Array-based compact data structures for triangulations: Practical solutions with theoretical guarantees

Wednesday, July 18, 14:23 UTC @ Journal of Computational Geometry

We consider the problem of designing space efficient solutions for representing  triangle meshes. Our main result is a new explicit data structure for compactly representing planar triangulations: if one is allowed to permute input vertices, then a triangulation with $n$ vertices requires at most $4n$ references ($5n$ references if vertex permutations are not allowed). Our solution combines existing techniques from mesh encoding with a novel use of maximal Schnyder woods. Our approach extends to higher gen

Topological drawings of complete graphs and of complete bipartite graphs have been studied extensively in the context of crossing number problems. We consider a natural class of simple topological drawings of {\em complete bipartite} graphs, in which we require that one side of the vertex set bipartition lies on the outer boundary of the drawing.

Optimization of the n-dimensional sliding window inter-channel correlation algorithm for multi-core architecture. (arXiv:1807.06507v1 [cs.DS])

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

Calculating the correlation in a sliding window is a common method of statistical evaluation of the interconnect between two sets of data. And although the calculation of a single correlation coefficient is not resource-intensive and algorithmically complex, sequential computation in a large number of windows on large data sets can take quite a long time. In this case, each value in the data, falling into different windows, will be processed many times, increasing the complexity of the algorithm and the

Tracking the $\ell_2$ Norm with Constant Update Time. (arXiv:1807.06479v1 [cs.DS])

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

The $\ell_2$ tracking problem is the task of obtaining a streaming algorithm that, given access to a stream of items $a_1,a_2,a_3,\ldots$ from a universe $[n]$, outputs at each time $t$ an estimate to the $\ell_2$ norm of the frequency vector $f^{(t)}\in \mathbb{R}^n$ (where $f^{(t)}_i$ is the number of occurrences of item $i$ in the stream up to time $t$). The previous work [Braverman-Chestnut-Ivkin-Nelson-Wang-Woodruff, FOCS 2017] gave an streaming algorithm with (the optimal) space using $O(\epsilon^{

A universal-algebraic proof of the complexity dichotomy for Monotone Monadic SNP. (arXiv:1802.03255v3 [cs.CC] UPDATED)

Wednesday, July 18, 01:30 UTC @ cs.CC updates on arXiv.org

The logic MMSNP is a restricted fragment of existential second-order logic which allows to express many interesting queries in graph theory and finite model theory. The logic was introduced by Feder and Vardi who showed that every MMSNP sentence is computationally equivalent to a finite-domain constraint satisfaction problem (CSP); the involved probabilistic reductions were derandomized by Kun using explicit constructions of expander structures. We present a new proof of the reduction to finite-domain CS

Deterministic Document Exchange Protocols, and Almost Optimal Binary Codes for Edit Errors. (arXiv:1804.05776v4 [cs.DS] UPDATED)

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

We study two basic problems regarding edit error, i.e. document exchange and error correcting codes for edit errors (insdel codes). For message length $n$ and edit error upper bound $k$, it is known that in both problems the optimal sketch size or the optimal number of redundant bits is $\Theta(k \log \frac{n}{k})$. However, known constructions are far from achieving these bounds. We significantly improve previous results on both problems. For document exchange, we give an efficient deterministic

Generation of planar tensegrity structures through cellular multiplication. (arXiv:1807.06279v1 [cs.CE])

Tensegrity structures are frameworks in a stable self-equilibrated prestress state that have been applied in various fields in science and engineering. Research into tensegrity structures has resulted in reliable techniques for their form finding and analysis. However, most techniques address topology and form separately. This paper presents a bio-inspired approach for the combined topology identification and form finding of planar tensegrity structures. Tensegrity structures are generated using tensegri

On Computing Centroids According to the $p$-Norms of Hamming Distance Vectors. (arXiv:1807.06469v1 [cs.CC])

Wednesday, July 18, 01:30 UTC @ cs.CC updates on arXiv.org

In this paper we consider the \textsc{$p$-Norm Hamming Centroid} problem which asks to determine whether some given binary strings have a centroid with a bound on the $p$\nobreakdash-norm of its Hamming distances to the strings. Specifically, given a set of strings $S$ and a real $k$, we consider the problem of determining whether there exists a string $s^*$ with $\big(\sum_{s \in S}d^p(s^*,s)\big)^{1/p} \leq k$, where $d(,)$ denotes the Hamming distance metric. This problem has important applications in

Faster Algorithms via Waring Decompositions. (arXiv:1807.06194v1 [cs.DS])

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

We show that decompositions of certain polynomials as sums of powers of linear forms yield faster algorithms for some algebraic problems. Such a decomposition is known as a Waring decomposition. Our results are: 1. We give a black-box algorithm for computing the sum of the coefficients of the degree-k multilinear monomials in a polynomial over a field of characteristic zero. Our algorithm runs in time $O^*(n^{k/2})$ and space $poly(n)$. This solves an open problem of Koutis and Williams [1].

