''In time, those Unconscionable Maps no longer satisfied...''

''If we are to discuss the limitations of simulation, we must define what simulation is. The literature in the field is of limited usefulness in tying down exactly what the term describes. The more recent the document, the more likely it is that the author will quote several alternate definitions, reject them all and proceed to develop his own definition which is more general and less restricting than any of those given. The use of the term "simulation" seems to outgrow even the broadest definition. I will not attempt a precise definition, but as an alternate will suggest that the history of the development of simulation as we know it today may be a less rigorous, but more satisfying way to describe simulation. The origins of simulation are generally traced to the work of Von Neuman and Ulman in the late 1940's. They coined the term "Monte Carlo Analysis" to describe a technique whereby essentially deterministic problems, too expensive or complex to solve analytically, could be solved by treating them as stochastic problems.''
