General question about nearest neighbor data structures

I want to improve the speed of my feature matching algorithm. The matching is based on comparing feature A with circularly shifted feature B. The shifting is pe

Currently able to calculate total neighbors, I need just the neighbors that are alive

I have a bool [,] board that stores if the cell is alive or dead. The code I have provided is correctly telling me the total neighbors for each cell, the proble

Problem statement: I have 150k points in a 3D space with their coordinates stored in a matrix with dimension [150k, 3] in mm. I want to find all the neighbors o
