<longdescription lang="en">
libsemigroups is a C++14 library containing implementations of
several algorithms for computing finite, and finitely presented,
semigroups and monoids. Namely:
* the Froidure-Pin algorithm for computing finite semigroups;
* the Todd-Coxeter algorithm for finitely presented semigroups
and monoids;
* the Knuth-Bendix algorithm for finitely presented semigroups
and monoids;
* the Schreier-Sims algorithm for permutation groups;
* a preliminary implementation of the Konieczny and Lallement-
McFadden algorithm for computing finite semigroups which act
on sets;
* an implementation of the Radoszewski-Rytter 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;
* a version of Sims low index subgroup algorithm for computing
one-sided congruences of a semigroup or monoid;
* a version of Stephen's procedure for finitely presented
semigroups and monoids (for a given word w this procedure
is for determining words equivalent to w or that are left
divisors of w).
