Negotiating Socially Optimal Allocations of Resources
A multiagent system may be thought of as an artificial society of autonomous
software agents and we can apply concepts borrowed from welfare economics and
social choice theory to assess the social welfare of such an agent society. In
this paper, we study an abstract negotiation framework where agents can agree
on multilateral deals to exchange bundles of indivisible resources. We then
analyse how these deals affect social welfare for different instances of the
basic framework and different interpretations of the concept of social welfare
itself. In particular, we show how certain classes of deals are both sufficient
and necessary to guarantee that a socially optimal allocation of resources will
be reached eventually
Modelling Multilateral Negotiation in Linear Logic
We show how to embed a framework for multilateral negotiation,
in which a group of agents implement a sequence of deals
concerning the exchange of a number of resources, into linear logic.
In this model, multisets of goods, allocations of resources, preferences
of agents, and deals are all modelled as formulas of linear logic.
Whether or not a proposed deal is rational, given the preferences of
the agents concerned, reduces to a question of provability, as does
the question of whether there exists a sequence of deals leading to an
allocation with certain desirable properties, such as maximising social
welfare. Thus, linear logic provides a formal basis for modelling
convergence properties in distributed resource allocation
Allocation in Practice
How do we allocate scarcere sources? How do we fairly allocate costs? These
are two pressing challenges facing society today. I discuss two recent projects
at NICTA concerning resource and cost allocation. In the first, we have been
working with FoodBank Local, a social startup working in collaboration with
food bank charities around the world to optimise the logistics of collecting
and distributing donated food. Before we can distribute this food, we must
decide how to allocate it to different charities and food kitchens. This gives
rise to a fair division problem with several new dimensions, rarely considered
in the literature. In the second, we have been looking at cost allocation
within the distribution network of a large multinational company. This also has
several new dimensions rarely considered in the literature.Comment: To appear in Proc. of 37th edition of the German Conference on

Allocating Limited Resources to Protect a Massive Number of Targets using a Game Theoretic Model
Resource allocation is the process of optimizing the rare resources. In the
area of security, how to allocate limited resources to protect a massive number
of targets is especially challenging. This paper addresses this resource
allocation issue by constructing a game theoretic model. A defender and an
attacker are players and the interaction is formulated as a trade-off between
protecting targets and consuming resources. The action cost which is a
necessary role of consuming resource, is considered in the proposed model.
Additionally, a bounded rational behavior model (Quantal Response, QR), which
simulates a human attacker of the adversarial nature, is introduced to improve
the proposed model. To validate the proposed model, we compare the different
utility functions and resource allocation strategies. The comparison results
suggest that the proposed resource allocation strategy performs better than
others in the perspective of utility and resource effectiveness.Comment: 14 pages, 12 figures, 41 reference
Fully Proportional Representation as Resource Allocation: Approximability Results
We model Monroe's and Chamberlin and Courant's multiwinner voting systems as
a certain resource allocation problem. We show that for many restricted
variants of this problem, under standard complexity-theoretic assumptions,
there are no constant-factor approximation algorithms. Yet, we also show cases
where good approximation algorithms exist (briefly put, these variants
correspond to optimizing total voter satisfaction under Borda scores, within
Monroe's and Chamberlin and Courant's voting systems).Comment: 26 pages, 1 figur
Multiagent negotiation for fair and unbiased resource allocation
This paper proposes a novel solution for the n agent cake cutting (resource allocation) problem. We propose a negotiation protocol for dividing a resource among n agents and then provide an algorithm for allotting portions of the resource. We prove that this protocol can enable distribution of the resource among n agents in a fair manner. The protocol enables agents to choose portions based on their internal utility function, which they do not have to reveal. In addition to being fair, the protocol has desirable features such as being unbiased and verifiable while allocating resources. In the case where the resource is two-dimensional (a circular cake) and uniform, it is shown that each agent can get close to l/n of the whole resource.Utility theory ; Utility function ; Bargaining ; Artificial intelligence ; Resource allocation ; Multiagent system
