ELI5: Explain Like I'm 5

Crowd simulation

Crowd simulation is when people or objects are programmed to move in a group. Let's pretend that we are organizing a party for our stuffed animals. We have to figure out how our stuffed animals will move around the room and interact with each other. This is a lot like how a computer program simulates how people might move in a crowded area like a concert, parade, or even a busy street corner.

To simulate a crowd, we need to create a group of people or objects that will move together. Each person or object is given a set of rules to follow that determine how they move. For example, if there is a wall in the way, the people in the crowd will go around it.

The computer program can use different algorithms to simulate the crowd. An algorithm is like a set of instructions that tells the computer what to do. Some algorithms might make the people move in random patterns, while others might make them move in a more structured, organized way. This kind of technology is used in movies, video games, and even in real life when planners need to figure out how to get people out of a building in a safe and efficient way.

Overall, it's like we are creating a pretend group of people or objects that need to move around and interact. We make sure that they can all move around without bumping into each other, and follow the rules we set out for them.