Sparsifying Distributed Algorithms with Ramifications in Massively Parallel Computation and Centralized Local Computation. (arXiv:1807.06251v1 [cs.DS])

We introduce a method for sparsifying distributed algorithms and exhibit how it leads to improvements that go past known barriers in two algorithmic settings of large-scale graph processing: Massively Parallel Computation (MPC), and Local Computation Algorithms (LCA). - MPC with Strongly Sublinear Memory: Recently, there has been growing interest in obtaining MPC algorithms that are faster than their classic $O(\log n)$-round parallel counterparts for problems such as MIS, Maximal Matching, 2-App

Using statistical encoding to achieve tree succinctness never seen before. (arXiv:1807.06359v1 [cs.DS])

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

We propose a new succinct representation of labeled trees which represents a tree T using |T|H_k(T) number of bits (plus some smaller order terms), where |T|H_k(T) denotes the k-th order (tree label) entropy, as defined by Ferragina at al. 2005. Our representation employs a new, simple method of partitioning the tree, which preserves both tree shape and node degrees. Previously, the only representation that used |T|H_k(T) bits was based on XBWT, a transformation that linearizes tree labels into a single

Local Rejection Sampling with Soft Filters. (arXiv:1807.06481v1 [cs.DS])

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

We study a new LLL-like framework for rejection sampling, which naturally generalizes the variable-framework for the Lov\'asz local lemma (LLL) and the LLL-based Partial Rejection Sampling of Guo, Jerrum and Liu [STOC'17]. In this new framework, the occurrence of a bad event is biased by the current evaluation of variables, rather than being determined by them as in the standard setting of LLL. Such generalization allows us to model rejection samplings with soft filters. We give a generic algorithm, call

Polynomial Norms. (arXiv:1704.07462v3 [math.OC] UPDATED)

Wednesday, July 18, 01:30 UTC @ cs.CC updates on arXiv.org

In this paper, we study polynomial norms, i.e. norms that are the $d^{\text{th}}$ root of a degree-$d$ homogeneous polynomial $f$. We first show that a necessary and sufficient condition for $f^{1/d}$ to be a norm is for $f$ to be strictly convex, or equivalently, convex and positive definite. Though not all norms come from $d^{\text{th}}$ roots of polynomials, we prove that any norm can be approximated arbitrarily well by a polynomial norm. We then investigate the computational problem of testing whethe

Classical lower bounds from quantum upper bounds. (arXiv:1807.06256v1 [quant-ph])

Wednesday, July 18, 01:30 UTC @ cs.CC updates on arXiv.org

We prove lower bounds on complexity measures, such as the approximate degree of a Boolean function and the approximate rank of a Boolean matrix, using quantum arguments. We prove these lower bounds using a quantum query algorithm for the combinatorial group testing problem. We show that for any function f, the approximate degree of computing the OR of n copies of f is Omega(sqrt{n}) times the approximate degree of f, which is optimal. No such general result was known prior to our work, and even t

Computing the Homology of Semialgebraic Sets I: Lax Formulas. (arXiv:1807.06435v1 [cs.CG])

We describe and analyze an algorithm for computing the homology (Betti numbers and torsion coefficients) of closed semialgebraic sets given by Boolean formulas without negations over lax polynomial inequalities. The algorithm works in weak exponential time. This means that outside a subset of data having exponentially small measure, the cost of the algorithm is single exponential in the size of the data. All previous algorithms solving this problem have doubly exponential complexity (and this is

Counting higher order tangencies for plane curves. (arXiv:1807.06580v1 [math.CO])

The main focus is the query complexity of {\sc Hitting Set}. In doing so, we use an oracle known as \bis{} introduced by Beame et al.~\cite{BeameHRRS18} and its generalizations to hypergraphs. The query models considered are the \gpis{} and \gpise{} oracles : (i) the \gpis{} oracle takes as input $d$ pairwise disjoin

Colouring Square-Free Graphs without Long Induced Paths. (arXiv:1805.08270v1 [math.CO] CROSS LISTED)

