On the Geometry of Stabilizer States. (arXiv:1711.07848v1 [quant-ph])

Wednesday, November 22, 01:30 UTC @ cs.CG updates on arXiv.org

Large-scale quantum computation is likely to require massive quantum error correction (QEC). QEC codes and circuits are described via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them. Such states are obtained by stabilizer circuits (consisting of CNOT, Hadamard and Phase gates) and can be represented compactly on conventional computers using $O(n^2)$ bits, where $n$ is the number of qubits. As an additional application, the work by Aaronson

XSAT of Exact Linear CNF Classes. (arXiv:1711.07474v1 [cs.CC])

Wednesday, November 22, 01:30 UTC @ cs.CC updates on arXiv.org

It is shown that l-regularity implies k-uniformity in exact linear CNF formulas. Consequences for exact satisfiability of this formula class are discussed. In particular it is proven that XSAT-satisfiabilty can be decided in sub-exponential time, namely O(exp(sqrt(n))), for l-regular exact linear monotone CNF formulas.

Aligned Drawings of Planar Graphs. (arXiv:1708.08778v3 [cs.DS] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

Let $G$ be a graph topological embedded in the plane and let $\mathcal A$ be an arrangement of pseudolines intersecting the drawing of $G$. An aligned drawing of $G$ and $\mathcal A$ is a planar polyline drawing $\Gamma$ of $G$ with an arrangement $A$ of lines so that $\Gamma$ and $A$ are homeomorphic to $G$ and $\mathcal A$. We show that if $\mathcal A$ is stretchable and every edge $e$ either entirely lies on a pseudoline or intersects at most one pseudoline, then $G$ and $\mathcal A$ have a straight-l

On estimating the alphabet size of a discrete random source. (arXiv:1711.07545v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

We are concerned with estimating alphabet size $N$ from a stream of symbols taken uniformly at random from that alphabet. We define and analyze a memory-restricted variant of an algorithm that have been earlier proposed for this purpose. The alphabet size $N$ can be estimated in $O(\sqrt{N})$ time and space by the memory-restricted variant of this algorithm.

Approximation Algorithms for Rectangle Packing Problems (PhD Thesis). (arXiv:1711.07851v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

In rectangle packing problems we are given the task of placing axis-aligned rectangles in a given plane region, so that they do not overlap with each other. In Maximum Weight Independent Set of Rectangles (MWISR), their position is given and we can only select which rectangles to choose, while trying to maximize their total weight. In Strip Packing (SP), we have to pack all the given rectangles in a rectangular region of fixed width, while minimizing its height. In 2-Dimensional Geometric Knapsack (2DGK)

Edge Estimation with Independent Set Oracles. (arXiv:1711.07567v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

We study the problem of estimating the number of edges in a graph with access to only an independent set oracle. Independent set queries draw motivation from group testing and have applications to the complexity of decision versus counting problems. We give two algorithms to estimate the number of edges in an $n$-vertex graph: one that uses only $\mathrm{polylog}(n)$ bipartite independent set queries, and the other one with $\sqrt{n}\cdot \mathrm{polylog}(n)$ independent set queries.

Maximizing Non-monotone/Non-submodular Functions by Multi-objective Evolutionary Algorithms. (arXiv:1711.07214v1 [cs.NE] CROSS LISTED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

Evolutionary algorithms (EAs) are a kind of nature-inspired general-purpose optimization algorithm, and have shown empirically good performance in solving various real-word optimization problems. However, due to the highly randomized and complex behavior, the theoretical analysis of EAs is difficult and is an ongoing challenge, which has attracted a lot of research attentions. During the last two decades, promising results on the running time analysis (one essential theoretical aspect) of EAs have been o

Approximating Geometric Knapsack via L-packings. (arXiv:1711.07710v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

