ISSN NO 0261-8362 2 EDITOR'S CORNER When I started the Cubic Circular last year, I. intended to have 12 pages per issue and I wondered how I would fill them. As it turns out, material continues to arrive faster than I can deal with it or publish it, and two other magazines have started. The first two Circulars were already 16 pages and I have about 40 pages of type-script in front of me. Because of this and because the Spring issue is a bit late, we have decided to make this a DOUBLE ISSUE for Spring and Summer, i.e. issues number 3 & 4. Depending on how the material fits and on the printer, this issue will be 32 or 36 pages. Hence this issue completes the first year of the Circular. The next issue will appear in the Autumn, probably in October or November. Because of the extra weight of larger issues, the need to employ technical assistance and the fact that circulation is still confined to a small circle of cubologists, we find the current subscription of £2.50 per year is not really covering our costs. Hence we must raise the subscription to £4.00 for the next year (or $8.00). This may be revised later but we will accept renewals now at this rate. Do it faster! SONGS Mister Rubik, by the Barron Knights, (C1-15) is now on their LP "Twisting the knights Away". An English school group did a song of their own on TV while trying to restore their cubes at the same time. They didn't finish. A Hungarian husband and wife, Bea Muszty and András Dobay, have made an English single called "Trick in the Middle" about Rubik's cube (Start Records SP5 70537) - "Try to harmonize the colours of your life Or the faces of the cube to be alike. You can twist, twiddle and fiddle, But the trick's in the middle of the cube." Don Taylor has sent a photocopy of the cover of the Australian song. It's called "The Cube" by Mike Brady and http://www.geocities.com/jaapsch/puzzles/cubic3.htm Page 2 of 33 Cubic Circular, Issue 3 & 4 07/08/2007 03:38 PM the Cubettes. It has been done as a video clip with dancers. Claude Shannon has composed "A Rubric on Rubik Cubics" to the tune of 'Ta! Ra! Ra! Boom De Ay!'. It has six verses of 8 lines with six 4 line choruses, and ten footnotes: It's a bit long to copy here, but perhaps I'll put it in a later Circular.

This was jointly sponsored by Politoys, Konsumex and Ideal. There were contestants from 19 countries. Minh Thai, the US champion, won with a time of 22.95 sec. The competition was efficiently organized by Brian Cartmell, the public relations firm for Ideal (UK), so it had the same basic structure as the UK contest. The cubes were selected by Rubik from a special production run and competitors were given a sample to practice with. Competitors described them as pretty good. All had a standardized colour pattern with white opposite yellow, red opposite orange and blue opposite green (David Sibley calls this the 'plus and minus yellow pattern' since opposite faces differ by yellow.) and with blue, orange, yellow clockwise at a corner (spelling BOY). Rubik worked with some mathematicians to develop several patterns of similar complexity. (The contestants remarked that all the patterns seemed of equal difficulty.) Four sets of cubes were put in four of these patterns by Rubik and sealed in separate briefcases which were kept in a bank overnight and brought to the competition by the supervising lawyer. One case was opened and placed by the competitor's entrance. Each contestant picked one at random as he came on stage. (The competitors remained offstage until their turn came so they could not watch the previous attempts.) Each contestant had three attempts and the best time was taken. The fourth cube was used as an extra cube in case a cube came apart. In this event, the contestant got one extra trial. This happened seven times. The Finnish contestant's cube broke twice, so he lost one trial. The contestant had fifteen seconds to examine the cube in his hand. It was then set down on a photoelectric base. The timing was then based on the time from picking up the cube to setting it down again in completed form. There was a jury consisting of Rubik, myself, Georgina Tamás (Commercial Director, Konsumex), Peter Peacock (Marketing Director, Ideal (UK)), Rainer Seitz (Product Manager of Arxon and founder of the Rubik's Cube Club). Basically the jury was to guarantee fairness in the event of unexpected phenomena. Indeed the power for the TV and the display timer gave out in the middle of one trial. Fortunately the timing computers are battery powered and a valid time was obtained. One contestant started to do the cube during the study time - he was given an extra try. Once the display timer wouldn't reset after the study time and there was some delay, so the contestant was allowed a new examination period. The order in the first round was determined by a drawing the previous night. On the following rounds, the slowest contestants went first. The logo of the contest was a cube with one corner replaced by a globe. The prizes were three examples of these which were plated in gold, silver and bronze, together with a number of elegant Hungarian handicrafts. http://www.geocities.com/jaapsch/puzzles/cubic3.htm Page 4 of 33 Cubic Circular, Issue 3 & 4 07/08/2007 03:38 PM 5 The Contestants I give a summary about each contestant: Country.

  • 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.

They are formal versions of the simple, intuitive idea of "do something to set up another task which does something useful, and undo the setup." Commutators can be used to generate algorithms that only modify specific portions of a cube, and are intuitively derivable. Many puzzle solutions are heavily or fully based on commutators. Commutator and Conjugate Notation [X, Y] is a commonly used notation to represent the sequence X Y X' Y'. [X: Y] is a well-accepted representation of the conjugate X Y X'. Since commutators and conjugates are often nested together, Lucas Garron has proposed the following system for compact notation: Brackets denote an entire algorithm, and within these, the comma delimits a commutator, and a colon or a semicolon a conjugate.

    Rubik's Cube - Wikipedia, the free encyclopedia 5/11/11 6:47 PM Rubik's Cube From Wikipedia, the free encyclopedia The Rubik's Cube is a 3-D mechanical puzzle invented in Rubik's Cube 1974[1] by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the "Magic Cube",[2] the puzzle was licensed by Rubik to be sold by Ideal Toy Corp. in 1980[3] and won the German Game of the Year special award for Best Puzzle that year. As of January 2009, 350 million cubes have sold worldwide[4][5] making it the world's top-selling puzzle game.[6][7] It is widely considered to be the world's best-selling toy.[8] In a classic Rubik's Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally white, red, blue, orange, green, and yellow).[9] A pivot mechanism enables each face to turn independently, thus mixing up the Other names Magic Cube colours. For the puzzle to be solved, each face must be a Type Puzzle solid colour. Similar puzzles have now been produced with various numbers of stickers, not all of them by Rubik.
