Fair division methods
method for dividing a cake — and will play an important conceptual role later on. Under this protocol, player 1 cuts the cake into two pieces that he values equally, and player 2 subsequently chooses the piece that he prefers, giving the other piece to player 1. The resulting allocation is fair in a precise, formal sense known as envy-freeness:
The fair division approach is a 51 contemporaneous and active area within the management science field, in which algorithms are 52 developed to divide up limited resources among competing interests and satisfy a suitable equity 53 criterion. The fair division method was first introduced by Steve Brams and Alan Taylor in their
The method of markers applies to problems of fair division in which the goods could be arranged in a linear fashion. This may be the case of a large number of small items to be shared, or a continuous item, like a gold chain, to be cut into pieces. That done, each of the N players indicates his or her opinion as regard a fair division by ...Fair division methods are hard to compare as each one was designed with a different goal in mind. One way to deal with the problem is axiomatic analysis. Finding out which method satisfies which fair-ness properties and make a choice based on this analysis. Policy makers, however, might needOnce you are familiar with the various methods of fair division, see if you can invent a division procedure of your own. But be sure to verify that it satisfies the conditions of being a true fair division strategy. Another variation of fair division problems is requiring that the results to be “envy-free”: In an envy-free division, every ...8: Fair DivisionThe second part of the course will introduce the general theory of fair division (including cake-cutting algorithms and an introduction to the theory of social welfare).

Cutting the cake algorithm is the following. 1. Let (1) divide cake into three equal pieces. 2. Ask others the following: "Please, list all the pieces, you will be satisfied with." 3. Consider bipartite graph with 2n-1 vertices: n pieces of cake and all children except (1).
A fair share, in the case we are talking here is any share that in the opinion of the person getting it is at least "one Nth" of the item (s) to be divided. Here N is the number of players. Let's note here that this "fair share" is relative to the one receiving it. The opinion of the others doesn't matter. In otherwords, we are implying only ...Three partners are dividing a plot of land among themselves using the Lone Divider method. P1 is chosen to divide the property into three parcels s1, s2, and s3. P2 bid list is {s2} and P3 bid list is {s1, s3}. What is one fair division of the parcels? Exp #2: Four Friends are trying to split a pizza using Lone-Divider Method. Identify the divider.Fair division methods are hard to compare as each one was designed with a different goal in mind. One way to deal with the problem is axiomatic analysis. Finding out which method satisfies which fair-ness properties and make a choice based on this analysis. Policy makers, however, might needFour Voting Methods. The applet below helps practice and gain insight into four voting methods: Plurality, Borda, Plurality with Elimination, Pairwise Comparison.

Solution Algorithm: 1. each party distributes 100 points over the items in a way that reflects their relative worth to that party.
Arguably, the two most popular fairness notions are of envy-freeness (EF) [17,31] and proportionality (Prop) [30]. EF requires that every agent (weakly) prefers her own allocation than anyone else ...2.4 Lone Divider Method • Continuous method. 1. Divider divides cake into three equal objects. 2. Each chooser declares (secretly) which pieces are fair shares. 3. Divide by bids: (a) If possible, give each player a piece they bid for.

The first person wants to cut the cake so as to maximize his share min ( x, 1 – x ). The maximum value of min ( x, 1 – x) for x between 0 and 1 occurs when x = 0.5, which means 1 – x is also 0.5. So the first player will cut the cake into 2 equal slices and the “I cut, you choose” method produces a fair division of the cake.

In this method, the parties are randomly assigned an order, perhaps by pulling names out of a hat. The method then proceeds as follows: 1) The first person cuts a slice they value as a fair share. a. If they think it is worth less than a fair share, they then pass on the piece unchanged. b.Step 2. Arbitrarily select one of the players as Player 1. Compute a value ratio for each item as the quotient of player 1's score divided by player 2's score.
