Barnes-Hut Algorithm

The Barnes-Hut algorithm is a method used to efficiently simulate how many particles interact through forces like gravity. Instead of calculating every pair’s interaction, it groups distant particles into clusters based on their positions. It then treats these groups as single combined entities when calculating forces on a particular particle, significantly reducing computation time. This approach allows simulations involving thousands or millions of particles to run faster while still maintaining accurate results, making it valuable in physics and astronomy for modeling large systems like galaxies or particle distributions.
