Prior-free mechanism design
Let's imagine you and your friend have a candy jar that you want to share equally. You both have different preferences for candy, so you want to design a way to divide the candy that is fair for both of you. This is called "mechanism design."
Now, imagine you don't know anything about what kinds of candy your friend likes, or how much they like each type. This is where "prior-free" mechanism design comes in. It means we don't have any information about what people's preferences are before we design the mechanism.
So, to make it fair, you and your friend could take turns picking candies from the jar until it's empty. That way, you both get an equal opportunity to choose your favorite candies, and neither of you has an advantage because you don't know what either person likes. This is an example of a prior-free mechanism design for candy sharing.
In more complex situations, like auctioning off items or allocating resources, prior-free mechanism design can be more difficult. But the idea is the same – we want to design a fair system for everyone involved, even if we don't have any information about their preferences beforehand.
