Beyond Smoothed Analysis: Analyzing the Simplex Method by the Book Narrowing the gap between theory and practice is a longstanding goal of the algorithm analysis community. To further progress our understanding of how algorithms work in practice, we propose a new alg...

The simplex algorithm is super efficient. 80 years of experience says it runs in linear time. Nobody can explain _why_ it is so fast.

We invented a new algorithm analysis framework to find out.

The word ‘head’ is etymologically related to ‘chef’, the head of a kitchen. And to ‘chief’, the head of a group.

These are also related to ‘cape’, a headland, and ‘per capita’, literally “by heads” – and yes, to Spanish ‘cabeza’ too.

Zoom in on my new graphic to learn all about this word family:

I’m looking for postdocs and PhD students to join my group at Cambridge!

Topics include: Classical & Quantum Complexity, Sublinear Algorithms, Coding Theory, Cryptography, Learning Theory, and their interplay with Fourier Analysis & Additive Combinatorics.

To apply or inquire, email me your CV.

In a series of posts, we aim to present a set of essential tools & techniques that we believe every aspiring quantum information theorist should have in their toolbox. 🧰🛠️

We think these techniques will also be useful for researchers in adjacent fields.

All tools will be linked in this thread: 🧵

Dear colleagues, positions at CNRS (and INRIA) will (in all probability) be announced this winter. By then it will however be too late to properly prepare an application. Recent PhDs, postdocs etc interested in such positions should get right now in contact with teams who would like to recruit them.

Surtout quand c'est une *déclaration*

With September (already!) underway, the next season of TCS+ will start soon. As we are planning for it, a reminder that you can—and are encouraged to!—submit suggestions for talks and speakers on our website: sites.google.com/view/tcsplus...

Je découvre une agence qui vent des conférences de chercheurs ou d’ingénieurs. Ok. S’il y a un marché. Mais je rappelle aux enseignant·es (si besoin) que de nombreuses et nombreux chercheur·ses, enseignant·es chercheurs·ses viendront gratuitement. Invitez-les.

Quand les boomers climatosceptiques prétendent que les températures actuelles ne sont pas exceptionnelles, montrez-leur cette vidéo.

Sophie Huiberts (@sophie.huiberts.me), from the CNRS, will give an online talk at @optima-arc.bsky.social next week, Wed 20, 4-5pm AEST 🇦🇺, on the "Smoothed analysis of the simplex method" (settling it!)

To attend, see the OPTIMA website: optima.org.au/events/semin...

You have to organize it in a venue near the water. Jussieu is just by the Seine so the crabs can easily come.

Is this TCS track A or track B?

thanks!

Yes, that was what I thought. And do I understand correctly that the criticism on the mentioned paper is that in their case, their natural implementation is no easier than the qubit ones?

Dumb question by a non-physicist: is it theoretically possible/plausible that Shor's algorithm can be run in a single quantum oscillator? My naive view is that its infinite Hilbert space has all dimensions that are needed. I understand that doing it in practice would be beyond any QC optimism.

It's time for the Theory Jobs spreadsheet for 2025! The theory CS community crowdsources who accepted which jobs every year.
