Evolutionary Mechanism Design
|
The advent of large-scale distributed systems poses unique engineering challenges. In open
systems such as the internet it is not possible to prescribe the behaviour of all of the
components of the system in advance. Rather, we attempt to design infrastructure, such as
network protocols, in such a way that the overall system is robust despite the fact that
numerous arbitrary, non-certified, third-party components can connect to our system.
Economists have long understood this issue, since it is analogous to the design of the rules
governing auctions and other marketplaces, in which we attempt to achieve sociallydesirable
outcomes despite the impossibility of prescribing the exact behaviour of the
market participants, who may attempt to subvert the market for their own personal gain.
This field is known as 'mechanism design': the science of designing rules of a game to
achieve a specific outcome, even though each participant may be self-interested. Although
it originated in economics, mechanism design has become an important foundation of
multi-agent systems (MAS) research. In many scenarios mechanism design and auction
theory yield clear-cut results; however, there are many situations in which the underlying
assumptions of the theory are violated due to the messiness of the real-world. In this thesis
I introduce an evolutionary methodology for mechanism design, which is able to incorporate
arbitrary design objectives and domain assumptions, and I validate the methodology using
empirical techniques.
