WebJul 25, 2024 · The Lenstra–Lenstra–Lovász (LLL) algorithm is an algorithm that efficiently transforms a “bad” basis for a lattice L into a “pretty good” basis for the same lattice. This transformation of a bad basis into a better basis is known as lattice reduction, and it has useful applications.
