Here's a short video we put together that gives you a sense of the work that goes into the changes and improvements we make to Google almost every day. While an improvement to the algorithm may start with a creative idea, it always goes through a process of rigorous scientific testing. www.google.com

This video illustrates how several simple sorting algorithms operate, using people as the objects to be sorted. Produced by the Algorithmic Thinking class as part of Knight School 2009 at Menlo School. For people who know nothing about computer science but want to know what the heck is going on, here are brief descriptions of each sorting algorithm. Insertion Sort: Select each element in the list, and move it left until you hit somebody less than it. For example, when the element '2' is selected in the video, it moves left (shifting everybody right out of the way) until it encounters '1', when it is inserted back into the list. Selection Sort: Pass through the entire list, keeping track of the minimum element so far seen. When the pass is finished, select the global minimum and (in this simplified version of the algorithm) add it to a list of sorted elements. Repeat this, selecting the minimum element each time. Mergesort: Sorting a big list is too hard, so instead sort the first and last halves of the list, and then merge the sorted sublists. Of course, to sort each half-list we sort each quarter-list, and so forth. Eventually we get down to sorting a list with only two elements, which is easy! The merge can also be done very easily, by simply taking the smaller of the top elements of each sublist and repeating until the sublists are empty. In the video, the splitting of the original list into halves, quarters, etc. is not shown - for simplicity we start by immediately <b>...</b>

This particular audibilization is just one of many ways to generate sound from running sorting algorithms. Here on every comparison of two numbers (elements) I play (mixing) sin waves with frequencies modulated by values of these numbers. There are quite a few parameters that may drastically change resulting sound - I just chose parameteres that imo felt best. After making this video I found that someone already tried to audibilize sorting algorithms: www.pillowsopher.com - he mentions other older attempt: www.math.ucla.edu And someone in comments metions similar attempt on different aproches to Towers of Hanoi problem in 1982; there was also attempt on trying to hear minimax search in chess engine in 2009: www.krazydad.com . This is my first attempt on making algorithms audible. For some time I was wondering what would it sound like if cpu made different noises for different instructions. It all started while trying to play raw files (texts, images, programs...), then I heard few "raw" tracks on Alva Noto CD... and then I did one strange audio-visual simulation vimeo.com and then I tried to play out voltage potentials simulated by spiking neural network implementation - it worked out really cool so I wanted to try something with algorithms - thats how I got here. I know this work is not novel but I feel it isn't explored enough. I see future uses of similar techniques in monitoring and debuging, teaching and gaining insight of more complicated algorithms, science (as an <b>...</b>

Google Tech Talk February 11, 2010 ABSTRACT Presented by Dr. Andy Yoo, Lawrence Livermore National Laboratory. Graphs have gained a lot of attention in recent years and have been a focal point in many emerging disciplines such as web mining, computational biology, social network analysis, and national security, just to name a few. These so-called scale-free graphs in the real world have very complex structure and their sizes already have reached unprecedented scale. Furthermore, most of the popular graph algorithms are computationally very expensive, making scalable graph analysis even more challenging. To scale these graph algorithms, which have different run-time characteristics and resource requirements than traditional scientific and engineering applications, we may have to adopt vastly different computing techniques than the current state-of-art. In this talk, I will discuss some of the findings from our studies on the performance and scalability of graph algorithms on various computing environments at LLNL, hoping to shed some light on the challenges in scaling large graph algorithms. Andy Yoo is a computer scientist in the Center for Applied Scientific Computing (CASC). His current research interests are scalable graph algorithms, high performance computing, large-scale data management, and performance evaluation. He has worked on the large graph problems since 2004. In 2005, he developed a scalable graph search algorithm and demonstrated it by searching a graph <b>...</b>

Google Tech Talks March, 14 2008 ABSTRACT Many problems in Natural Language Processing (NLP) involves an efficient search for the best derivation over (exponentially) many candidates, especially in parsing and machine translation. In these cases, the concept of "packed forest" provides a compact representation of the huge search spaces, where efficient inference algorithms based on Dynamic Programming (DP) are possible. In this talk we address two important open problems within this framework: exact k-best inference which is often used in NLP pipelines such as parse reranking and MT rescoring, and approximate inference when the search space is too big for exact search. We first present a series of fast and exact k-best algorithms on forests, which are orders of magnitudes faster than previously used methods on state-of-the-art parsers such as Collins (1999). We then extend these algorithms for approximate search when the forests are too big for exact inference. We discuss two particular instances of this new method, forest rescoring for MT decoding with integrated language models, and forest reranking for discriminative parsing. In the former, our methods perform orders of magnitudes faster than conventional beam search on both state-of-the-art phrase-based and syntax-based systems, with the same level of search error or translation quality. In the latter, faster search also leads to better learning, where our approximate decoding makes whole-Treebank discriminative <b>...</b>

The algorithm works reasonably similar to Search Engine Optimization. Klurig Analytics, specialists in Social Media ROI, created this video to show how the algorithm works and why it is necessary for a social media marketer to understand the Facebook Edgerank Algorithm in order to write posts that are displayed on users' Top News feed.

www.molemanfilm.com Please rate the film on IMDb www.imdb.com In the 1980's, something changed the world forever. Computer technology, mostly due to the appearance of affordable Commodore 64's, entered households worldwide, providing the opportunity for everyone to create digital art. But existing art forms weren't the only ones to be re-implemented on these computers; brand new forms of art also appeared, ones thought to be impossible up to that point. Computers provided an opportunity for the creator to produce visuals and sound effects and combine them to create the ultimate audiovisual experience, by using only the language of mathematics and writing program code, without physical interaction. As a result of such techniques, demos were born, and with them, the demoscene subculture. A demo can best be understood as a spectacular animated music video which is usually a few minutes long. And yet it's something entirely different from a traditional video. Computer technics is the fastest developing part of our world, which produces more and more new opportunities for art. Moleman shows you now a digital subculture, where artists don't use always the latest technology, but their aim is also to bring out the best from 30 year-old computer technics.
