A popular way of generating random numbers is using this recursive formula: x = (a * x' + c)%m where x' is the previous x (or the seed if there is no previous x). Tweaking the constants effect how "random" the numbers are. Graphing x against x' reveals patterns that show how effective a particular set of constants are at generating random numbers. (full post)
