Distributed Symmetry Breaking in Sampling (Optimal Distributed Randomly Coloring with Fewer Colors). (arXiv:1802.06953v3 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

We examine the problem of almost-uniform sampling proper $q$-colorings of a graph whose maximum degree is $\Delta$. A famous result, discovered independently by Jerrum(1995) and Salas and Sokal(1997), is that, assuming $q > (2+\delta) \Delta$, the Glauber dynamics (a.k.a. single-site dynamics) for this problem has mixing time $O(n \log n)$, where $n$ is the number of vertices, and thus provides a nearly linear time sampling algorithm for this problem. A natural question is the extent to which this alg

As-exact-as-possible repair of unprintable STL files. (arXiv:1605.07829v3 [cs.GR] UPDATED)

Friday, June 22, 01:30 UTC @ cs.CG updates on arXiv.org

Purpose: The class of models that can be represented by STL files is larger than the class of models that can be printed using additive manufacturing technologies. Stated differently, there exist well-formed STL files that cannot be printed. In this paper such a gap is formalized and a fully automatic procedure is described to turn any such file into a printable model. Approach: Based on well-established concepts from combinatorial topology, we provide an unambiguous description of all the mathem

Deterministic parallel algorithms for bilinear objective functions. (arXiv:1711.08494v3 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

Many randomized algorithms can be derandomized efficiently using either the method of conditional expectations or probability spaces with low independence. A series of papers, beginning with work by Luby (1988), showed that in many cases these techniques can be combined to give deterministic parallel (NC) algorithms for a variety of combinatorial optimization problems, with low time- and processor-complexity. We extend and generalize a technique of Luby for efficiently handling bilinear objective

Enumerable Distributions, Randomness, Dependence. (arXiv:1208.2955v12 [cs.CC] UPDATED)

Friday, June 22, 01:30 UTC @ cs.CC updates on arXiv.org

Kolmogorov-Martin-Lof randomness concept is extended from computable to enumerable distributions. This allows definitions of various other properties, such as mutual information in infinite sequences. Enumerable distributions (as well as distributions faced in some finite multi-party settings) are SEMIMEASURES, not measures; handling those requires some care.

A connection between String Covers and Cover Deterministic Finite Tree Automata Minimization. (arXiv:1806.08232v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

Data compression plays a crucial part in the cloud based systems of today. One the fundaments of compression is quasi-periodicity, for which there are several models. We build upon the most popular quasi-periodicity model for strings, i.e., covers, generalizing it to trees. We introduce a new type of cover automata, which we call \textbf{D}eterministic \textbf{T}ree \textbf{A}utomata. Then, we formulate a cover problem on these DTA and study its complexity, in both sequential and parallel setting

Hardness and algorithmic results for the approximate cover problem. (arXiv:1806.08135v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

In CPM 2017, Amir et al. introduce a problem, named \emph{approximate string cover} (\textbf{ACP}), motivated by many aplications including coding and automata theory, formal language theory, combinatorics and molecular biology. A \emph{cover} of a string $T$ is a string $C$ for which every letter of $T$ lies within some occurrence of $C$. The input of the \textbf{ACP} problem consists of a string $T$ and an integer $m$ (less than the length of $T$), and the goal is to find a string $C$ of length $m$ tha

Energy-Efficient Scheduling: Classification, Bounds, and Algorithms. (arXiv:1609.06430v2 [cs.DC] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

The problem of attaining energy efficiency in distributed systems is of importance, but a general, non-domain-specific theory of energy-minimal scheduling is far from developed. In this paper, we classify the problems of energy-minimal scheduling and present theoretical foundations of the same. We derive results concerning energy-minimal scheduling of independent jobs in a distributed system with functionally similar machines with different working and idle power ratings. The machines considered in our s

Topological Data Analysis Made Easy with the Topology ToolKit. (arXiv:1806.08126v1 [cs.DM])

Friday, June 22, 01:30 UTC @ cs.CG updates on arXiv.org

This tutorial presents topological methods for the analysis and visualization of scientific data from a user's perspective, with the Topology ToolKit (TTK), a recently released open-source library for topological data analysis. Topological methods have gained considerably in popularity and maturity over the last twenty years and success stories of established methods have been documented in a wide range of applications (combustion, chemistry, astrophysics, material sciences, etc.) with both acquired and

Enumeration in Incremental FPT-Time. (arXiv:1804.07799v2 [cs.LO] UPDATED)

Friday, June 22, 01:30 UTC @ cs.CC updates on arXiv.org

In this paper, we study the relationship of parametrised enumeration complexity classes defined by Creignou et al. (MFCS 2013). Specifically, we introduce two hierarchies (IncFPTa and CapIncFPTa) of enumeration complexity classes for incremental fpt-time in terms of exponent slices and show how they interleave. Furthermore, we define several parametrised function classes and, in particular, introduce the parametrised counterpart of the class of nondeterministic multivalued functions with values that are

