Multidimensional Scaling: Approximation and Complexity

no code implementations23 Sep 2021 Erik Demaine, Adam Hesterberg, Frederic Koehler, Jayson Lynch, John Urschel

In particular, the Kamada-Kawai force-directed graph drawing method is equivalent to MDS and is one of the most popular ways in practice to embed graphs into low dimensions.

Solving Machine Learning Problems

1 code implementation2 Jul 2021 Sunny Tran, Pranav Krishna, Ishan Pakuwal, Prabhakar Kafle, Nikhil Singh, Jayson Lynch, Iddo Drori

Our system demonstrates an overall accuracy of 96% for open-response questions and 97% for multiple-choice questions, compared with MIT students' average of 93%, achieving grade A performance in the course, all in real-time.

Hardness of Token Swapping on Trees

no code implementations11 Mar 2021 Oswin Aichholzer, Erik D. Demaine, Matias Korman, Jayson Lynch, Anna Lubiw, Zuzana Mas, Mikhail Rudoy, Virginia Vassilevska Williams, Nicole Wein

We also show limitations on approximation of sequential token swapping on trees: we identify a broad class of algorithms that encompass all three known polynomial-time algorithms that achieve the best known approximation factor (which is $2$) and show that no such algorithm can achieve an approximation factor less than $2$.

Recursed is not Recursive: A Jarring Result

2 code implementations12 Feb 2020 Erik Demaine, Justin Kopinsky, Jayson Lynch

Recursed is a 2D puzzle platform video game featuring treasure chests that, when jumped into, instantiate a room that can later be exited (similar to function calls), optionally generating a jar that returns back to that room (similar to continuations).

Who witnesses The Witness? Finding witnesses in The Witness is hard and sometimes impossible

1 code implementation26 Apr 2018 Zachary Abel, Jeffrey Bosboom, Michael Coulombe, Erik D. Demaine, Linus Hamilton, Adam Hesterberg, Justin Kopinsky, Jayson Lynch, Mikhail Rudoy, Clemens Thielen

We analyze the computational complexity of the many types of pencil-and-paper-style puzzles featured in the 2016 puzzle video game The Witness.
