard/alga) [](https://ci.appveyor.com/project/snowleopard/alga)
A library for algebraic construction and manipulation of graphs in Haskell. See
[this paper](https://github.com/snowleopard/alga-paper) for the motivation behind the library, the underlying
theory and implementation details.
The following series of blog posts also describe the ideas behind the library:
* Introduction: https://blogs.ncl.ac.uk/andreymokhov/an-algebra-of-graphs/
* A few different flavours of the algebra: https://blogs.ncl.ac.uk/andreymokhov/graphs-a-la-carte/
