  2. Monte Carlo method - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_method

    Monte Carlo simulation: Drawing a large number of pseudo-random uniform variables from the interval [0,1] at one time, or once at many different times, and assigning values less than or equal to 0.50 as heads and greater than 0.50 as tails, is a Monte Carlo simulation of the behavior of repeatedly tossing a coin.

  3. Simulation hypothesis - Wikipedia

    en.wikipedia.org/wiki/Simulation_hypothesis

    The simulation hypothesis proposes that what one experiences as the world is actually a simulated reality, such as a computer simulation in which we ourselves are constructs. [1] [2] There has been much debate over this topic in the philosophical discourse, and regarding practical applications in computing.

  4. Probability theory - Wikipedia

    en.wikipedia.org/wiki/Probability_theory

    Probability theory or probability calculus is the branch of mathematics concerned with probability. Although there are several different probability interpretations , probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms .

  5. Simulated annealing - Wikipedia

    en.wikipedia.org/wiki/Simulated_annealing

    The simulation can be performed either by a solution of kinetic equations for probability density functions, [7] [8] or by using a stochastic sampling method. [6] [9] The method is an adaptation of the Metropolis–Hastings algorithm, a Monte Carlo method to generate sample states of a thermodynamic system, published by N. Metropolis et al. in ...

  6. Stochastic simulation - Wikipedia

    en.wikipedia.org/wiki/Stochastic_simulation

    A stochastic simulation is a simulation of a system that has variables that can change stochastically (randomly) with individual probabilities. [ 1 ] Realizations of these random variables are generated and inserted into a model of the system.

  7. Rejection sampling - Wikipedia

    en.wikipedia.org/wiki/Rejection_sampling

    In numerical analysis and computational statistics, rejection sampling is a basic technique used to generate observations from a distribution.It is also commonly called the acceptance-rejection method or "accept-reject algorithm" and is a type of exact simulation method.

  8. Subset simulation - Wikipedia

    en.wikipedia.org/wiki/Subset_simulation

    Subset simulation [1] is a method used in reliability engineering to compute small (i.e., rare event) failure probabilities encountered in engineering systems. The basic idea is to express a small failure probability as a product of larger conditional probabilities by introducing intermediate failure events.

  9. Uncertainty quantification - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_quantification

    Simulation-based methods: Monte Carlo simulations, importance sampling, adaptive sampling, etc. General surrogate-based methods: In a non-instrusive approach, a surrogate model is learnt in order to replace the experiment or the simulation with a cheap and fast approximation. Surrogate-based methods can also be employed in a fully Bayesian fashion.
