Real-time simulation

Definition

Real-time simulation refers to a computational method that allows for the modeling and analysis of dynamic systems as they occur, with minimal delay between the system's behavior and the simulation's output. This technique is vital in creating responsive environments where interactions can happen in real-time, making it essential for applications like robotics, gaming, and training systems. By processing data continuously, real-time simulations help users visualize changes and predict outcomes as they happen, enhancing decision-making and experimentation.
