 ModelBenders - Encyclopedia
Simulation is the process of designing a model of a real or imagined system and conducting experiments with that model.
Simulations are usually referred to as either discrete event or continuous, based on the manner in which the state variables change.
In practice, most simulations use both discrete and continuous state variables, but one of these is predominant and drives the classification of the entire simulation.

Simulations of complex social processes involve the estimation of many parameters and adequate data for making the estimates can be difficult to come by.
The simulation works by cycling through each agent in turn, collecting messages sent from other agents, updating the agent's internal state by checking for any applicable rules, deciding on an action for the agent to take and finally communicating messages and the effects of the action to the environment, which then responds appropriately.
The simulation was used to investigate issues such as whether the formation of groups increases the chances of survival of the agents.

 WHAT IS SIMULATION?
Computer simulation is the discipline of designing a model of an actual or theoretical physical system, executing the model on a digital computer, and analyzing the execution output.
Computer simulation is the electronic equivalent of this type of role playing and it serves to drive synthetic environments and virtual worlds.
Simulation of a system can be done at many different levels of fidelity so that whereas one reader will think of physics-based models and output, another may think of more abstract models which yield higher-level, less detailed output as in a queuing network.

 Computer Assisted Simulation Design
Unlike physical simulations, conflict simulations usually cannot be validated by conducting experiments in a laboratory environment.
As in weather prediction, where multiple models are applied in search of a convergence, accurate conflict simulation requires the application of multiple models, or at least the same model with different values applied to parameterized elements.
Whatever the goal of a conflict simulation may be, designing an effective simulation model requires an understanding of the interplay between simulation components.

 Our Lives, Controlled From Some Guy’s Couch - New York Times
This simulation would be similar to the one in “The Matrix,” in which most humans don’t realize that their lives and their world are just illusions created in their brains while their bodies are suspended in vats of liquid.
Dr. Bostrom assumes that technological advances could produce a computer with more processing power than all the brains in the world, and that advanced humans, or “posthumans,” could run “ancestor simulations” of their evolutionary history by creating virtual worlds inhabited by virtual people with fully developed virtual nervous systems.
Some computer experts have projected, based on trends in processing power, that we will have such a computer by the middle of this century, but it doesn’t matter for Dr. Bostrom’s argument whether it takes 50 years or 5 million years.
