+# libsemigroups
+
+[libsemigroups](https://libsemigroups.readthedocs.io/) is a C++14 library
+containing implementations of several algorithms for computing finite, and
+finitely presented, semigroups and monoids. Namely:
+
+- the [Froidure-Pin algorithm](https://www.irif.fr/~jep/PDF/Rio.pdf) for
+  computing finite semigroups;
+- the [Todd-Coxeter algorithm](https://en.wikipedia.org/wiki/Todd%E2%80%93Coxeter_algorithm)
+  for finitely presented semigroups and monoids; see also
+  [this paper](https://arxiv.org/abs/2203.11148);
+- the [Knuth-Bendix algorithm](https://en.wikipedia.org/wiki/Knuth%E2%80%93Bendix_completion_algorithm)
+  for finitely presented semigroups and monoids;
+- the [Schreier-Sims algorithm](https://en.wikipedia.org/wiki/Schreier%E2%80%93Sims_algorithm)
+  for permutation groups;
+- a preliminary implementation of the
+  [Konieczny](https://link.springer.com/article/10.1007/BF02573672) and
+  [Lallement-McFadden](https://www.sciencedirect.com/science/article/pii/S0747717108800570)
+  algorithm for computing finite semigroups which act on sets;
+- an implementation of the
+  [Radoszewski-Rytter](https://link.springer.com/chapter/10.1007/978-3-642-11266-9_55)
+  algorithm for testing equivalence of words in free bands.
+- an implementation of the algorithm for solving the word problem
+  for small overlap monoids, and for computing normal forms in such monoids;
+  see [Kambites](https://doi.org/10.1016/j.jalgebra.2008.09.038),
+  [Kambites](https://doi.org/10.1016/j.jalgebra.2008.12.028), and
+  [Mitchell-Tsalakou](http://arxiv.org/abs/2105.12125).
+
+Libsemigroups is partly based on
+["Algorithms for computing finite semigroups"](https://www.irif.fr/~jep/PDF/Rio.pdf),
+["Expository Slides"](https://www.irif.fr/~jep/PDF/Exposes/StAndrews.pdf), and
+[Semigroupe 2.01](https://www.irif.fr/~jep/Logiciels/Semigroupe2.0/semigroupe2.html)
+by [Jean-Eric Pin](https://www.irif.fr/~jep/).
+
+Libsemigroups is used in the
+[Semigroups package](https://semigroups.github.io/Semigroups/) for
+[GAP](https://www.gap-system.org/), and it is possible to use libsemigroups
+directly in Python 3 via the package `libsemigroups_pybind11`.  The development
+version of libsemigroups is available on
+[github](https://github.com/libsemigroups/libsemigroups), and some related
+projects are [here](https://github.com/libsemigroups).
+
+The main classes in libsemigroups are named after the algorithms they
+implement; see, for example, `libsemigroups::FroidurePin`,
+`libsemigroups::Konieczny`, `libsemigroups::congruence::ToddCoxeter`,
+`libsemigroups::fpsemigroup::Kambites`,
+`libsemigroups::fpsemigroup::KnuthBendix`, and `libsemigroups::SchreierSims`.
+
+The implementations in `libsemigroups::FroidurePin`,
+`libsemigroups::Konieczny`, and `libsemigroups::SchreierSims` are generic and
+easily adapted to user-defined types.
+
+Libsemigroups uses: [HPCombi](https://github.com/hivert/HPCombi) which uses
+the SSE and AVX instruction sets for very fast manipulation of
+transformations, partial permutations, permutations, and boolean matrices of
+small size; [catch](https://github.com/catchorg/Catch2) for tests;
+[fmt](https://github.com/fmtlib/fmt) for reporting; and
+[eigen](http://eigen.tuxfamily.org/) for some linear algebra computations.
