[sdiy] Analog Computers ( again )

[Grant Richter]

He did a companion book called "Random-Process Simulation and  
Measurements". Granino A. Korn

For equations above a certain number of variables, a solution can  
actually be found faster by connecting random number generators for  
the variables and let the simulation run until the bell goes "ding".  
This is called a "Monte-Carlo" solution.

This book has information on Sources of Uncertainty and other random  
function generators.
