open-in-new

It is used by many algorithms related to <a href="/facts/Pricing/e2r3HKdI">pricing</a> and optimization in <a href="/facts/Online_marketplace/QsvgxEly">online market</a>. It is usually contrasted with a value oracle, which is a function that, given a set of items, returns the value assigned to them by an agent. </p>
