Poring over the possibilities of ordering chicken nuggets might seem like a trivial affair, but the concept of the Frobenius Number appears in important aspects of real life. It’s the beginning of thinking about optimization in certain areas, like the coin-based currencies we use worldwide. What denominations of coins are best mathematically? Which combinations fit best with how humans actually think and live?
And that’s how we started thinking about whether the United States could need an 18-cent coin.
By looking how we can combine nuggets and how we utilize coins — including a “greedy algorithm” that helps us select the method in which we make change — I found that sometimes the most optimal mathematical way of doing things just isn’t the right fit for how we navigate the world.
