Chilimbi , Mark D. Larus , ” Hardware trends have produced an increasing disparity between processor speeds and memory access times. While a variety of techniques for tolerating or reducing memory latency have been proposed, these are rarely successful for pointer-manipulating programs. This paper explores a complementary appro This paper explores a complementary approach that attacks the source poor reference locality of the problem rather than its manifestation memory latency. It demonstrates that careful data organization and layout provides an essential mechanism to improve the cache locality of pointer-manipulating programs and consequently, their performance. To reduce the cost of applying these techniques, this paper discusses two strategies-cache-conscious reorganization and cacheconscious allocation–and describes two semi-automatic toolsccmorph and ccmalloc-that use these strategies to produce cache-conscious pointer structure layouts. Our evaluations, with microbenchmarks, several small benchmarks, and a couple of large real-world applications, demonstrate that the cache-conscious structure layouts produced by ccmorph and ccmalloc offer large performance benefit-n most cases, significantly outperforming state-of-the-art prefetching.

Code-Dependent: Pros and Cons of the Algorithm Age

Randy Olson Posted in analysis , data visualization , machine learning As I found myself unexpectedly snowed in this weekend, I decided to take on a weekend project for fun. I was going to pull out every machine learning trick in my tool box to compute the optimal search strategy for finding Waldo. The books consist of a series of detailed double-page spread illustrations depicting dozens or more people doing a variety of amusing things at a given location.

But most of the algorithm have the same problem, which is that with the increase of users, algorithm optimization process is becoming slow, and easy to fall into local optimal solution. This paper proposes an algorithm based on graph, which we name it SimRank-ant colony optimization (SR-ACO).

The author is a very clever woman who didn’t disguise this from her dating profiles or the book reader, and thereby lacked success on dating sites and alienated those people here who think that women should be sweet, dumb themselves down, and be as entirely conventional as possible. They should also show skin. Kim Kardashian is famous for her face, body and fantastic publicity. The fact that none of these came about naturally and cost plenty of money is irrelevant.

Th This is a really good book. The closer you can get to projecting that image, but preferably blonde, a bit less arse, and trying to project that you have a great sense of humour, are always up for fun and definitely like sports and everything men do, the more popular you will be.


When this simple reflex network is recreated on a computer, the simulated worm reacts in exactly the same way to a virtual stimulation because that behavior is hard-wired in its neural network. A component on a turntable is mapped by the scanner, which is mounted to a robot arm while algorithms create a 3D image in the background. A simulation of the image checks whether a 3D print would meet the relevant stability requirements, and then the component is printed.

During an initial scan, algorithms calculate what further scans are required so the object can be recorded with the fewest number of scans; this enables the system to rapidly and independently measure objects that are unknown to it. The project involved 25 epilepsy patients with electrodes implanted in their brain, which were used to record high-resolution brain activity during memory tasks.

Thankfully, what we’ve described so far is the “uncompressed” image format. What could we do to reduce the image file size? One simple strategy is to reduce the “bit-depth” of the image from 8 bits per channel to a smaller color palette: What if we reduced the palette to colors? Left to right PNG: Complex scenes with gradual color transitions gradients, sky, etc. On the other hand, if the image only uses a few colors, then a large palette is simply wasting precious bits! Next, once we’ve optimized the data stored in individual pixels we could get more clever and look at nearby pixels as well:

Abstract Background Accurate assignment of gestational age at time of fetal death is important for research and clinical practice. An algorithm to estimate gestational age GA at fetal death was developed and evaluated. The SCRN conducted a population-based case-control study of women with stillbirths and live births from to in five geographic catchment areas. Rules were developed to estimate a due date, identify an interval during which death likely occurred, and estimate GA at the time of fetal death.

Reliability of using fetal foot length to estimate GA at death was assessed.

The game of googol[ edit ] According to Ferguson , the secretary problem appeared for the first time in print in Martin Gardner ‘s column of Scientific American in Here is how Martin Gardner formulated the problem: The numbers may range from small fractions of 1 to a number the size of a googol 1 followed by a hundred 0s or even larger.

These slips are turned face down and shuffled over the top of a table. One at a time you turn the slips face up. The aim is to stop turning when you come to the number that you guess to be the largest of the series.

Soon thereafter, the internet exploded on the scene and online dating was off to the races. A far cry from when fathers would make deals to arrange with other fathers whom their daughter would marry — or a matchmaker in the community would negotiate the transaction, current singles eagerly take matters into their own hands. Over 2, internet dating sites have created a process that emphasizes three things: When Tinder hit the scene in , it seemed a suitor could arrive as fast as your thumb could swipe.

