Discret venimilation is building a virtual representation of the system using random numbers to play that virtual representation. It then collects some data about what just happened. Let me set the problem that you all laid out here. This is a bicycle repair shop, and there's a a set of gaits, or actions, or, i guess events, you might say, that it flows through. And by sampling random numbers, we can move virtual people around tor barber shop and look at what would happen. Am, just observe, collect data, crunch ty data.
