%description
Libsemigroups is a C++ library for semigroups and monoids; it is partly
based on "Algorithms for computing finite semigroups", "Expository
Slides", and Semigroupe 2.01 by Jean-Eric Pin.

The libsemigroups library is used in the Semigroups package for GAP.

Some of the features of Semigroupe 2.01 are not yet implemented in
libsemigroups; this is a work in progress.  Missing features include
those for:

- Green's relations, or classes
- finding a zero
- minimal ideal, principal left/right ideals, or indeed any ideals
- inverses
- local submonoids
- the kernel
- variety tests.
These will be included in a future version.

Libsemigroups performs roughly the same as Semigroupe 2.01 when there is
a known upper bound on the size of the semigroup being enumerated, and
this is used to initialize the data structures for the semigroup; see
libsemigroups::Semigroup::reserve for more details.  Note that in
Semigroupe 2.01 it is always necessary to provide such an upper bound,
but in libsemigroups it is not.

Libsemigroups also has some advantages over Semigroupe 2.01:
- there is a (hopefully) convenient C++ API, which makes it relatively
  easy to create and manipulate semigroups and monoids
- there are some multithreaded methods for semigroups and their
  congruences
- you do not have to know/guess the size of a semigroup or monoid before
  you begin
- libsemigroups supports more types of elements than Semigroupe 2.01
- it is relatively straightforward to add support for further types of
  elements and semigroups
- it is possible to enumerate a certain number of elements of a
  semigroup or monoid (say if you are looking for an element with a
  particular property), to stop, and then to start the enumeration again
  at a later point
- you can instantiate as many semigroups and monoids as you can fit in
  memory
- it is possible to add more generators after a semigroup or monoid has
  been constructed, without losing or having to recompute any
  information that was previously known
- libsemigroups contains rudimentary implementations of the Todd-Coxeter
  and Knuth-Bendix algorithms for finitely presented semigroups, which
  can also be used to compute congruences of a (not necessarily finitely
  presented) semigroup or monoid.