Perhaps too many choices creates a scenario where none of them look all that appealing. Consider the idea that overload is simply exhausting and narrowing the numbers maintains enthusiasm for the process.

Tinder released an updated version of its matching algorithm today, a “big change” that CEO Sean Rad has been hyping for the past week. In a blog post, Tinder offered few details on the new.

A new book offers mathematical puzzles, such as fitting a coin through a hole that seems too small to accommodate it By Colm Mulcahy July 31, Things to Make and Do in the Fourth Dimension: Farrar, Straus and Giroux, ; pages. Parker also enlivens his chapters with numerous surprises. The display resolution on a domino computer display is terrible Manchester, Chapter Two opens with the problem of slicing into equal-size pieces an idealized circular pizza which is infinitely thin—but some of the pieces must not touch the center.

He encourages readers to use a compass to experiment and offers several simple solutions to the problem. Curiously there is no mention of what is surely the most common occurrence of this in real life: He shows that if the Greek rules of geometry are modified a little, as they are in origami, formerly impossible things like trisecting any angle suddenly become doable.

Much like you don’t need to buy the cow if you can enjoy its milk for free, it might seem a little weird to pay for online dating. After all, there are so many free dating apps and services , so why should you subscribe to an expensive monthly service that can’t guarantee success? Ask the experts, and they’ll be the first to tell you that if you truly want to fall madly, deeply, truly in love, put your money where you want your heart to be.

The person you choose changes everything. It can make or break lifelong happiness, the opportunity to build a family, and, well, tax savings. Also, paying for dating might actually save you money and time, in the long run, which, as you know, means more than gold.

References Alternating and Augmenting Paths Graph matching algorithms often use specific properties in order to identify sub-optimal areas in a matching, where improvements can be made to reach a desired goal. Two famous properties are called augmenting paths and alternating paths, which are used to quickly determine whether a graph contains a maximum, or minimum, matching , or the matching can be further improved.

The goal of a matching algorithm, in this and all bipartite graph cases, is to maximize the number of connections between vertices in subset , above, to the vertices in subset , below. Unmatched bipartite graph Most algorithms begin by randomly creating a matching within a graph, and further refining the matching in order to attain the desired objective.

Random initial matching , , of Graph 1 represented by the red edges , with the matching, , is said to have an alternating path if there is a path whose edges are in the matching , , and not in the matching, in an alternating fashion. An alternating path usually starts with an unmatched vertex and terminates once it cannot append another edge to the tail of the path while maintaining the alternating sequence.

An alternating path in Graph 1 is represented by red edges, in , joined with green edges, not in. An augmenting path, then, builds up on the definition of an alternating path to describe a path whose endpoints, the vertices at the start and the end of the path, are free, or unmatched, vertices; vertices not included in the matching. Finding augmenting paths in a graph signals the lack of a maximum matching. The matching, , for , does not start and end on free vertices, so it does not have an augmenting path.

Computing the optimal road trip across the U.S.

Several compression algorithms compress some kinds of files smaller than the Huffman algorithm , therefore Huffman isn’t optimal. These algorithms exploit one or another of the caveats in the Huffman optimality proof. Whenever we have a we code each symbol independently in an integer number of bits, and b each symbol is “unrelated” to the other symbols we transmit no mutual information, statistically independent, etc.

By relaxing the binary Huffman restriction that each input symbol must be encoded as an integer number of bits, several compression algorithms, such as range coding, are never worse than, and usually better than, standard Huffman. One can do better than plain Huffman by “decorrelating” the symbols, and then using the Huffman algorithm on these decorrelated symbols.

CLOCK is a classical cache replacement policy dating back to that was proposed as a low-complexity approximation to LRU. On every cache hit, the policy LRU needs to move the accessed item to the most recently used position, at which point, to ensure consistency and correctness, it serializes cache hits behind a single global lock.

Innovation, the Internet, gadgets, and more. Out now from Farrar, Straus and Giroux. Finding a life partner is a delicate balance. This makes permanently partnering up with the first person you date a bit of a gamble: You should date a few people to get the lay of the land. That said, if you take too long dating people, you run the risk of missing your ideal partner and being forced to make do with whoever is available at the end. The ideal thing to do would be to date just the right number of people to gain the best sense of your options while leaving the highest probability of not missing your ideal partner.

Luckily, math has made it easy for us: That right number of people is the square root of the total number of people you could date in your life. How you estimate the size of your possible dating population is entirely up to your statistical skills and the level of your self-confidence, as is how you then collect your sample.
