There is a joke that makes me laugh a lot:
“Did you know that before the clock was invented, people had to actively walk around and ask people the time?”
Obviously there is no need to explain the joke, but if we think about it a bit (as good mathematicians do) we can say that the joke is about the fact that the information of a particle of a group It can be used to inform all other particles. This concept is much deeper than the joke I just told and can be exploited further.
Let us consider a self-organizing system, such as a flock of birds or a school of fish. We can define such a system as one made up of Particles (for example, a particle is a bird). We can also assume with a good degree of approximation that these particles move in space by adjusting their positions based on two factors:
- The best position that The specific particle knows: what the bird thinks is best for itself.
- He global The best position given by all the particles that “communicate” with each other: what the “main bird” orders the bird to do.
