Fractional Problems: 2.1-colorable, 2.8-SAT

Monday, August 20, 04:09 UTC @ Computational Complexity

Some graphs are 2-colorable, some graphs are 3-colorable, some graphs are...Does it make sense to say that a graph is 2.1-colorable? It does!(Source_ Factional Graph Theory by Schneinerman and Ullman-- I saw a talk on this by Jim Propp a long time ago.) Def 1: A graph is (a,b)-colorable (with a \le b) if you can assign to every vertex a set of a numbers from {1,...,b} such that if u and v are adjacent then the set of numbers are disjoint. Note that k-colorable is (1,k)-colorable. Let chi_b(G) b

Decremental Single-Source Shortest Paths on Undirected Graphs in Near-Linear Total Update Time. (arXiv:1512.08148v2 [cs.DS] UPDATED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

In the decremental single-source shortest paths (SSSP) problem we want to maintain the distances between a given source node $s$ and every other node in an $n$-node $m$-edge graph $G$ undergoing edge deletions. While its static counterpart can be solved in near-linear time, this decremental problem is much more challenging even in the undirected unweighted case. In this case, the classic $O(mn)$ total update time of Even and Shiloach [JACM 1981] has been the fastest known algorithm for three decades. At

Estimating graph parameters with random walks. (arXiv:1709.00869v2 [math.ST] UPDATED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

An algorithm observes the trajectories of random walks over an unknown graph $G$, starting from the same vertex $x$, as well as the degrees along the trajectories. For all finite connected graphs, one can estimate the number of edges $m$ up to a bounded factor in $O\left(t_{\mathrm{rel}}^{3/4}\sqrt{m/d}\right)$ steps, where $t_{\mathrm{rel}}$ is the relaxation time of the lazy random walk on $G$ and $d$ is the minimum degree in $G$. Alternatively, $m$ can be estimated in $O\left(t_{\mathrm{unif}} +t_{\ma

Constant Arboricity Spectral Sparsifiers. (arXiv:1808.05662v1 [cs.DS])

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

We show that every graph is spectrally similar to the union of a constant number of forests. Moreover, we show that Spielman-Srivastava sparsifiers are the union of O(logn) forests. This result can be used to estimate boundaries of small subsets of vertices in nearly optimal query time.

Cardinality Estimators do not Preserve Privacy. (arXiv:1808.05879v1 [cs.CR])

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

Cardinality estimators like HyperLogLog are sketching algorithms that estimate the number of distinct elements in a large multiset. Their use in privacy-sensitive contexts raises the question of whether they leak private information. In particular, can they provide any privacy guarantees while preserving their strong aggregation properties? We formulate an abstract notion of cardinality estimators, which captures this aggregation requirement: one can merge sketches without losing precision. We propose an

Lifted Wasserstein Matcher for Fast and Robust Topology Tracking. (arXiv:1808.05870v1 [eess.IV])

Monday, August 20, 01:30 UTC @ cs.CG updates on arXiv.org

This paper presents a robust and efficient method for tracking topological features in time-varying scalar data. Structures are tracked based on the optimal matching between persistence diagrams with respect to the Wasserstein metric. This fundamentally relies on solving the assignment problem, a special case of optimal transport, for all consecutive timesteps. Our approach relies on two main contributions. First, we revisit the seminal assignment algorithm by Kuhn and Munkres which we specifically adapt

Binary Search in Graphs Revisited. (arXiv:1702.08899v2 [cs.DS] UPDATED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

In the classical binary search in a path the aim is to detect an unknown target by asking as few queries as possible, where each query reveals the direction to the target. This binary search algorithm has been recently extended by [Emamjomeh-Zadeh et al., STOC, 2016] to the problem of detecting a target in an arbitrary graph. Similarly to the classical case in the path, the algorithm of Emamjomeh-Zadeh et al. maintains a candidates' set for the target, while each query asks an appropriately chosen vertex

