Monte Carlo Simulations

Definition

Monte Carlo simulations are computational algorithms that use random sampling to estimate complex mathematical or statistical outcomes. These simulations are particularly useful in scenarios where deterministic solutions are difficult or impossible to derive, allowing for a range of possible outcomes and their probabilities to be modeled. In the context of autonomous systems, these simulations help in analyzing uncertainties in motion detection, collision avoidance, and ensuring the reliability of certification processes.
