Monte Carlo simulations are methods for simulating statistical systems Theaim is to generate a representative ensemble of con gurations to access ther-modynamical quantities without the need to solve the system analyticallyor to perform an exact enumeration The main principles of Monte Carlosimulations are ergodicity and detailed balance

Introduction to Monte Carlo Methods

In our Monte Carlo methods we just required that we sample from our space uniformly but this isn’t always easy to do MCMC gives us a way to sample from a desired pre{de ned distribution by forming a related Markov chain (or walk) over our state space with transition probabilities

What are the characteristics of Monte Carlo methods?

The de?ning characteristic of Monte Carlo methods is its use of random numbers in its simulations. In fact, these meth- ods derive their collective name from the fact that Monte Carlo, the capital of Monaco, has many casinos and casino roulette wheels are a good example of a random number generator.

How do we reduce the variance of Monte-Carlo estimators?

In particular, we describe control variates, antithetic variates and conditional Monte-Carlo, all of which are designed to reduce the variance of our Monte-Carlo estimators. We will defer a discussion of other variance reduction techniques such as common random numbers, stratifed sampling and importance sampling until later. 1 Simulation Eciency
