Monte Carlo Method

Definition

The Monte Carlo Method is a statistical technique that uses random sampling to estimate mathematical functions and simulate the behavior of complex systems. It is widely used for solving problems in physics, finance, engineering, and many other fields, particularly when dealing with uncertainty and variability. This method helps in understanding vortex dynamics and Ginzburg-Landau simulations by allowing researchers to model different scenarios and visualize the probabilistic outcomes of various configurations.