A Polynomial-Time Algorithm for $(2-2/k)$-stable Instances of the k-terminal cut Problem. (arXiv:1806.06091v2 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

The $k$-terminal cut problem is defined on an edge-weighted graph with $k$ distinct vertices called "terminals." The goal is to remove a minimum weight collection of edges from the graph such that there is no path between any pair of terminals. The $k$-terminal cut problem is known to be NP-hard. There has been interest in determining special classes of graphs for which $k$-terminal cut can be solved in polynomial time. One special class of graphs is the class of $\gamma$-stable graphs, a notion

A Unified PTAS for Prize Collecting TSP and Steiner Tree Problem in Doubling Metrics. (arXiv:1710.07774v2 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

We present a unified polynomial-time approximation scheme (PTAS) for the prize collecting traveling salesman problem (PCTSP) and the prize collecting Steiner tree problem (PCSTP) in doubling metrics. Given a metric space and a penalty function on a subset of points known as terminals, a solution is a subgraph on points in the metric space, whose cost is the weight of its edges plus the penalty due to terminals not covered by the subgraph. Under our unified framework, the solution subgraph needs to be Eul

An improved analysis of the M\"omke-Svensson algorithm for graph-TSP on subquartic graphs. (arXiv:1407.2524v2 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

M\"omke and Svensson presented a beautiful new approach for the traveling salesman problem on a graph metric (graph-TSP), which yields a $4/3$-approximation guarantee on subcubic graphs as well as a substantial improvement over the $3/2$-approximation guarantee of Christofides' algorithm on general graphs. The crux of their approach is to compute an upper bound on the minimum cost of a circulation in a particular network, $C(G,T)$, where $G$ is the input graph and $T$ is a carefully chosen spanning tree.

An output-sensitive algorithm for the minimization of 2-dimensional String Covers. (arXiv:1806.08131v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

String covers are a powerful tool for analyzing the quasi-periodicity of 1-dimensional data and find applications in automata theory, computational biology, coding and the analysis of transactional data. A \emph{cover} of a string $T$ is a string $C$ for which every letter of $T$ lies within some occurrence of $C$. String covers have been generalized in many ways, leading to \emph{k-covers}, \emph{$\lambda$-covers}, \emph{approximate covers} and were studied in different contexts such as \emph{indetermin

Cycles to the Rescue! Novel Constraints to Compute Maximum Planar Subgraphs Fast. (arXiv:1806.08283v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

The NP-hard Maximum Planar Subgraph problem asks for a planar subgraph $H$ of a given graph $G$ such that $H$ has maximum edge cardinality. For more than two decades, the only known non-trivial exact algorithm was based on integer linear programming and Kuratowski's famous planarity criterion. We build upon this approach and present new constraint classes, together with a lifting of the polyhedron, to obtain provably stronger LP-relaxations, and in turn faster algorithms in practice. The new constraints

Homomorphism Extension. (arXiv:1802.08656v2 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

We define the Homomorphism Extension (HomExt) problem: given a group $G$, a subgroup $M \leq G$ and a homomorphism $\varphi: M \to H$, decide whether or not there exists a homomorphism $\widetilde{\varphi}: G\to H$ extending $\varphi$, i.e., $\widetilde{\varphi}|_M = \varphi$. This problem arose in the context of list-decoding homomorphism codes but is also of independent interest, both as a problem in computational group theory and as a new and natural problem in NP of unsettled complexity status.

Instance-Optimality in the Noisy Value-and Comparison-Model --- Accept, Accept, Strong Accept: Which Papers get in?. (arXiv:1806.08182v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

Motivated by crowdsourced computation, peer-grading, and recommendation systems, Braver- man et al. [STOC'16] recently studied the query and round complexity of classic and popu- lar problems such as finding the maximum (max), finding all elements above a certain value (threshold-v) or computing the top-k elements of an array (top-k) in a noisy environment. An illustrating example is the task of selecting papers for a conference. This task is challenging due the crowdsourcing-nature of peer reviews: (1)

Shortest Reconfiguration Sequence for Sliding Tokens on Spiders. (arXiv:1806.08291v1 [cs.DS])

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

Suppose that two independent sets $I$ and $J$ of a graph with $\vert I \vert = \vert J \vert$ are given, and a token is placed on each vertex in $I$. The Sliding Token problem is to determine whether there exists a sequence of independent sets which transforms $I$ into $J$ so that each independent set in the sequence results from the previous one by sliding exactly one token along an edge in the graph. It is one of the representative reconfiguration problems that attract the attention from the viewpoint

