#### Almost Famous Quantum Polynomial Time

I have been playing with a new complexity class AFQP, defined in a yet-to-be-published manuscript by Alagna and Fleming. A language L is in AFQP if there is a polynomial...

#### A Reduced Turing Award

A Turing machine has an extremely simple instruction set: Move left, move right, read and write. If you want to do real programming, you need something a bit...

#### Data-Driven Programming

Five years ago I posted about Flash Fill, a then new Microsoft Excel feature that would reformat data based on examples. I just checked the latest version of Excel...

From Computational Complexity
#### Me and My Bolt

On Tuesday I got a knock on my car's window. Rolling it down someone asked if I liked my car as he was thinking of buying one himself. Was I driving the...

#### NP is Hard

You don't get much press by stating conventional beliefs--there is no "round earth society". Nevertheless there are serious researchers out there trying to sayI...

#### Corporate Education

First of all read the #metoo testimonial going around the TCS blogosphere. Our field is not immune.
Last Sunday Frank Bruni wrote an op-ed column Corporations,...

#### For the Love of Algorithms

Wired magazine labelled 2017 as The Year We Fell Out of Love with Algorithms. The article goes on to talk about how algorithms give us filter bubbles, affect elections...

From Computational Complexity
#### Flying Blind

Many computer science conferences have made a number of innovations such as a rebuttal phase, multi-tiered program committees, a hybrid journal/conference model...

#### From Art to Science

Q: Why did the neural net cross the road?
A: Who cares along as it got to the other side.
Whit Diffie and Martin Hellman in their classic 1976 paper talk about...

From Computational Complexity
#### A Sensitive Game

Last month I posted about the sensitivity conjecture and today I would like to talk about an interesting game developed by Gilmer, Koucký and Saks and independently...

#### Complexity Year in Review 2017

Theorem of the year goes to the resolution of the dichotomy conjecture. I wrote about the conjecture in February and while the Feder et. al paper didn't hold up...

From Computational Complexity
#### Having Faith in Complexity

I believe P ≠ NP as much as anyone else. Nevertheless should we worry about trust we put in complexity?
You don't need the full power of P = NP to break cryptography...

#### Our AI future: The good and the Ugly

I don’t directly work in machine learning but one cannot deny the progress it has made and the effect it has on society. Who would have thought even a few years...

From Computational Complexity
#### Razor's Edge

Informally the sensitivity conjecture asks whether every hard Boolean function has a razor's edge input, where flipping a random bit has a reasonable chance ofrecent...

#### Kolmogorov Complexity and the Primes

Bill's post on how to derive the non-finiteness of the primes from Van der Waerden's theorem reminds me of a nice proof using Kolmogorov complexity.
A quick primer...
