In this article, we will be tackling the fixed radius nearest neighbor problem, this is a variation on a nearest neighbor search. Generally, we can state the problem as such: Given an input set of points in d-dimensional Euclidean space and a fixed distance Δ. Design a data structure that given a query point q, find the points of the data structure that are within distance Δ to point q.
