Learning and Recommending Shortcuts in Semantic Peer-to-Peer Networks
University of Karlsruhe –
A major problem within peer-to-peer systems is to find the best
peer given a certain query. Inspired by the work in the area of
social networks we present a novel peer-to-peer system called
INGA (Interest-based Node Grouping Architecture). Peers
cooperate to efficiently route queries along adaptive shortcuts
based overlays using only local knowledge. We propose active and
passive shortcut creation strategies and a new routing algorithm
that combines a greedy, high degree and flooding based search
depending on one’s knowledge. We quantify the benefit of the
overlay network by comparing the performance of INGA in the SWAP
simulation infrastructure against a simple Gnutella style network,
against recently proposed shortcut networks without similarity
metrics and against a relaxation based approach. While obtaining
the same recall we show in our experiments that with INGA we half
the messages for a query.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