Pairing heaps: the forward variant. (arXiv:1709.01152v2 [cs.DS] UPDATED)

Friday, June 22, 01:30 UTC @ cs.DS updates on arXiv.org

The pairing heap is a classical heap data structure introduced in 1986 by Fredman, Sedgewick, Sleator, and Tarjan. It is remarkable both for its simplicity and for its excellent performance in practice. The "magic" of pairing heaps lies in the restructuring that happens after the deletion of the smallest item. The resulting collection of trees is consolidated in two rounds: a left-to-right pairing round, followed by a right-to-left accumulation round. Fredman et al. showed, via an elegant correspondence

Kotoba: The Best iOS Dictionary App You’ve Never Heard Of

Tuesday, June 19, 23:07 UTC @ Daring Fireball

I love dictionaries. For as long as I can remember, I’ve made a habit of looking up every single word I encounter that I don’t know or am even unsure about. The fact that MacOS and iOS have built-in dictionaries that you can invoke via a contextual menu item is one of my favorite features of both OSes. Part of that is the extraordinary convenience, and part is that both systems use the same excellent source: New Oxford American Dictionary. (MacOS also includes the excellent

Oppo’s Find X Ditches the Notch for Pop-Up Cameras

The pop-up cameras are certainly an original idea (but not a good one), but it’s jaw-dropping how much Oppo (apparently pronounced “OH-poe”) made their “Color OS” Android skin look like iOS, from the home screen to the camera app. This looks nothing like stock Android as seen on a Pixel. ★

Elon Musk in Company-Wide Email: Tesla Employee Conducted ‘Extensive and Damaging Sabotage’

Elon Musk, in a company-wide email: The full extent of his actions are not yet clear, but what he has admitted to so far is pretty bad. His stated motivation is that he wanted a promotion that he did not receive. In light of these actions, not promoting him was definitely the right move. However, there may be considerably more to this situation than meets the eye, so the investigation will continue in depth this week. We need to figure out if he was acting alone or with others

How Will Apple Sell Its Original Video Content?

Apple currently allows free trials in two forms: if you sell subscriptions, you can give customers a free month to try the app; and, you can give your app away free, and offer a free In-App Purchase (IAP) to unlock all features for a fix

Gordon Gottsegen, reporting for CNet: Even though the iPhone 3GS will be sold as “brand new,” don’t expect it to work the same as a recently released iPhone. The iPhone 3GS was discontinued back in 2012, and it only runs iOS 6. As a result, many apps (and even iMessages) won’t work on the phone. The iPhone predates Lightning cables, too, so you’ll be stuck using an old-school 30-pin connector. Still, SK Telink is selling the iPhone 3GS for o

Relative error in the central limit theorem

Tuesday, June 05, 00:52 UTC @ John D. Cook

If you average a large number independent versions of the same random variable, the central limit theorem says the average will be approximately normal. That is the absolute error in approximating the density of the average by the density of a normal random variable will be small. (Terms and conditions apply. See notes here.) But […]

Computing extreme normal tail probabilities

Friday, June 01, 15:28 UTC @ John D. Cook

Let me say up front that relying on the normal distribution as an accurate model of extreme events is foolish under most circumstances.

Workload Frequency Scaling Law - Derivation and Verification

Thursday, May 24, 17:48 UTC @ ACM Queue - All Queue Content

This article presents equations that relate to workload utilization scaling at a per-DVFS subsystem level. A relation between frequency, utilization, and scale factor (which itself varies with frequency) is established. The verification of these equations turns out to be tricky, since inherent to workload, the utilization also varies seemingly in an unspecified manner at the granularity of governance samples. Thus, a novel approach called histogram ridge trace is applied. Quantifying the scaling impact is c

10 best rational approximations for pi

It’s easy to create rational approximations for π. Every time you write down π to a few decimal places, that’s a rational approximation. For example, 3.14 = 314/100. But that’s not the best approximation. Think of the denominator of your fraction as something you have to buy. If you have enough budget to buy a three-digit […]

Love them or hate them, Storyboards are used in many iOS projects. In this week’s Swift Tip, we look at a simple way to make them more robust. When you present a new view controller using Storyboards, it’s usually a multi-step process: first, the segue is triggered, and at a later step, you configure the segue. This makes it easy to miss configuration code. For example, in the code below, we set the two properties that the PlayViewController needs:

Christophe Rhodes: algorithms and data structures term2

Tuesday, May 08, 19:17 UTC @ Planet Lisp

I presented some of the work on teaching algorithms and data structures at the 2018 European Lisp Symposium Given that I wanted to go to the symposium (and I'm glad I did!), the most economical method for going was if I presented research work - because then there was a reasonable chance that my employer wo