We study the two-dimensional geometric knapsack problem (2DK) in which we are given a set of n axis-aligned rectangular items, each one with an associated profit, and an axis-aligned square knapsack. The goal is to find a (non-overlapping) packing of a maximum profit subset of items inside the knapsack (without rotating items). The best-known polynomial-time approximation factor for this problem (even just in the cardinality case) is (2 + \epsilon) [Jansen and Zhang, SODA 2004]. In this paper, we

Fine-Grained I/O Complexity via Reductions: New lower bounds, faster algorithms, and a time hierarchy. (arXiv:1711.07960v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

This paper initiates the study of I/O algorithms (minimizing cache misses) from the perspective of fine-grained complexity (conditional polynomial lower bounds). Specifically, we aim to answer why sparse graph problems are so hard, and why the Longest Common Subsequence problem gets a savings of a factor of the size of cache times the length of a cache line, but no more. We take the reductions and techniques from complexity and fine-grained complexity and apply them to the I/O model to generate new (cond

Hyperbolic pseudoinverses for kinematics in the Euclidean group. (arXiv:1711.07560v1 [math.MG])

Wednesday, November 22, 01:30 UTC @ cs.CG updates on arXiv.org

The kinematics of a robot manipulator are described in terms of the mapping connecting its joint space and the 6-dimensional Euclidean group of motions $SE(3)$. The associated Jacobian matrices map into its Lie algebra $\mathfrak{se}(3)$, the space of twists describing infinitesimal motion of a rigid body. Control methods generally require knowledge of an inverse for the Jacobian. However for an arm with fewer or greater than six actuated joints or at singularities of the kinematic mapping this breaks do

The Hidden Binary Search Tree:A Balanced Rotation-Free Search Tree in the AVL RAM Model. (arXiv:1711.07746v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

In this paper we generalize the definition of "Search Trees" (ST) to enable reference values other than the key of prior inserted nodes. The idea builds on the assumption an $n$-node AVL (or Red-Black) requires to assure $O(\log_2n)$ worst-case search time, namely, a single comparison between two keys takes constant time. This means the size of each key in bits is fixed to $B=c\log_2 n$ ($c\geq1$) once $n$ is determined, otherwise the $O(1)$-time comparison assumption does not hold. Based on this we calc

$n$-permutability and linear Datalog implies symmetric Datalog. (arXiv:1508.05766v5 [cs.CC] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.CC updates on arXiv.org

We show that if $\mathbb A$ is a core relational structure such that $CSP(\mathbb{A})$ can be solved by a linear Datalog program, and $\mathbb A$ is $n$-permutable for some $n$, then $CSP(\mathbb A)$ can be solved by a symmetric Datalog program (and thus $CSP(\mathbb{A})$ lies in deterministic logspace). At the moment, it is not known for which structures $\mathbb A$ will $CSP(\mathbb{A})$ be solvable by a linear Datalog program. However, once somebody obtains a characterization of linear Datalog, our re

Convergence Results for Neural Networks via Electrodynamics. (arXiv:1702.00458v4 [cs.DS] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

We study whether a depth two neural network can learn another depth two network using gradient descent. Assuming a linear output node, we show that the question of whether gradient descent converges to the target function is equivalent to the following question in electrodynamics: Given $k$ fixed protons in $\mathbb{R}^d,$ and $k$ electrons, each moving due to the attractive force from the protons and repulsive force from the remaining electrons, whether at equilibrium all the electrons will be matched u

Deletion-Robust Submodular Maximization at Scale. (arXiv:1711.07112v2 [cs.LG] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

Can we efficiently extract useful information from a large user-generated dataset while protecting the privacy of the users and/or ensuring fairness in representation. We cast this problem as an instance of a deletion-robust submodular maximization where part of the data may be deleted due to privacy concerns or fairness criteria. We propose the first memory-efficient centralized, streaming, and distributed methods with constant-factor approximation guarantees against any number of adversarial deletions.