How did the shape of your network change? (On detecting anomalies in static and dynamic networks via change of non-local curvatures). (arXiv:1808.05676v1 [cs.DS])

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

Notions of local and non-local curvatures of higher-dimensional geometric shapes and topological spaces play a fundamental role in physics and mathematics in characterizing anomalous behaviours of these higher dimensional entities. However, using curvature measures to detect anomalies in networks is not yet very common due to several reasons such as lack of preferred geometric interpretation of networks and lack of experimental evidences that may lead to specific desired curvature properties. To this end

A Linear Algebra Formulation for Boolean Satisfiability Testing. (arXiv:1701.02401v2 [cs.CC] UPDATED)

Monday, August 20, 01:30 UTC @ cs.CC updates on arXiv.org

In the article \The State of SAT", the authors asked whether a procedure dramatically different from DPLL can be found for handling unsatisfiable instances. This study proposes a new linear programming approach to address this issue efficiently. Our experiments showed that the new method works for many unsatisfiable instances. However, we must concede that this method should be incomplete; otherwise, it will imply P=co-NP.

A $\phi$-Competitive Algorithm for Scheduling Packets with Deadlines. (arXiv:1807.07177v2 [cs.DS] UPDATED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

In the online packet scheduling problem with deadlines (PacketScheduling, for short), the goal is to schedule transmissions of packets that arrive over time in a network switch and need to be sent across a link. Each packet $p$ has a deadline $d_p$, representing its urgency, and a non-negative weight $w_p$, that represents its priority. Only one packet can be transmitted in any time slot, so, if the system is overloaded, some packets will inevitably miss their deadlines and be dropped. In this scenario,

Parallel and I/O-efficient Randomisation of Massive Networks using Global Curveball Trades. (arXiv:1804.08487v2 [cs.DS] UPDATED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

Graph randomisation is a crucial task in the analysis and synthesis of networks. It is typically implemented as an edge switching process (ESMC) repeatedly swapping the nodes of random edge pairs while maintaining the degrees involved. Curveball is a novel approach that instead considers the whole neighbourhoods of randomly drawn node pairs. Its Markov chain converges to a uniform distribution, and experiments suggest that it requires less steps than the established ESMC. Since trades however are

Efficiently Learning Mixtures of Mallows Models. (arXiv:1808.05731v1 [cs.DS])

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

Mixtures of Mallows models are a popular generative model for ranking data coming from a heterogeneous population. They have a variety of applications including social choice, recommendation systems and natural language processing. Here we give the first polynomial time algorithm for provably learning the parameters of a mixture of Mallows models with any constant number of components. Prior to our work, only the two component case had been settled. Our analysis revolves around a determinantal identity o

LP Relaxation and Tree Packing for Minimum $k$-cuts. (arXiv:1808.05765v1 [cs.DS])

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

Karger used spanning tree packings to derive a near linear-time randomized algorithm for the global minimum cut problem as well as a bound on the number of approximate minimum cuts. This is a different approach from his well-known random contraction algorithm. Thorup developed a fast deterministic algorithm for the minimum $k$-cut problem via greedy recursive tree packings. In this paper we revisit properties of an LP relaxation for $k$-cut proposed by Naor and Rabani, and analyzed by Chekuri, Gu

Optimization over Degree Sequences. (arXiv:1706.03951v2 [math.OC] CROSS LISTED)

Monday, August 20, 01:30 UTC @ cs.DS updates on arXiv.org

We introduce and study the problem of optimizing arbitrary functions over degree sequences of hypergraphs and multihypergraphs. We show that over multihypergraphs the problem can be solved in polynomial time. For hypergraphs, we show that deciding if a given sequence is the degree sequence of a 3-hypergraph is NP-complete, thereby solving a 30 year long open problem. This implies that optimization over hypergraphs is hard already for simple concave functions. In contrast, we show that for graphs, if the