Wednesday, July 18, 01:30 UTC @ cs.DS updates on arXiv.org

The complexity of {\sc Colouring} is fully understood for $H$-free graphs, but there are still major complexity gaps if two induced subgraphs $H_1$ and $H_2$ are forbidden. Let $H_1$ be the $s$-vertex cycle $C_s$ and $H_2$ be the $t$-vertex path $P_t$. We show that {\sc Colouring} is polynomial-time solvable for $s=4$ and $t\leq 6$, strengthening several known results. Our main approach is to initiate a study into the boundedness of the clique-width of atoms (graphs with no clique cutset) of a hereditary

How many copies of a parallelepiped are needed to ensure that for every point in the parallelepiped a copy of each other point exists, such that the distance between them equals the distance of the pair of points when the opposite sites of the parallelepiped are identified? This question is answered in Euclidean space by constructing the smallest domain that fulfills the above condition. We also describe how to obtain all primitive cells of a lattice (i.e., closures of fundamental domains) that realise t

Hierarchical Growth is Necessary and (Sometimes) Sufficient to Self-Assemble Discrete Self-Similar Fractals. (arXiv:1807.04831v2 [cs.ET] UPDATED)

In this paper, we prove that in the abstract Tile Assembly Model (aTAM), an accretion-based model which only allows for a single tile to attach to a growing assembly at each step, there are no tile assembly systems capable of self-assembling the discrete self-similar fractals known as the "H" and "U" fractals. We then show that in a related model which allows for hierarchical self-assembly, the 2-Handed Assembly Model (2HAM), there does exist a tile assembly systems which self-assembles the "U" fractal a

Optimal Quasi-Gray Codes: The Alphabet Matters. (arXiv:1712.01834v2 [cs.IT] UPDATED)

A quasi-Gray code of dimension $n$ and length $\ell$ over an alphabet $\Sigma$ is a sequence of distinct words $w_1,w_2,\dots,w_\ell$ from $\Sigma^n$ such that any two consecutive words differ in at most $c$ coordinates, for some fixed constant $c>0$. In this paper we are interested in the read and write complexity of quasi-Gray codes in the bit-probe model, where we measure the number of symbols read and written in order to transform any word $w_i$ into its successor $w_{i+1}$.

It is a longstanding open problem to construct an explicit 1-factorization of the bipartite Kneser graph $H(n,k)$, which contains as vertices all $k$-element and $(n-k)$-element subsets of $[n]:=\{1,\ldots,n\}$ and an edge between any two vertices when one is a subset of the other. We revisit two classic constructions for the case $n=2k+1$ and give a new construction for another case. More specifically, we first revisit the case $n=2k+1$, in which there are two well-known 1-factorizations called

The Space Complexity of Personalized PageRank and Shortest Path Labeling Schemes. (arXiv:1712.08709v2 [cs.SI] UPDATED)

In a labeling scheme, each vertex is assigned a \emph{label vector}; To answer a query between two vertices, only the labels of the two vertices may be accessed.

Near-optimal Bootstrapping of Hitting Sets for Algebraic Circuits. (arXiv:1807.06323v1 [cs.CC])

Wednesday, July 18, 01:30 UTC @ cs.CC updates on arXiv.org

The classical lemma of Ore-DeMillo-Lipton-Schwartz-Zippel states that any nonzero polynomial $f(x_1,\ldots, x_n)$ of degree at most $s$ will evaluate to a nonzero value at some point on a grid $S^n \subseteq \mathbb{F}^n$ with $|S| > s$. Thus, there is a deterministic polynomial identity test (PIT) for all degree-$s$ size-$s$ algebraic circuits in $n$ variables that runs in time $\mathrm{poly}(s) \cdot (s+1)^n$.

We investigate distribution testing with access to non-adaptive conditional samples. In the conditional sampling model, the algorithm is given the following access to a distribution: it submits a query set $S$ to an oracle, which returns a sample from the distribution conditioned on being from $S$. In the non-adaptive setting, all query sets must be specified in advance of viewing the outcomes.

Markov chain methods are remarkably successful in computational physics, machine learning, and combinatorial optimization. The cost of such methods often reduces to the mixing time, i.e. \ the time required to reach the steady state of the Markov chain, which scales as $\delta^{-1}$, the inverse of the spectral gap. It has long been conjectured that quantum computers offer nearly generic quadratic improvements for mixing problems. However, except in special cases, quantum algorithms achieve a run-time of

Tracy Jan, reporting earlier this month for The Washington Post: Shoppers can purchase Amazon.com merchandise displaying symbols of white supremacy, such as a swastika necklace, a baby onesie with a burning cross, and a child’s backpack featuring a neo-Nazi meme, all in contradiction of the retail giant’s policy against selling products that promote hatred, according to a new report from two watchdog groups.

