Computer Simulations
Important concepts
What is a computer simulation?
What is involved in the process of creating a simulation?
Example simulations
A portion of these notes were based on the book "Computer Simulation" by Watson and Blackstone

What Is Simulation?
Recreating behaviour by an analogous model or situation to gain information more conveniently or to train personnel.

What Is A Computer Simulation?
A computer model of the real world
Consists of three steps1. Design2. Execution3. Analysis
