KnuthBendixCongruenceByPairs(congruence_type, KnuthBendix const&)ΒΆ

libsemigroups::KnuthBendixCongruenceByPairs::KnuthBendixCongruenceByPairs(congruence_type type, KnuthBendix const &kb)

Construct a KnuthBendixCongruenceByPairs over the fpsemigroup::KnuthBendix instance kb representing a left/right/2-sided congruence according to type.

Exceptions

This function is noexcept and is guaranteed never to throw.

Complexity

Constant.

Warning

The parameter kb is copied, this might be expensive, use a std::shared_ptr to avoid the copy!

Parameters

  • type: whether the congruence is left, right, or 2-sided

  • kb: a reference to the semigroup over which the congruence is defined.
