On approximating the covering radius and finding dense lattice subspaces

D Dadush - Proceedings of the 51st Annual ACM SIGACT …, 2019 - dl.acm.org
In this work, we give a novel algorithm for computing dense lattice subspaces, a
conjecturally tight characterization of the lattice covering radius, and provide a bound on the …

The subspace flatness conjecture and faster integer programming

In a seminal paper, Kannan and Lovász (1988) considered a quantity KL(Λ,K) which
denotes the best volume-based lower bound on the covering radius μ(Λ,K) of a convex body …

Towards strong reverse Minkowski-type inequalities for lattices

D Dadush, O Regev - 2016 IEEE 57th Annual Symposium on …, 2016 - ieeexplore.ieee.org
We present a natural reverse Minkowski-type inequality for lattices, which gives upper
bounds on the number of lattice points in a Euclidean ball in terms of sublattice …

[PDF][PDF] Hardness of the covering radius problem on lattices

I Haviv, O Regev - Chicago Journal of Theoretical Computer …, 2012 - cjtcs.cs.uchicago.edu
We provide the first hardness result for the Covering Radius Problem on lattices (CRP).
Namely, we show that for any large enough p≤∞ there exists a constant cp> 1 such that …

Dual vectors and lower bounds for the nearest lattice point problem

J Hastad - Combinatorica, 1988 - Springer
We prove that given a point\overline z outside a given lattice L then there is a dual vector
which gives a fairly good estimate for how far from the lattice the vector is. To be more …

Finding a shortest vector in a two-dimensional lattice modulo m

G Rote - Theoretical Computer Science, 1997 - Elsevier
We find the shortest non-zero vector in the lattice of all integer multiples of the vector (a, b)
modulo m, for given integers 0< a, b< m. We reduce the problem to the computation of a …