Schnorr groups

Apple Is Privately Encouraging Paid App Developers to Move to Subscriptions

Tuesday, August 14, 21:26 UTC @ Daring Fireball

Interesting story by Kif Leswing for Business Insider, regarding a private meeting Apple held with indie developers in New York last year: The new way Apple wanted to promote: Instead of users paying for apps once, they’d pay on a regular basis, putting money into developer coffers on a regular schedule. Apple would still get a 30% cut of the subscription’s cost, but if a customer continued to subscribe after a year, Apple’s cut would go down to 15%. At the me

New Samsung Galaxy Watches Are Still Much Larger Than Apple Watches

Monday, August 13, 22:35 UTC @ Daring Fireball

Samsung is sticking with round faces — you certainly can’t call these ripoffs of Apple Watch. But I think that’s a mistake for a digital watch. At 42 and 46mm, both sizes are much larger (and heavier) than Apple Watches. Because Apple measures its watches vertically, they sound closer in size than they actually are. A 42mm Apple Watch is 36mm wide, and a 38mm Apple Watch is just 33mm wide. Apple remains t

So the company will let you “pause” a setting called Location History. Google says that will prevent the company from remembering where you’ve been.

Tuesday, August 07, 00:21 UTC @ The Apache Software Foundation Blog

by Bertrand Delacretaz I became active in the ASF in 2001 via Gianugo Rabellino -- he was the one who started the discussions with Apache Fop about me donating the jfor XLS-FO to RTF converter that I had developed earlier. It was already too late to uninvent RTF which is a terrible format, but I digress. I am currently a member of the Board of Directors of the ASF and have been doing a lot of thinking (and presentations) about what makes the ASF tick in terms of collabor

Apple Removed Infowars From iTunes Podcast Directory, Then YouTube and Facebook Followed Suit

Getting All Cases Of An Enum

Monday, August 06, 15:42 UTC @ Use Your Loaf

I think my favourite addition to Swift 4.2 might be having the compiler automatically generate an allCases collection for enums. How Many Cases In My Enum? It is often useful to know how many cases an enum has or to be able to iterate over all possible cases. Before Swift 4.2 you either needed to use a meta-programming tool like Sourcery or manually maintain the collection:

One of my favorite activities, when I travel, is to listen to people as they pass and try to guess what language they’re speaking. I’d like to think that I’ve gotten pretty good at it over the years (though I rarely get to know if I guessed right). If I’m lucky, I’ll recognize a word or phrase as a cognate of a language I’m familiar with, and narrow things down from there. Otherwise, I try to build up a phonetic in

Nikhil Sonnad, writing for Quartz: Facebook didn’t intend for any of this to happen. It just wanted to connect people. But there is a thread running from Perkins’ death to religious violence in Myanmar and the company’s half-assed attempts at combating fake news. Facebook really is evil. Not on purpose. In the banal kind of way. Underlying all of Facebook’s screw-ups is a bumbling obliviousness to real humans. The company’s singular focus on “connecting people” ha

Apple Will Soon Remove iOS and Mac Apps From Affiliate Program

Thursday, August 02, 18:17 UTC @ Daring Fireball

Stephen Hackett on Apple’s decision to remove apps from their affiliate program: Another angle here to consider is money. Payments made to people linking to apps with affiliate links comes out of Apple’s share of revenue generated by app sales and in-app purchases. How much money it costs them is unknown, but the idea that the reasons behind this move could be financial in nature feels pretty gross. Apple is a for-profit company, and it may have a real bottom-line reason to cl

Migrating an Objective-C class to Swift: a piecemeal approach

I’m currently working on a fairly large iOS app with a long history. We try to write new code in Swift, but about 75–80 % of the code base is still Objective-C. We don’t rewrite existing code in Swift just for the sake of it, but only if a subsystem is due for a major overhaul anyway. The exception to the rule: when a particular subsystem reaches a tipping point — say, 60 % of it is written in Swift — it can make sense to transition the rest as well in order to minimize pains caused by mixi

