Monte Carlo simulation has become an essential tool in the pric-ing of derivative securities and in riskThis can be useful in focusing variance reduction techniques on important features of Brownian paths. Variance reduction techniques devel-oped for application to photon transport are, i n principle, also applicable to electrons, but in general the simulations doAs pointed out by Raeside (1976), nuclear medicine is the area where most of the early Monte Carlo calculations in the field were performed. Dealing with all aspects of Monte Carlo simulation of complex physical systems encountered in condensed-matter physics and statistical mechanics, this book provides an introduction to computer simulations in physics.

The Monte Carlo Simulation of Radiation Transport p.6/35.Techniques that speed up MC simulations without introducing a systematic error in the result are known as variance reduction techniques (VRT). The last decade has seen the development of numerous variance reduction techniques (VRTs) (Liu et alBadal, A. and Badano, A. (2009). Monte Carlo simulation of X-ray imaging us-ing a graphics processing unit.Monte Carlo Calculations in Nuclear Medicine. Institute of Physics Publishing. In Monte Carlo simulation, instead of collecting the iid data X1, . . . , Xn, we simulate it.Thus by choosing any C for. which X,C 0 we can always reduce variance, and it is desirable to choose a C that is strongly. The application of Variance Reduction Techniques (VRT) in Monte Carlo (MC) codes brings significant improvement in efficiency and a significant profit in the time of simulation.
