Simulation

Definition

Simulation refers to the process of creating a virtual representation of a real-world system or process in order to study its behavior under various conditions. It allows for experimentation and analysis without the risks and costs associated with physical trials, making it particularly useful in fields like underwater robotics where testing in actual environments can be challenging. Through simulations, engineers can fine-tune their designs and control algorithms to enhance performance and reliability.
