This is a more optimised version (created by Kin Fai Franco Chan and Zakaria Achouri) of the original MATLAB zombie apocalypse group project (https://github.com/UoMLegends/Zombie). This version uses vectorisation for movement increment, uses knnsearch for finding nearest enemy and preallocation for memory efficiency.

To simplify things, we modelled our zombie apocalypse based on a few simple behaviours of both zombies and humans.
- If human and zombie are far away from each other, they simply move randomly (Brownian motion).
- If human and zombie are relatively close to each other, then the zombie would chase after the human, and the human would run away.
- If a zombie is close to multiple humans, then the zombie would chase after the closest human.
- If human and zombie are very close to each other, then they will fight. Sometimes the human wins the fight, which results in killing the zombie. And sometimes the zombie wins the fight, which results in turning the human into a zombie.
