When you lose your phone, wallet, or keys, you may resort to a few tricks to relocate them. Maybe you’ll retrace your steps. Maybe you’ll look in each of the locations that you typically put them. Or perhaps you’ll try to remember every unusual place you’ve been lately. Each of these choices makes logical sense.

When an entity with vast resources loses something extraordinarily valuable, like a nuclear submarine, they call in the big guns of Bayesian search theory to help. Fortunately for the rest of us, the basic concepts are simple enough to distill for finding those everyday items. Even if your missing item is worth merely hundreds of dollars, this mathematical process can streamline the logic of your search, saving you time and money.
