{{draft task}}
A [[wp:Boids|Boids]] algorithm simulates the flocking behaviourbehavior of birds. This task requires the creation of a graphical or purely textual simulation of a flock of birds navigating the cave with obstacles depicted below.

If you implement a purely textual simulation, this is a possible board representation, where "O" are the boids that should go toward the right, "#" are fixed walls that should be avoided by the boids, and "." is free space (using a space is also acceptable for free space, if you add some kind of frame around the board).
Line 23 ⟶ 25:
A simulation that doesn't contain obstacles but only shows flocking behavior is acceptable.
