The "optimal denomination problem" is a problem for people who design entirely new currencies: What denominations should be chosen for the coins in order to minimize the average effort required to make change -- i.e., the average number of coins needed to make change?
Problem optimalnog apoena je problem za ljude koji modeluju sasvim nove vrednosti: koje apoene treba izabrati u cilju smanjenja prosečne složenosti pravljenja kusura (npr. koji je prosečan broj novčića potreban da bi se napravio kusur?).
