On the Power and Limitations of Branch and Cut COMPUTATIONAL COMPLEXITY In 2014, I wrote a blog post about a fake company Elfdrive.. With a near record-setting investment announced last week, the self-driving car service Elfdrive is the hottest, most valuable technology start-up

on the planet.

COMPUTATIONAL COMPLEXITY: 2021 I first wrote about bitcoin in this blog ten years ago after I gave a lecture in a cryptography class I taught at Northwestern. Two years later I had a follow-up post, noting the price moved from $3 to $1000 with a market cap of about $11 Billion.My brother who thought they were a scam back then has since become a cryptocurrency convert. COMPUTATIONAL COMPLEXITY: 2020 Of course when we think back at 2020 it won't be the theorems but the pandemic, a divisive election and racial reckoning. The word of the year for academia is "virtual", virtual teaching, virtual research collaborations, virtual talks, virtual conferences, virtual panels and

virtual job visits.

COMPUTATIONAL COMPLEXITY: 2019 Some great theorems this year including non-deterministic double exponential time by quantumly entangled provers and integer multiplication in O(n log n) time.But the result of the year has to go to a paper that gave a shockingly simple proof of a major longstanding

conjecture.

COMPUTATIONAL COMPLEXITY: THE FUTURE OF FACULTY HIRING Faculty hiring in computer science is a process long due for an overhaul.The pandemic certainly changed some of the dynamics moving most of the interviews online and saving a COMPUTATIONAL COMPLEXITY CONFERENCE CCC'20 Program. Schedule: The talks for the award winning papers are 30 minutes long and the talks for the other accepted papers are 10 minutes long. The time slots include the time for questions. All times below are in Eastern Daylight Time (EDT). There are invited talks on COMPUTATIONAL COMPLEXITY CONFERENCE Submission. Deadlines: Papers must be submitted electronically via the submission server, and received by Monday, February 15, 2021, 5:00 pm PST.Notification of acceptance will be sent by April 30, 2021, and final camera-ready copies of accepted papers will be due in mid May 2021.. Format: Submissions should start with a title page consisting of the title of the paper; each author's name COMPUTATIONAL COMPLEXITY: 2020 Of course when we think back at 2020 it won't be the theorems but the pandemic, a divisive election and racial reckoning.

OPTIMAL QUANTUM SAMPLE COMPLEXITY OF LEARNING ALGORITHMS 1/ 23 Optimal Quantum Sample Complexity of Learning Algorithms Srinivasan Arunachalam (Joint work with Ronald de Wolf) CONFERENCE ON COMPUTATIONAL COMPLEXITY Letter of Support. On May 16, 2014, after many deliberations within the committee and with the entire community of scholars engaged with the Conference on Computational Complexity (CCC), the steering committee of CCC decided to pursue a separation from IEEE and the formation of an independent organization to run the conference. COMPUTATIONAL COMPLEXITY: 2018 In last year's review we talked about the magical breakthroughs of machine learning. This year we seemed to have moved beyond the magic to where machine learning has become a thing. We see the immense value of data and continue to struggle with the ethical challenges of collecting and acting on data, dominance of the big tech companies, training all these students who want to gain expertise in COMPUTATIONAL COMPLEXITY: 2002 In 2004 for the first time the FOCS conference will be held outside the United State or Canada. The 45th FOCS conference will be held in Italy. STOC held its first conference outside of North America in 2001 in Greece.. First some background on these conferences quoted from the preface of David Johnson's 1991 STOC/FOCS Bibliography.