Revisiting Connected Vertex Cover: FPT Algorithms and Lossy Kernels. (arXiv:1711.07872v1 [cs.DS])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

The CONNECTED VERTEX COVER problem asks for a vertex cover in a graph that induces a connected subgraph. The problem is known to be fixed-parameter tractable (FPT), and is unlikely to have a polynomial sized kernel (under complexity theoretic assumptions) when parameterized by the solution size. In a recent paper, Lokshtanov et al.[STOC 2017], have shown an $\alpha$-approximate kernel for the problem for every $\alpha > 1$, in the framework of approximate or lossy kernelization. In this work, we exhib

On $P_5$-free Chordal bipartite graphs. (arXiv:1711.07736v1 [cs.DM])

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

A bipartite graph is chordal bipartite if every cycle of length at least 6 has a chord in it. In this paper, we investigate the structure of $P_5$-free chordal bipartite graphs and show that these graphs have a Nested Neighborhood Ordering, a special ordering among its vertices. Further, using this ordering, we present polynomial-time algorithms for classical problems such as Hamiltonian cycle (path) and longest path. Two variants of Hamiltonian path include Steiner path and minimum leaf spanning tree, a

Mixed Integer Programming with Convex/Concave Constraints: Fixed-Parameter Tractability and Applications to Multicovering and Voting. (arXiv:1709.02850v2 [cs.DS] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

A classic result of Lenstra [Math.~Oper.~Res.~1983] says that an integer linear program can be solved in fixed-parameter tractable (FPT) time for the parameter being the number of variables. We extend this result by incorporating non-decreasing piecewise linear convex or concave functions to our (mixed) integer programs. This general technique allows us to establish parameterized complexity of a number of classic computational problems. In particular, we prove that Weighted Set Multicover is in FPT when

A Tight Lower Bound for Counting Hamiltonian Cycles via Matrix Rank. (arXiv:1709.02311v2 [cs.DS] UPDATED)

Wednesday, November 22, 01:30 UTC @ cs.DS updates on arXiv.org

For even $k$, the matchings connectivity matrix $\mathbf{M}_k$ encodes which pairs of perfect matchings on $k$ vertices form a single cycle. Cygan et al. (STOC 2013) showed that the rank of $\mathbf{M}_k$ over $\mathbb{Z}_2$ is $\Theta(\sqrt 2^k)$ and used this to give an $O^*((2+\sqrt{2})^{\mathsf{pw}})$ time algorithm for counting Hamiltonian cycles modulo $2$ on graphs of pathwidth $\mathsf{pw}$. The same authors complemented their algorithm by an essentially tight lower bound under the Strong Exponen

HomePod Delayed Until ‘Early 2018’

Friday, November 17, 16:32 UTC @ Daring Fireball

I just got this statement from an Apple spokesperson: “We can’t wait for people to experience HomePod, Apple’s breakthrough wireless speaker for the home, but we need a little more time before it’s ready for our customers. We’ll start shipping in the US, UK and Australia in early 2018.” I had a feeling this would happen when the iPhone X press briefings came and went without a word about HomePod. It’s a tough miss for Apple — there are

Apple Machine Learning Journal: ‘An On-Device Deep Neural Network for Face Detection’

Thursday, November 16, 22:06 UTC @ Daring Fireball

Apple Machine Learning Journal: We faced several challenges. The deep-learning models need to be shipped as part of the operating system, taking up valuable NAND storage space. They also need to be loaded into RAM and require significant computational time on the GPU and/or CPU. Unlike cloud-based services, whose resources can be dedicated solely to a vision problem, on-device computation must take place while sharing these system resources with other running applications.