In the spirit of the original Lisp DEFSYSTEM, it compiles and loads software (mostly but not exclusively Common Lisp code) in the same image as it's running. Indeed, old time Lisp machines and Li

Never

Monday, July 30, 07:00 UTC @ NSHipster

“Never” is a proposition that an event doesn’t occur at any time in the past or future. It’s logical impossibility with a time axis; nothingness stretching out in all directions, forever. …which is why it’s especially worrisome to encounter this comment in code:

Drawing planar graphs with prescribed face areas

Friday, July 27, 13:11 UTC @ Journal of Computational Geometry

We study drawings of planar graphs where every inner face has a prescribed area. A plane graph is 'area-universal' if for every area assignment on the inner faces, there exists a straight-line drawing realizing the assigned areas. The only non-area-universal graph known so far is the octahedron graph. We give a simple counting argument that allows to prove non-area-universality for a large class of triangulations, namely Eulerian triangulations. Adding some geometric arguments, the concept  allo

Circular law for random matrices

Suppose you create a large matrix M by filling its components with random values. If M has size n by n, then we require the probability distribution for each entry to have mean 0 and variance 1/n. Then the Girko-Ginibri circular law says that the eigenvalues of M are approximately uniformly distributed in the unit disk in the complex plane. […]

Our solution combines existing techniques from mesh encoding with a novel use of maximal Schnyder woods. Our approach extends to higher gen

Topological drawings are natural representations of graphs in the plane, where vertices are represented by points, and edges by curves connecting the points. 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.

The Mythos of Model Interpretability

Tuesday, July 17, 10:39 UTC @ ACM Queue - All Queue Content

Supervised machine-learning models boast remarkable predictive capabilities. But can you trust your model? Will it work in deployment? What else can it tell you about the world? Models should be not only good, but also interpretable, yet the task of interpretation appears underspecified. The academic literature has provided diverse and sometimes non-overlapping motivations for interpretability and has offered myriad techniques for rendering interpretable models. Despite this ambiguity, many authors proclaim

Have you ever seen a unit test pass in isolation, but fail when run in a suite? Or vice versa, pass in a suite, but fail when run in isolation? Besides the other improvements for test-centric workflows, Xcode 10 brings a rarity: a new XCTest feature for unit tests! Randomizing test order will help us […]

Swift Tip: Notifications

Tuesday, July 03, 00:00 UTC @ objc.io

In Episode 107 of our Swift Talk series on refactoring large view controllers, we move code from a view controller to a child view controller. The resulting child view controller deals with keyboard notifications. In this week’s tip, we’ll show how to factor out that code as well.

Eugene Zaikonnikov: A tiny Lisp bytecode interpreter in Z-80 assembly

Monday, July 02, 15:00 UTC @ Planet Lisp

It all started with a raid on a long abandoned hosting service. Seen a mention of it in the news, leading to a vague recollection of using it for something.

A Shift In Tech: Machine Learning and AI

Monday, July 02, 00:00 UTC @ The Syndicate

Machine learning, and its yet-to-be-realized more advanced form artificial intelligence (AI), promise to change our world in myriad ways. One example will be disseminating new medical information to physicians. We’ve all been in waiting rooms while doctors bounce from patient to patient doing their best to help everyone. Once the hands-on patient care is complete, they still need to take notes, do administrative tasks — and they also want to have a life. Oh, and they need to stay current on

How to think about intangible ROI for x.ai

A couple months ago, we overviewed how we calculate the tangible business ROI for our AI scheduling assistants. We still recommend ensuring any AI investment you make is grounded in providing empirical business value. However, that doesn’t mean all the rewards you’ll reap from such an investment are easily measured, or will occur in the… The post How to think about intangible ROI for x.ai appeared
