Babai's Nearest Plane Algorithm is a method used for solving the nearest lattice point problem by projecting a point onto a lattice using hyperplanes. This algorithm helps in efficiently finding the closest lattice point to a given point in a multi-dimensional space, which is crucial in applications like lattice-based codes. By leveraging the geometry of lattices, the algorithm effectively narrows down the search space, leading to better performance in coding theory and cryptography.
