Boids is a computer simulation model created by Craig Reynolds in 1986 to mimic the flocking behavior of birds. The model uses simple rules to simulate how individual agents, or "boids," interact with one another, resulting in complex group behaviors. Each boid follows three primary rules: separation, alignment, and cohesion, which help them avoid collisions, match the direction of nearby boids, and stay close to the group. The Boids model has applications in various fields, including computer graphics, robotics, and artificial intelligence. It provides insights into collective behavior and can be used to simulate other natural phenomena, such as fish schooling or insect swarming.
