Optimal Denominations for Coins and Bank Notes: In Defense of the Principle of Least Effort
反驳了用标准砝码问题类比货币面额优化的观点，指出两者关键不同，并主张面额优化是多目标问题，应最重视最小努力原则。
A number of recent articles argue that the "problem of Bachet"--the problem of finding the most efficient set of standard weights--can shed light on the problem of finding the optimal denominations of coins and bank notes. The present note opposes this view and shows that the two problems are different in a key way. It also argues that finding the optimal denominational structure is a multicriteria optimization problem, in which the principle of least effort should be given the greatest weight.
