Lenstra-Lenstra-Lovasz algorithm

A lattice reduction algorithm, named after discoverers Lenstra, Lenstra, and Lovasz, that produces a lattice basis of "short" vectors. It was noticed by Lenstra et al. (1982) that the algorithm could be used to obtain factors of univariate polynomials, which amounts to the determination of integer relations. However, this application of the algorithm, which later came to be one of its primary applications, was not stressed in the original paper. For a complexity analysis of the LLL algorithm, see Storjohann.
