Computer simulations

Definition

Computer simulations are digital representations of real-world processes or systems that use mathematical models to mimic the behavior of those systems over time. They allow researchers and engineers to predict outcomes, analyze complex interactions, and visualize scenarios that may be difficult or impossible to replicate in reality. By using computer simulations, adaptive optics for lasers can be optimized by modeling how light behaves as it passes through different media and encounters various distortions.
