# Monte carlo simulation

Hello,
1. Does anybody know which book that gives a good explanation about monte carlo simulation?
But, many of them don't actually show, how to perform monte carlo simulation.

Questions
2. Is it actually the same as generating random numbers? Gaussian distribution?
so, it is actually random variables with normal distribution?

thanks

No. Monte Carlo simulation is a very large subject that is studied extensively in Operations Research. It is much broader than just generating random numbers of a known distribution. It includes simulating any situation where randomness has a significant effect (traffic simulation, combat, queueing theory, spares management, etc.) Some (admittedly old) books to give you an idea of the breadth of the subject are "Monte Carlo Methods" by Hammersley and Handscomb and "Computer Simulation Techniques" by Naylor, Balintfy, Burdick, and Chu. The first emphasizes the math and the second emphasized the computer implementation (given the limited simulation languages at that time). Maybe someone can suggest more recent references.

Can you write computer programs? "Monte-Carlo simulation" is very general subject. Suppose your wrote a computer program which had steps in it where the computer drew pseudo-random numbers to determine the outcome. The program might simulate physics, economics or just a game. Such a program is a "Monte-Carlo simulation" and if you ran it many times to get the statistics of its output, you could say you were using "Monte-Carlo simulation".

Monte-Carlo simulations on computers do use functions that generate pseudo-random numbers. The numbers are not always from normal distributions. The usual procedure is to generate pseudo-random numbers from a uniform distribution and then, if another type of distribution is desired, apply an algorithm to these uniformly distributed numbers to produce other distributions.

hi Stephen,
Thanks for the explanation, it helps me a lot.
I did lots of simulation using different distributions such as Normal distribution & Rayleigh distribution in Matlab to obtain Bit error rate in wireless telecommunication without realizing that actually I've monte carlo simulation.
Only few papers mention monte carlo simulation, the rest just mention add this AWGN or Rayleigh distribution, that's why i am not clear myself.
