Generations from now - maybe millennia from now - when archaeologists look back on our time, they may find evidence of the moment when we went from playing physical sports to e-sports. Videogame athletes are watched by millions of fans as they compete for millions of dollars in prize money. Promoters now want to move e-sports from living rooms into sports arenas. Jeff Landa follows one game company to learn how it's done. JEFF LANDA, BYLINE: The Key Arena in Seattle, Wash., is sold out.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

The way children play iPad games could reveal if they have autism, researchers have found. They found those with the condition used greater force and moved their finger in different ways. It is hoped the app could lead to earlier diagnosis and treatment. The children were asked to play games on smart tablet computers with touch-sensitive screens and embedded movement sensors. Researchers at the University of Strathclyde and colleagues at the start-up Harimata added code to two commercially available games for children in order for them to capture sensor and touch-screen data as they children played.

Scientists and engineers around the world are quietly working on the next generation of machines which could usher in a new age of computing. Even the fastest supercomputers today are still bound by the system of 1's and 0's which enabled the very first machines to make calculations. But experts believe that drawing on the strange properties of the quantum world can enable computers to break free from these binary shackles, creating the most powerful problem-solving machines on the planet. Now, according to New Scientist, researchers at Google may announce a breakthrough as soon as next year, potentially reaching what the company terms'quantum supremacy' before anyone expected. Despite the great promise, one of the major stumbling blocks for the development of quantum computers has been demonstrating they can beat classical computers – achieving what computer scientists call quantum supremacy.

You may have heard of the '10,000-hour rule'; the belief that it takes thousands of hours of intense practice to become an expert in something. But is that really all it takes to achieve greatness? Recent research suggests that other factors such as genetics influence the likelihood that you will try, enjoy and excel at a performance activity. Writing in The Conversation, Kathryn Friedlander and Philip Fine, psychology researchers at the University of Buckingham explain how they tested the theory in the highly challenging arena of cryptic crossword solving. They believe, at least in solving crosswords, the ability to think flexibly is more important than hours of practice.

Earlier this week, Google announced that its popular Waze app, which offers crowd-sourced navigation and has 65 million active users, plans to explore a carpooling feature in the Bay Area sometime this fall. Drummond's departure ends a three-year stint with the company that began in 2013, when Google invested 360 million in Uber. Both companies released statements attesting to their continued collaborative spirit. "I wish David and Alphabet the best, and look forward to continued cooperation and partnership," Uber CEO Travis Kalanick said. Drummond said that Google Ventures "remains an enthusiastic investor and Google will continue to partner with Uber."

In this paper, we investigate the possibility of improvement of the widely-used filtering algorithm for the linear constraints in constraint satisfaction problems in the presence of the alldifferent constraints. In many cases, the fact that the variables in a linear constraint are also constrained by some alldifferent constraints may help us to calculate stronger bounds of the variables, leading to a stronger constraint propagation. We propose an improved filtering algorithm that targets such cases. We provide a detailed description of the proposed algorithm and prove its correctness. We evaluate the approach on five different problems that involve combinations of the linear and the alldifferent constraints. We also compare our algorithm to other relevant approaches. The experimental results show a great potential of the proposed improvement.

SEBOOST applies a secondary optimization process in the subspace spanned by the last steps and descent directions. The method was inspired by the SESOP optimization method for large-scale problems, and has been adapted for the stochastic learning framework. It can be applied on top of any existing optimization method with no need to tweak the internal algorithm. We show that the method is able to boost the performance of different algorithms, and make them more robust to changes in their hyper-parameters. As the boosting steps of SEBOOST are applied between large sets of descent steps, the additional subspace optimization hardly increases the overall computational burden. We introduce two hyper-parameters that control the balance between the baseline method and the secondary optimization process. The method was evaluated on several deep learning tasks, demonstrating promising results.
