Scientists working in the area of distributed function optimization have to deal with a huge variety of optimization techniques and algorithms. Most of the existing research in this domain make use of tightly-coupled systems that either have strict synchronization requirements or completely rely on a central server, which coordinates the work of clients and acts as a state repository. The possibility of performing such optimization tasks in a P2P decentralized network of solvers has been investigated and explored, obtaining quite promising results.
Marco Biazzini, a former Ph.D. student of mine, designed and developed P2Poem, a ‘P2P Optimization Epidemic Middleware’ that aims to bridge the gap between the issues related to the design and deployment of large-scale P2P systems and the need to easily deploy and execute optimization tasks in such a distributed environment. His work has been published in several conferences [IPDPS08] [GECCO09] [AEC09] [ICPADS10] and summarized in a journal paper [PPNA13].