‘The Axis Is Constructive-Destructive’

Tuesday, July 17, 20:10 UTC @ Daring Fireball

Steve Jobs, in a 2010 conversation with Rupert Murdoch, in which Jobs told Murdoch he was “blowing it with Fox News”: “The axis today is not liberal and conservative, the axis is constructive-destructive, and you’ve cast your lot with the destructive people. Fox has become an incredibly destructive force in our society. You can be better, and this is going to be your legacy if you’re not careful.” I thought this was interesting in light of

MacOS 10.14 Mojave Removes Subpixel Anti-Aliasing

Tuesday, July 17, 19:41 UTC @ Daring Fireball

I was a huge fan of sub-pixel anti-aliasing back in the day (and in fact still have it enabled on 10.13), but it matters far more on non-retina displays than retina ones. I think it’s proper for Apple to focus on retina displays — and iOS has never supported sub-pixel anti-aliasing, which I can only guess factored into this decision with the introduction of UIKit apps running on MacOS — but they’re still selling the non-retina MacBook Air. I won’t issue a f

Third-Generation MacBook Pro Keyboards Have a Protective Silicone Barrier

We’re in the middle of tearing down the newest MacBook Pro, but we’re too excited to hold this particular bit of news back: Apple has cocooned their butterfly switches in a thin, silicone barrier.

Popular Science: ‘Do You Really Need to Properly Eject a USB Drive Before Yanking It Out?’

Rob Verger, writing for Popular Science: Pull a USB flash drive out of your Mac without first clicking to eject it, and you’ll get a stern, shameful warning: “Disk Not Ejected Properly.” But do you really need to eject a thumb drive the right way? Probably not. Just wait for it to finish copying your data, give it a few seconds, then yank. To be on the cautious side, be more conservative with external hard drives, especially the old ones that actually spin.

Models should be not only good, but also interpretable, yet the task of interpretation appears underspecified.

Despite this ambiguity, many authors proclaim

Verifying PostgreSQL backups made easier with new open-source tool

Wednesday, July 11, 14:00 UTC @ Google Cloud Platform Blog

By Brett Hesterberg, Product Manager and Alexis Guajardo, Senior Software Engineer When was the last time you verified a database backup? If that question causes you to break into a cold sweat, rest assured you’re not alone. Verifying backups should be a common practice, but it often isn’t. This can be an issue if there’s a disaster or—as is more likely at most companies—if someone makes a mistake when deploying database changes.

Friday Q&A 2018-06-29: Debugging with C-Reduce

Friday, June 29, 13:35 UTC @ NSBlog

Debugging a complex problem is tough, and it can be especially difficult when it's not obvious which chunk of code is responsible. It's common to attempt to produce a reduced test case in order to narrow it down. It's tedious to do this manually, but it's also the sort of thing computers are really good at. C-Reduce is a program which automatically takes programs and pares them down to produce a reduced test case. Let's take a look at how to use it.

Improved time-space trade-offs for computing Voronoi diagrams

Friday, June 29, 10:52 UTC @ Journal of Computational Geometry

Let $P$ be a planar set of $n$ sites in general position. For $k \in \{1, \dots, n-1\}$, the Voronoi diagram of order $k$ for $P$ is obtained by subdividing the plane into cells such that points in the same cell have the same set of nearest $k$ neighbors in $P$. The (nearest site) Voronoi diagram (NVD) and the farthest site Voronoi diagram (FVD) are the particular cases of $k=1$ and $k=n-1$, respectively. For any given $K \in \{1, \dots, n-1\}$, the family of all higher-order Voronoi diagrams of order $k

On the geodesic centers of polygonal domains

Thursday, June 28, 06:45 UTC @ Journal of Computational Geometry

In this paper, we study the problem of computing Euclidean geodesic centers of a polygonal domain $P$ with a total of $n$ vertices. We discover many interesting observations. We give a necessary condition for a point being a geodesic center. We show that there is at most one geodesic center among all points of $P$ that have topologically-equivalent shortest path maps. This implies that the total number of geodesic centers is bounded by the combinatorial size of the shortest path map equivalence decom

I have given the following answers for years; however, I post this and will use your comments as a sanity check. In fact, I suspect I am wrong on some points. 1) IF SAT was in P then something very clever was done. Even if its n^{100} it was very clever. That cleverness will almost surely result in other be