Swift Tip: First Class Functions

Tuesday, May 08, 00:00 UTC @ objc.io

Since the first public release of Swift (4 years ago in June!), there’s been much debate about whether Swift is a functional language. Rather than engaging in that discussion, we believe it’s more productive to explore useful techniques from functional programming that you can use today. In Episode 19 of Swift Talk, we looked into replacing NSSortDescriptor with a function:

Planet Nine makes some KBOs go wild

Monday, May 07, 20:57 UTC @ The Search for Planet Nine

Hi, everyone! I’m Tali, an undergrad at the University of Michigan. Last summer, I worked on a Planet Nine project with Konstantin and Mike, and although we didn’t find Planet Nine (yet!), we did look further into the stability of objects in the presence of Planet Nine. Turns out, not everything is stable! I

Internal Typealias Promotion

Monday, May 07, 20:00 UTC @ Indie Stack

In some scenarios it might be useful to declare a typealias internally to a module, to make it easier to implement the functionality of the module itself, but less useful to export that typealias to clients of the module. For example, consider an image manipulation framework that can work with NSImage or UIImage instances, depending … Continue reading Internal Typealias Promotion

Every Silver Lining Has a Cloud

Monday, May 07, 14:49 UTC @ ACM Queue - All Queue Content

Clearly, your management has never heard the phrase, "You get what you pay for." Or perhaps they heard it and didn't realize it applied to them. The savings in cloud computing comes at the expense of a loss of control over your systems, which is summed up best in the popular nerd sticker that says, "The Cloud is Just Other People's Computers." Some providers now have something called Metal-as-a-Service, which I really think ought to mean that an '80s metal band shows up at your office, plays a gig, smashes

Talking to AI – Where natural language falls short

Monday, May 07, 12:00 UTC @ IBM Blog Research

User interfaces to artificial intelligence (AI) applications are increasingly using natural language. But while today’s chatbots and AI agents can recognize natural language, like English or Spanish, they still cannot engage with humans in natural conversation. For example, virtual agents often give away the punchline of their own jokes. Today’s Chatbot 1 Human: Tell me […] The post

Success at Apache: Dip into the Apache Way

Monday, May 07, 10:59 UTC @ The Apache Software Foundation Blog

by Nick Couchman Like other recent contributors to this blog, I am not a developer by trade. My day job is as a Linux Systems Engineer and team manager, and, truth be told, my programming skills are not something I would rely on to make a living. Despite these facts, I've found something beyond acceptance in being a part of the Apache Guacamole project: mentoring. Most of my experience with The Apache Software Foundation (ASF) ha

Dealing with Dates

Monday, May 07, 00:00 UTC @ The Syndicate

Introduction “What time is it?” has been an important question to humans for quite some time. For most of history, we only cared what time it was here: When will it get dark? When will it get light? When will this woolly mammoth fall into my cunning spike trap? Then, things got more complicated. I’ve sailed halfway around the world, and the people here think it’s the year 4567, not 1800, what’s up with that? I have a teleconference next week with my client,

Disentanglement of Latent Factors of Variation with Deep Learning

Friday, May 04, 15:18 UTC @ IBM Blog Research

The ability to infer abstract high-level concepts from raw sensory inputs is a key part of human intelligence. Developing models that recapitulate this ability is an important goal in AI research. A fundamental challenge in this respect is disentangling the underlying factors of variation that give rise to the observed data. For example, factors of […] The post Disentanglement of Latent Factors

A few weeks ago, I attended the 2018 European Lisp Symposium. If you were at the 2017 iteration, you might (as I do) have been left with an abiding image of greyness. That was not at all to fault the location (Brussels) or the organization (co-located with ) of the symposium; however, the weather

Drawing planar graphs with many collinear vertices

Thursday, May 03, 13:30 UTC @ Journal of Computational Geometry

Consider the following problem: Given a planar graph $G$, what is the maximum number $p$ such that $G$ has a planar straight-line drawing with $p$ collinear vertices? This problem resides at the core of several graph drawing problems, including universal point subsets, untangling, and column planarity. The following results are known for it: Every $n$-vertex planar graph has a planar straight-line drawing with $\Omega(\sqrt{n})$ collinear vertices; for every $n$, there is an $n$-vertex planar graph whose

Musings on Social Capital

I come from Slovakia. Despite being a programer, I grew up and lived in the artist community of Bratislava. Nowadays, though, I am living in Switzerland. I knew that some of the artists from my home city have established ateliers in the old thread factory. Actually, I've spent quite a few days on the premises. But since I moved away, I've heard that the artists haven't managed to make a deal with the owner of the building and that they had to move away. I've also h
