Due Date: September 25, 2007
Hand In: Printout of program code and dialogue of how it runs.
Purpose: This homework is intended to gain experience with testing of Random Number Generators.
Description:
Start with the TestRandomNumberGenerator program that we did in class.
1. Write a Random number generator that uses the “Middle Square” method of generating a random sequence
and add it to the program.
2. Test the LCG number generator with the following values for “a” and “m”.
a. a=23, m=10^8+1. Used by Lehmer in 1948
b. a=69069, m=2^32
c. make up your own values of a and m.
Extra Credit:
Write a random number generator that generates a Gaussian rather than uniform distribution and test it with the
TestRandomNumberGenerator program.
