A stochastic simulation is a simulation of a system that has variables that can change stochastically (randomly) with individual probabilities. Realizations of these random variables are generated and inserted into a model of the system. Outputs of the model are recorded, and then the process is repeated with a … Visa mer Stochastic originally meant "pertaining to conjecture"; from Greek stokhastikos "able to guess, conjecturing": from stokhazesthai "guess"; from stokhos "a guess, aim, target, mark". The sense of "randomly … Visa mer It is often possible to model one and the same system by use of completely different world views. Discrete event simulation of a problem as well as continuous event … Visa mer For simulation experiments (including Monte Carlo) it is necessary to generate random numbers (as values of variables). The problem is that the computer is highly deterministic machine—basically, … Visa mer In order to determine the next event in a stochastic simulation, the rates of all possible changes to the state of the model are computed, and then ordered in an array. Next, the … Visa mer While in discrete state space it is clearly distinguished between particular states (values) in continuous space it is not possible due to … Visa mer Monte Carlo is an estimation procedure.
