Speed-post network Ghost Cube After months of work, we are proud to bring you a remarkable puzzle, the Ghost Cube from puzzle designer Adam G Cowan! The ghost cube is an exercise in making a 3x3x3 shape modification that is as challenging as possible while only allowing one solution. Misaligned layers, odd shaped pieces, and only one color all add to the challenge. "When I designed this puzzle back in 2008, I was inspired by Tony Fisher's Golden Cube, itself an iconic puzzle. The Ghost Cube design gradually formed over several days of 'tweaking' a basic concept until I had something really interesting. The very first prototype was printed by Geert Hellings and shown at DCD 2008 with good reviews, and early in 2009, several were made for sale by Jason Smith. After the initial sales, the Ghost Cube concept sat on the back shelf for a while, and to my surprise, several puzzle builders created their own hand made versions (including a 7x7x7 version!). Suddenly there was a strong desire to produce this puzzle, and I set to work on an injection molded production design." "I am very happy with the results, and glad that I will be able to share this puzzle with the entire puzzle community!" Enjoy! Adam G Cowan.

  • Benchmarking Beginner Algorithms for Rubik's Cube
    DEGREE PROJECT, IN COMPUTER SCIENCE , FIRST LEVEL STOCKHOLM, SWEDEN 2015 Benchmarking Beginner Algorithms for Rubik's cube ANDREAS NILSSON, ANTON SPÅNG KTH ROYAL INSTITUTE OF TECHNOLOGY CSC SCHOOL Supervisor: Michael Schliephake Examiner: Örjan Ekeberg Abstract Over the years different algorithms have been developed to step-by-step solve parts of the Rubik’s cube until fi- nally reaching the unique solution. This thesis explores two commonly known beginner algorithms for solving Rubik’s cube to find how they differ in solving speed and amount of moves. The algorithms were implemented and run on a large amount of scrambled cubes to collect data. The re- sults showed that Layer-by-layer with daisy algorithm had a lower average amount of moves than the Dedmore al- gorithm. The main difference in amount of moves lies in the steps that solve the last layer of the cube. The Layer- by-layer with daisy algorithm uses only one-seventh of the time-consuming operations that Dedmore algorithm uses, which concludes that it is more suitable for speedcubing. Sammanfattning Över åren har ett antal olika algoritmer utvecklats för att steg-för-steg lösa delar av Rubik’s kub för att till sist kom- ma fram till den unika lösningen. Denna rapport utforskar två allmänt kända nybörjaralgoritmer för att lösa Rubik’s kub, för att finna hur dem skiljer sig åt i tid samt antal operationer för att nå lösningen. Algoritmerna implemen- terades och kördes på ett stort antal blandade kuber för att samla data. Resultatet visar att Lager-för-lager med daisy algoritmen hade ett lägre genomsnittligt antal förflyttning- ar jämfört med Dedmore algoritmen.

    Mathematics of the Rubik's cube Associate Professor W. D. Joyner Spring Semester, 1996{7 2 \By and large it is uniformly true that in mathematics that there is a time lapse between a mathematical discovery and the moment it becomes useful; and that this lapse can be anything from 30 to 100 years, in some cases even more; and that the whole system seems to function without any direction, without any reference to usefulness, and without any desire to do things which are useful." John von Neumann COLLECTED WORKS, VI, p. 489 For more mathematical quotes, see the first page of each chapter below, [M], [S] or the www page at http://math.furman.edu/~mwoodard/mquot. html 3 \There are some things which cannot be learned quickly, and time, which is all we have, must be paid heavily for their acquiring.

Analysis and comparison between various algorithms; considering speed and optimality in decreasing the amount of steps it takes to complete a cube. A prototype program will be presented as a tool to help put the thesis into practice using selected algorithms. However creating this kind of application can be quite complex taking into consideration the sheer size of algorithms and different patterns, searching methods and the complexity of the programming language itself. Developing this kind of program requires handling many different parts of code and algorithms simultaneously.

