The Adjusted Winner procedure is a method for dividing a set of indivisible goods between two parties. It aims to achieve an equitable division by considering the preferences of each party for each item. The procedure begins by assigning each item to the party that values it more. Then, it iteratively transfers portions of items from the party that has a higher total value to the other party, until the total value received by each party is as close as possible. The "adjustment" comes from splitting items, which is conceptually done by assigning a fraction of the item's value to each party. This process ensures that no item is completely allocated to a party that values it less than the other, and it minimizes the difference in total value received by each person. The Adjusted Winner procedure is particularly useful in situations where items cannot be physically divided, such as dividing heirlooms or allocating resources. It is a mechanism designed to reduce envy by making each party as satisfied as possible given the constraints of indivisible goods and the other party's claims. The core principle is to ensure that the final allocation reflects the relative valuations of the two parties as closely as possible, striving for a Pareto efficient outcome where no further adjustments can be made to make one party better off without making the other worse off.
