Monte-Carlo methods

Monte-Carlo methods are very powerful, but computationally expensive methods with a high potential for parallelization, which allows to calculate of very complex problems, which do not have analytical or other solutions.

Pros and Cons of the Monte-Carlo technique

Pros of Monte Carlo Methods:

Versatility: Monte Carlo methods are versatile and can be applied to a wide range of problems in various fields such as finance, physics, engineering, and more.

Complex Problems: Effective for solving problems with high complexity and a large number of variables or dimensions where analytical solutions may be difficult or impossible to obtain.

Randomness: Incorporates randomness and probabilistic sampling, making it suitable for simulating stochastic processes and modelling uncertainty.

Approximation: Provides a way to approximate solutions to problems, especially when closed-form solutions are not available.

Parallelization: Monte Carlo simulations are often parallelizable, allowing for efficient use of computational resources.

Cons of Monte Carlo Methods:

Computational Intensity: Monte Carlo simulations can be computationally expensive, especially when a large number of random samples is required for accurate results.

Convergence Rates: The rate of convergence to the true solution may be slow, and the accuracy of the results depends on the number of samples used.

Not Always Efficient: In some cases, alternative methods or analytical solutions may exist that are more computationally efficient.

Variance: The results can have high variance, especially when dealing with rare events, and additional techniques may be needed to reduce variance.

Sampling Bias: The quality of results heavily relies on the quality of random sampling, and biased sampling can lead to inaccurate conclusions.
