The Quasi-Monte Carlo method recently became popular in the area of mathematical finance or computational finance. [1] In these areas, high-dimensional numerical integrals, where the integral should be evaluated within a threshold ε, occur frequently. Hence, the Monte Carlo method and the quasi-Monte Carlo method are beneficial in these ...
An example of distribution with 500 LDS points is given in Figure 2. Figure 2. 500 low discrepancy points. Numerous LDS have been created named after their inventors, for example: Halton, Hammersley, Sobol, Faure, Niederreiter. Generally, the quasi-Monte Carlo (QMC) method is defined by
Markov chain quasi-Monte Carlo methods [18] [19] such as the Array–RQMC method combine randomized quasi–Monte Carlo and Markov chain simulation by simulating chains simultaneously in a way that better approximates the true distribution of the chain than with ordinary MCMC. [20]
A Monte Carlo simulation shows a large number and variety of possible outcomes, including the least likely as well … Continue reading → The post Understanding How the Monte Carlo Method Works ...
A similar approach, the quasi-Monte Carlo method, uses low-discrepancy sequences. These sequences "fill" the area better and sample the most important points more frequently, so quasi-Monte Carlo methods can often converge on the integral more quickly.

To calculate the indices using the (quasi) Monte Carlo method, the following steps are used: [1] [2] Generate an N×2d sample matrix, i.e. each row is a sample point in the hyperspace of 2d dimensions. This should be done with respect to the probability distributions of the input variables.
and quasi random variables (in Quasi-Monte Carlo method) For simulation with black-box models subset simulation and line sampling can also be used. Under these headings are a variety of specialized techniques; for example, particle transport simulations make extensive use of "weight windows" and "splitting/Russian roulette" techniques, which ...
