Major breakthrough in graph streaming arxiv.org/abs/2607.14656 - the naive greedy matching algorithm is optimal! This resolves a huge open problem in this area (and other problems too). Big congrats to the authors: Sepehr Assadi, Max Jiang, Mars Xiang!
I'm excited to announce that I just started as a postdoctoral fellow @Georgetown hosted by @SuccinctJT! I look forward to working closely with Justin and others at Georgetown and also with my collaborators @DIMACSCenter, where I shall be a visitor for the next few months.
The videos are also linked to the respective talk titles in the program here: sites.google.com/view/dimacs…
Have fun (re)watching them!
Most video recordings of our workshop (Modern Techniques on Graph Algorithms: sites.google.com/view/dimacs…) are online now at youtube.com/playlist?list=PL…. Thanks to all speakers and participants for making it a success!
All speakers and talks have been finalized. The schedule for the workshop is now out. Register soon if you haven't already!
Reminder: tomorrow is the last day for submitting posters. Hurry!

When you get to learn more about a topic while teaching it, that's the best! 🙂
Parting gift from @prantarg who taught discrete math at #dartmouth before heading off to #DIMACS postdoc: a lovely proof (by a student, under exam conditions!) that I hadn't seen before.
Just paused working on Overleaf to send an email. Completed only the first sentence and hit Ctrl+Enter. Email Sent🥲🥲
Delighted to announce that I successfully defended my PhD thesis yesterday. Grateful to my advisor @amitc1 for his excellent guidance over the last 5 years. Thanks to my committee members, friends, and family who supported me and made this achievement possible.
I'm also excited to announce that I'll stay as a lecturer @dartmouth over the summer and teach Discrete Math. In the Fall, I'll join @DIMACSCenter as a Simons Postdoctoral Leader. I look forward to working closely with everyone there!
Pleased to know that our work "A New Dynamic Algorithm for Densest Subhypergraphs" was nominated for Best Paper Award @TheWebConf!
It was among the top 11 out of 323 papers accepted from 1822 submissions!!
Congrats to my coauthors @SumanKBera, Sayan Bhattacharya, and @jayeshc17!
Adjectives for a number that's on the lower side but not too low either? It's more than what "a few" implies but less than what "a significant number of" does. I feel it's best expressed by "non-trivially many," but not sure if it's acceptable in articles like, say, my thesis..🤔

Surely, Wimbledon banned itself when Britain invaded Iraq, Afghanistan, and Libya. 🤔
NEWS: Russian tennis players will be barred from competing at Wimbledon in June, a decision that will prevent current world No. 2 @DaniilMedwed from playing in the season’s third Grand Slam.

There's been a recent surge of interest in "adversarially robust" streaming. Here, an adaptive adversary continues the stream based on past outputs received. In a paper (arxiv.org/pdf/2109.11130.pdf, ITCS'22) with @amitc1 and Manuel Stoeckl, we study graph coloring in this model.

3. We give a Δ³-coloring robust algo in ~O(n) space. Coupled with results of a parallel work (Assadi, Chen, Sun, ArXiv '21), this shows the first double separation for a streaming problem (colors needed for ~O(n) space)
Standard: Δ+1
Robust: poly(Δ)
Deterministic: exp(Δ^O(1))

For questions and discussions, catch the live talk by Manuel at ITCS Session 12 on Feb 1!