Stop Xcode from constantly rebuilding your project because of @IBDesignable

Wednesday, November 15, 14:30 UTC @ Arek Holko

If you use Interface Builder along with @IBDesignable attribute you may have noticed that Xcode sometimes builds your project even though you didn’t trigger a build. This is because it needs to compile views marked with @IBDesignable to be able to render them in Interface Builder. What's problematic is that these builds seem to occur a bit too often. After closer inspection, I managed to notice what happens without having to disassemble Xcode. Xcode

Some of the most important technical advances of the 20th century were enabled by decades of fundamental scientific exploration, whose initial purpose was simply to extend human understanding. When Einstein discovered relativity, he had no idea that one day it would be an important part of modern navigation systems. Such is the story of quantum […] The post The future is quantum appeared first on <

Forking the iPhone

Friday, November 10, 00:35 UTC @ Daring Fireball

Jean-Louis Gassée: What we see is Apple is doing what they do best: Taking chances. They made a risky bet with the iPhone X and covered it with the iPhone 8. The new and improved perception of Apple might come from the realization that both bets are winning, and that the iPhone X is a radically new, as opposed to a merely improved, breed of smartphone — and probably is the start of a new succession of carefully incremented future models. A fork is exactly r

Partial sharing graphs offer a reduction model for the lambda calculus that is optimal in a sense put forward by Jean Jacques Levy.

This result had a chilling effect on the initial wave of excitement over the technology.<

Most species become extinct not because they've evolved in a weird direction but rather because they've failed to evolve fast enough to match changing

Often this is done in multiple layers: Language A is constructed to describe language B which in turn describes the solution. This makes is

Common words that have a technical meaning in math

The phenomenon stems from a cognitive bias known as Dunning-Kruger effect which leads people to not recognize their ineptitude and perceive themselves as superior to their peers. Also, you may have wondered how would you act if you lived in Germany under Hitler, in USSR under Stalin or in North Korea under Kim Jong-un. In a private corner of your mind y

Vladimir Voevodsky, 1966 — 2017

Friday, October 06, 18:41 UTC @ Azimuth

Vladimir Voevodsky died last week. He won the Fields Medal in 2002 for proving the Milnor conjecture in a branch of algebra known as algebraic K-theory. He continued to work on this subject until he helped prove the more general Bloch–Kato conjecture in 2010. Proving these results—which are too technical to easily describe to nonmathematicians!—required […]

Friday Q&A 2017-10-06: Type-Safe User Defaults

Friday, October 06, 12:55 UTC @ NSBlog

It's fun to re-imagine traditional techniques with a Swift twist. I've implemented a type-safe layer on top of the venerable NSUserDefaults, and I'm going to discuss my little library today. Credit/blame for this idea goes to local reader José Vazquez, although he inspired it by accident while talking about something else. (Read More)

Computing nonsimple polygons of minimum perimeter

Friday, October 06, 12:38 UTC @ Journal of Computational Geometry

We consider the Minimum Perimeter Polygon Problem (MP3): for a given set V of points in the plane, find a polygon P with holes that has vertex set V , such that the total boundary length is smallest possible. The MP3 can be considered a natural geometric generalization of the Traveling Salesman Problem (TSP), which asks for a simple polygon with minimum perimeter. Just like the TSP, the MP3 occurs naturally in the context of curve

Maximizing the sum of radii of disjoint balls or disks

Friday, October 06, 12:32 UTC @ Journal of Computational Geometry

Finding nonoverlapping balls with given centers in any metric space, maximizing the sum of radii of the balls, can be expressed as a linear program. Its dual linear program expresses the problem of finding a minimum-weight set of cycles (allowing 2-cycles) covering all vertices in a complete geometric graph. For points in a Euclidean space of any finite dimension $d$, with any convex distance function on this space, this graph can be replaced by a sparse subgraph obeying a separator theorem. This graph s

Is the Textbook Market doomed?

