Questions tagged [simulation]

A vast area which includes generating results from computer models.

Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time

(source: Wikipedia)

For understanding when to use simulation, refer to the following question:

How to simulate the random variable $Y$ using another random variable $X$?

Let $X$ be the discrete uniform random variable on taking values in the set $\{1,2,3,4,5\}.$ We want to simulate the random variable $Y$ which is the discrete uniform random variable taking values in the set $\{1,2,3,4,5,6,7\}.$ Let generate_X() be…

passive heatsink simulation

I want to simulate a heat source (eg a cpu) connected to a heatsink without any cooling fans. The simulation will run indefinitely using small time steps. What i want to measure at each time step is the temperature of the heat source and the…

Simulate a random variable

I wish to simulate the random variable according to pdf $$ f(x)=xe^{-x} $$ I have to feeling that I should first simulate an exponential random variable $t$ with parameter -1 and try to use the composition method, but can't seem to figure out…
