12- 4. What Is the Most Efficient Base?
Suppose you are building a computer and you are trying to decide what base to use to represent integers. For the registers you have available circuits that are 2-state (binary), 3-state, 4-state, and so on. Which should you use?
Let us assume that the cost of a b-state circuit is proportional to b. Thus, a 3-state circuit costs 50% more than a binary circuit, a 4-state circuit costs twice as much as a binary circuit, and so on.
Suppose you want the registers to be able to hold integers from 0 to some maximum M. Encoding integers from 0 to M in base b requires
digits (e.g., to represent all integers from ...