Thursday, October 05, 17:35 UTC @ Computational Complexity

STORY ONE: I always tell my class that its OKAY if they don't have the latest edition of the textbook, and if they can find it a cheap, an earlier edition (often on Amazon, sometimes on e-bay), that's fine. A while back at the beginning of a semester I was curious if the book really did have many cheap editions so I typed in the books name. I found a free pdf copy as the fourth hit. This was NOT on some corner of the dark web. This was easy to find and free. There were a fe

Evolutionary Architecture book published

Xcode 9.1 Improves Display of Fatal Errors

Thursday, October 05, 12:00 UTC @ Swift.org

Swift has language constructs that allow you to specify your program’s expectations. If these expectations are not met at runtime, the program will be terminated. For example, indexing into an array implicitly expresses an expectation that the index is in bounds: // Program will terminate if 'index' less than 0 or greater than 'array.count - 1'. let element

First, Albert Kwon provides an overview of recent systems for secure and private communication. While messaging protocols such as Signal provide privacy guarantees, Albert's selected research papers illustrate what is possible at the cutting edge: more transparent endpoint authentication, better protection of communication metadata, and anonymous broadcasting. These papers marry state-of-the-art cryptography with practical, privacy-preserving protocols, providing a glimpse of what we might expect from tomor

Dictionary and Set Improvements in Swift 4.0

Wednesday, October 04, 12:00 UTC @ Swift.org

In the latest release of Swift, dictionaries and sets gain a number of new methods and initializers that make common tasks easier than ever. Operations like grouping, filtering, and transforming values can now be performed in a single step, letting you write more expressive and efficient code. This post explores these new transformations, using some grocery data for a market as an example. This custom GroceryItem struct, made up of a name and a department, wi

The case of the different jsch 0.1.54 binaries

Wednesday, October 04, 10:48 UTC @ Emilian Bold's blog

As part of the Apache NetBeans IP clearance we are combing through all the code and dependencies. One interesting thing we bumped into was that the jsch 0.1.54 binary JAR we are using has a different hash (and size) than the binary JAR from Maven Central. The old hash is 0D7D8ABA0D11E8CD2F775F47CD3A6CFBF2837DA4, the new one is DA3584329A263616E277E15462B387ADDD1B208D. The binaries are 278,612 bytes vs 280,515 bytes in Mave

Kaizen of Programming

Wednesday, October 04, 09:16 UTC @ 250bpm-blogs

I've started programming early, in 1984 when I was 11 years old. Back then I just had an idea of what the program should do and I did whatever was necessary to get there. After that initial period of pogramming I haven't cared about it too much. I did whatever programming assignments we've got in school and later whatever work I needed to do to feed myself, but that was it. In the spare time I was mostly drinking with artists. That changed in 2004. Back then I star

Accessibility

Tuesday, October 03, 20:18 UTC @ inessential.com

As a young developer I didn’t pay that much attention to accessibility. I figured that most people didn’t need those features, and it was something I could get to later. Plus: adding those features wasn’t easy back in those days. Things have changed. For one thing, supporting accessibility features — at least on Macs and iOS — has gotten much easier. It’s almost delightful with how much you get for free and how easy it is to add what’s missing. Apple deserves a huge amount

IoT neurons go macro, go global with DyBM

Imagine covering the globe with a sheet of artificial, internet-enabled neurons. And these Internet of Things (IoT) neurons could send their local information to other neurons just like the synapses in our brains. For example, a ground temperature neuron at one location gets collected and shared with air quality neurons, and vice versa. This spatio-temporal […] The post IoT neurons go macro, go global with

Yet another year in which you haven’t won a Nobel Prize!

Tuesday, October 03, 07:17 UTC @ Backreaction

“Do you hope to win a Nobel Prize?” asked an elderly man who had come to shake my hand after the lecture. I laughed, but he was serious. Maybe I had been a little too successful explaining how important quantum gravity is. No, I don’t hope to win a Nobel Prize. If that’s what I’d been after, I certainly would have chosen a different field. Condensed matter physics, say, or quantum things. At

Easier Swift Layout Priorities

Monday, October 02, 12:35 UTC @ Use Your Loaf

Working with the priorities of Auto Layout constraints can be a bit of a pain with Swift. You often just want to set a priority that is one more or one less than some other priority. Unfortunately the strong type safety of Swift means you cannot just treat the priority as a number the way you could with Objective-C. Layout Priorities Consider a typical auto layout setup where I have a label and a text field arranged to horizontally fill a view:
