The game of Go has long been viewed as the most challenging of classic games for artificial intelligence owing to its enormous search space and the difficulty of evaluating board positions and moves. Here we introduce a new approach to computer Go that uses ‘value networks’ to evaluate board positions and ‘policy networks’ to select moves. These deep neural networks are trained by a novel combination of supervised learning from human expert games, and reinforcement learning from games of self-play. Without any lookahead search, the neural networks play Go at the level of stateof-the-art Monte Carlo tree search programs that simulate thousands of random games of self-play. We also introduce a new search algorithm that combines Monte Carlo simulation with value and policy networks. Using this search algorithm,our program AlphaGo achieved a 99.8% winning rate against other Go programs, and defeated the human European Go champion by 5 games to 0. This is the first time that a computer program has defeated a human professional player in the full-sized game of Go, a feat previously thought to be at least a decade away.

Using Google’s new Public Data Explorer tool, Ola Rosling demonstrates the effectiveness of visualizing datasets. Looking toward the next political election, Rosling hopes voters will use the tool to answer questions like: How was the money spent? Where are the biggest problems?

Ola Rosling of Google Public Data gives a presentation titled, “Google Public Data Explorer” at the Berkeley Graduate School of Journalism. This program was recorded on April 18, 2010.

Ola Rosling co-founded the Gapminder Foundation and led the development of Trendalyzer, a software that converts time series statistics into animated, interactive and comprehensible graphics. The aim of his work is to promote a fact-based world view through increased use and understanding of freely accessible public data.

In March 2007, Google acquired the Trendalyzer software, where Rosling and his team are now scaling up their tools and making them freely available for any individual or organization to use for analyzing and visualizing data.

4D Rubik’s cube

Published on Jun 17, 2016

This video is an introduction to the mysterious 4D Rubik’s cube. Here my main focus is on revealing some ingenious tricks that will allow you to design your own algorithms for this crazy puzzle based on what you already know about the normal Rubik’s cube.

Part 2 of this video is a hands-on introduction to the 4D Rubik’s cube simulator “Magic Cube 4D”. It is hosted on Mathologer 2:

You can download “Magic Cube 4D” for free from here: http://superliminal.com/cube/cube.htm
If you are really daring/totally insane and would like to try blindsolving the 4D Rubik’s cube or any of the other puzzles included in “Magic Cube 4D”, there is a custom made Mathologer version of the program that you can download from here: http://superliminal.com/cube/mc4d-bli…
(ctrl-d will toggle between greyed out and normal coloured pieces).

Special thanks go to Melinda Green, one of the developers of Magic Cube 4D and the person behind the Magic Cube 4D website for introducing me to the world of higher-dimensional twisty puzzles, answering my many questions about the program and putting together the custom made blindcubing version of the program.

I’ve used the following fabulous programs to generate the clips of 3D and 4D Rubik’s cubes doing their thing featured in this video:

1. CubeTwister by Werner Randelshoferhttps://www.randelshofer.ch/cubetwister/

2. Magic Cube 3D by David Vanderschel http://david-v.home.texas.net/MC3D/

3. Magic Cube 5D by Roice Nelson http://www.gravitation3d.com/magiccub…

4. Magic Puzzle Ultimate by Andrey Astrelin http://cardiizastrograda.com/astr/MPUlt/ and, of course,

5. Magic Cube 4D itself.

Enjoy!

Some footnotes (for experts):
1. In a scrambled normal Rubik’s Cube the permutations of edges and corners will always have the same parity, that is, either both will be odd or both even. The four algorithms that I start with (cycling 3 edges, cycling 3 corners, flipping 2 edges, twisting 2 corners) correspond to even permutations of both the edges and the corners. This means that you won’t be able to solve the normal Rubik’s cube by just using these algorithms if the parity of the edge (and corner) permutation is odd. However, on closer inspection it turns out that you can do so if that parity is even. And, if it is odd, just executing one quarter turn will turn these odd permutations into even permutations which can then be unscrambled just using those for algorithms.
2. The face piece and edge piece permutations of the 4D Rubik’s cube are connected in a similar way, that is, either both permutations are odd or both are even. This means that if you get stuck solving the face hypercubies just using the algorithms that I talk about in the video (which all correspond to even permutations of those pieces), just execute a suitable twist and you are on your way. Once the face hypercubies are solved just using our algorithms you can solve the edge hypercubies. The corner piece permutation is always even and can always be solved just using the algorithms derived in the video.

Agile management

Agile management, or agile process management, or simply agile refer to an iterative, incremental method of managing the design and build activities for engineering, information technology, and other business areas that aims to provide new product or service development in a highly flexible and interactive manner; an example is its application in Scrum, an original form of agile software development.[1] It requires capable individuals from the relevant business, openness to consistent customer input, and management openness to non-hierarchical forms of leadership. Agile can in fact be viewed as a broadening and generalization of the principles of the earlier successful array of Scrum concepts and techniques to more diverse business activities. Agile also traces its evolution to a “consensus event”, the publication of the “Agile manifesto“, and it has conceptual links to lean techniques, kanban (かんばん(看板)?), and the Six Sigma area of business ideas.[1]

Agile X techniques may also be called extreme process management. It is a variant of iterative life cycle[2] where deliverables are submitted in stages. The main difference between agile and iterative development is that agile methods complete small portions of the deliverables in each delivery cycle (iteration)[3] while iterative methods evolve the entire set of deliverables over time, completing them near the end of the project. Both iterative and agile methods were developed as a reaction to various obstacles that developed in more sequential forms of project organization. For example, as technology projects grow in complexity, end users tend to have difficulty defining the long term requirements without being able to view progressive prototypes. Projects that develop in iterations can constantly gather feedback to help refine those requirements. According to Jean-Loup Richet (Research Fellow at ESSEC Institute for Strategic Innovation & Services) “this approach can be leveraged effectively for non-software products and for project management in general, especially in areas of innovation and uncertainty. The end result is a product or project that best meets current customer needs and is delivered with minimal costs, waste, and time, enabling companies to achieve bottom line gains earlier than via traditional approaches.[4] Agile management also offers a simple framework promoting communication and reflection on past work amongst team members.[5]

Agile methods are mentioned in the Guide to the Project Management Body of Knowledge (PMBOK Guide) under the Project Lifecycle definition:

Adaptive project life cycle, a project life cycle, also known as change-driven or agile methods, that is intended to facilitate change and require a high degree of ongoing stakeholder involvement. Adaptive life cycles are also iterative and incremental, but differ in that iterations are very rapid (usually 2-4 weeks in length) and are fixed in time and resources.[6]

The Personal Software Process (PSP)

The Personal Software Process (PSP) is a structured software development process that is intended to help software engineers better understand and improve their performance by tracking their predicted and actual development of code. The PSP was created by Watts Humphrey to apply the underlying principles of the Software Engineering Institute’s (SEI) Capability Maturity Model (CMM) to the software development practices of a single developer. It claims to give software engineers the process skills necessary to work on a Team Software Process (TSP) team.

“Personal Software Process” and “PSP” are registered service marks of the Carnegie Mellon University.[1]