  • NEWSLETTER July 2021
    NEWSLETTER July 2021 Welcome to our July Newsletter- In last summer's TURN TO PAGE 14 newsletter introduction, I referred to 2019-20 being a year 'unlike any other'. Sadly, it would seem that 2020-21 has also been a year 'unlike TO FIND OUT THE WINNER OF any other' and I don't think any of us could have imagined the pandemic continuing for as long as it has or having the very significant impact on the world of education in the way that it has. There are, however, brighter times ahead and we look forward to a return to school in September that feels more like our normality. We have been carefully reviewing our procedures in school and we recognise that some of the practices that we have brought in due to COVID-19 have actually enhanced what we do and helped us to raise standards. Certain other things, we will not be continuing with- we SAVE THE DATE! are very much looking forward to our teachers being able to base YEAR 6 OPEN EVENING themselves in their own rooms again, allowing the students to move more freely around school from subject area to subject area. Thursday 23rd September We can’t wait to welcome Year 6 students As ever, we have not compromised on all the fantastic extra activities and their parents/carers to our Open and opportunities on offer to our students and this July newsletter Evening. Students will have the contains so many amazing stories and articles about our students' opportunity to visit each of our subject achievements.

  • Paris Rubik's Cube World Championship to Be Biggest Ever
    Paris Rubik’s Cube World Championship to be Biggest Ever Submitted by: Rubik’s Cube Wednesday, 14 June 2017 The Rubik’s Cube World Championship (http://www.rubiksworldparis2017.com/en/home/), which sees competitors battle to solve the iconic cube (https://www.rubiks.com/) as quickly as possible, is being staged in France for the first time from Thursday 13 to Sunday 16 July 2017 and will see a record number of ‘speedcubers’ in action. Australian Feliks Zemdegs will defend the world title for the Rubik’s Cube, which he has held since winning in 2013 with an average solve time of 8.18 seconds and defended in 2015 with an average solve time of 7.56 seconds. Although the championship is traditionally aimed at individual competitors, this year the inaugural Nations Cup will see teams of three from 45 countries go head-to-head for the first time. Due to the excitement around the new Nations Cup format, it is anticipated that Ern Rubik, the legendary Hungarian creator of the iconic Rubik’s Cube, will be in attendance at the event. A professor of architecture from Budapest, he created the cube in 1974 to encourage his students to think about spatial relationships. Since its international launch in 1980, an estimated 450 million Rubik’s Cubes have been sold, making it the world’s most popular toy. The Rubik’s Cube World Championship will take place at Les Docks de Paris, France, and will welcome 1,100 competitors from 69 countries, competing in eighteen individual competition classes, including blindfolded solving, solving with feet and tackling different puzzles.

Dowiesz się w niej wiele rzeczy na jej temat. Jednak znajomość teorii to nie wszystko. Chodzi przede wszystkim o praktykę. Nie mówię, że teoria to nic ważnego. Absolutnie nie! Od czegoś trzeba przecież zacząć, jednak co da Ci znajomość teorii, jeśli nie umiesz jej wykorzystać. Książka składa się więc z dwóch części: teoretycznej i praktycznej. W każdej możesz dowiedzieć się czegoś fascynującego, więc czytaj do końca, aby dowiedzieć się wszystko o kostce Rubika. Chcę w tym tekście pokazać również związek matematyki z tą łamigłówką. Szczególnie geometrią. Sam wynalazca, Ernő Rubik stworzył kostkę Rubika, aby rozwinąć u swoich studentów myślenie o geometrii trójwymiarowej, co doskonale mu się udało. 3 1. Co to jest kostka Rubika? Co to jest kostka Rubika? Domyślnie kostka Rubika to sześcian średniej wielkości, który składa się z 27 mniejszych sześcianów (zmniejszonych w skali 1:3- jeden mały sześcian jest trzykrotnie mniejszy od całej kostki) .

  • Mike Mesenbrink Nicole Stevenson Math 305 Final Project May 9, 2012
    Mike Mesenbrink Nicole Stevenson Math 305 Final Project May 9, 2012 Introduction When most people hear about the Rubik’s Cube, they think about the 3 x 3 x 3 game cube that was invented in 1972 by Hungarian architect, designer, and university professor named Ernő Rubik. What many people do not know is the man who is credited with inventing the cube was not the first person to come up with the idea. In March 1970, two years before the patented Rubik’s cube came about, a Canadian man by the name of Larry Nichols invented a 2 x 2 x 2 “Puzzle with Pieces Rotatable in Groups,” which would soon become the Pocket Cube. The fist cube was held together with magnets, and did not become all the rage until a few years later. Eventually Ernő Rubik beat Nichols in the race to get the 2 x 2 x 2 cube patented on March 29, 1983.

It goes under various names, such as Mini Cube and Pocket Cube. The puzzle is built from 8 smaller cubes, i.e. a 2×2×2 cube. Each face can rotate, which rearranges the 4 small cubes at that face. The six sides of the puzzle are coloured, so every small cube shows three colours. This puzzle is equivalent to just the corners of the normal Rubik's cube.
