From Idea to Follow with Particle Swarm Optimization, Utilizing Python | by Piero Paialunga | Sep, 2024

There’s a joke that cracks me up:

“Do you know that, earlier than the clock was invented, folks needed to actively roam round and ask folks the time?”

There’s clearly no want to elucidate the joke, but when we had been to overthink it a bit bit (like good mathematicians do) we will say that the joke is about the truth that the knowledge of a particle of a bunch can be utilized to tell all the opposite particles. This idea is definitely means deeper than the joke I simply mentioned and might be exploited additional.

Let’s think about a self-organized system, equivalent to chook flocking or fish education. We are able to outline this method as one manufactured from particles (e.g. a particle is a chook). We are able to additionally assume with a superb diploma of approximation that these particles transfer round in house adjusting their positions based mostly on two components:

• The very best place that the particular particle is aware of: what the chook thinks is greatest for themselves.
• The international greatest place that’s given by all of the particles “speaking” with one another: what the chook is instructed to do by the “major chook”
