Seminar “Coping with NP-hard problems by using parameterized algorithms”
Seminar with Professor Jan Arne Telle
16 september 2021, 4PM
Room 336 INESC-ID
“Coping with NP-hard problems by using parameterized algorithms”
The talk will give an introduction to the field of parameterized complexity, which focuses on classifying computational problems according to their inherent difficulty with respect to /multiple/ parameters of the input. The complexity of a problem is then measured as a function of those parameters.
This allows the classification of NP-hard problems on a finer scale than in the classical setting, where the complexity of a problem is only measured as a function of the number of bits in the input.
We will give some concrete applications:
1 A kernelization algorithm for k-Vertex Cover (k-VC, use natural parameter).
2 A Fixed Parameter Tractable (FPT) algorithm for k-VC.
3 Dominating Set (DS) is not FPT for the natural parameter.
4 Introduce Treewidth tw.
5 DS is FPT parameterized by tw.
6 A hierarchy of graph parameters.
7 An application to satisfiability
Workshop Metabolism and mathematical models: Two for a tango
Dates: November 18-19, 2021
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.
