Gilles Roux
Gilles Roux (born 20 January 1971) is a French speedcuber primarily known for inventing a 3x3x3 Rubik's Cube method, the Roux Method, and achieving fast times with it. WCA Gilles was a member of the World Cube Association Board from October 2004 until 1 November 2008. During his time as a board member, Gilles helped organize many competitions as a WCA delegate. He also contributed to WCA by creating much needed regulations which would in turn help out cubers all over the world. Presently, Gilles is a technical advisor for the WCA and assists when needed. Roux method Over a span of years, Gilles developed his own method to solve the 3x3x3 cube. Using a smaller quantity of memorized algorithms than most methods of solving, Roux still found his method to be fast and efficient. The first step of the Roux method is to form a 3×2×1 block. The 3×2×1 block is usually placed in the lower portion of the left layer. The second step is to create another 3×2×1 on the opposite side. ...

Speedcubing
Speedcubing (also known as speedsolving, or cubing) is a competitive sport involving solving a variety of combination puzzles, the most famous being the 3x3x3 puzzle or Rubik's Cube, as quickly as possible. An individual who practices solving twisty puzzles is known as a speedcuber (when solved specifically focusing on speed), or a cuber. For most puzzles, solving involves performing a series of moves or sequences that alters a scrambled puzzle into a solved state, in which every face of the puzzle is a single, solid color. Competitive speedcubing is mainly regulated by the World Cube Association (WCA). The WCA currently recognizes 17 speedcubing events: the cubic puzzles from the 2x2–7x7, the Pyraminx, Megaminx, Skewb, Square-1, and Rubik's Clock, as well as the 3x3, 4x4, and 5x5 Blindfolded, 3x3 One-handed, 3x3 Fewest Moves, and 3x3 Multi-blind. , the 3x3x3 world record single is 3.47 seconds held by Yusheng Du. The 3x3x3 world record average is 4.86 seconds, tied by ...

Rubik's Cube
The Rubik's Cube is a 3-D combination puzzle originally invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, and then by Ideal Toy Corp in 1980 via businessman Tibor Laczi and Seven Towns founder Tom Kremer. The cube was released internationally in 1980 and became one of the most recognized icons in popular culture. It won the 1980 German Game of the Year special award for Best Puzzle. , 350 million cubes had been sold worldwide, making it the world's bestselling puzzle game and bestselling toy. The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014. On the original classic Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. Some later versions of the cube have been updated to use coloured plastic panels instead, ...

World Cube Association
The World Cube Association (WCA) is the worldwide non-profit organization that regulates and holds competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as '' twisty puzzles'' (a subcategory of combination puzzles). The most famous of those puzzles is the Rubik's Cube. The WCA was founded by Ron van Bruchem of the Netherlands and Tyson Mao of the United States in 2004. The goal of the World Cube Association is to have "more competitions in more countries with more people and more fun, under fair conditions." In 2017, they started work to become a non-profit organization and on November 20, 2017, the state of California accepted the initial registration of the World Cube Association. The organization is run by the board members. It assigns different teams and committees as well as delegates who can organize official competitions. The presence of a delegate is required to make the competition official. , more than 165,000 people from ar ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of spac ...

Competition
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including recognition: Competition occurs in nature, between living organisms which co-exist in the same environment. Animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economies and business, often associated with business competition as companies are in competition with at least one other firm over the same group of customers. Competition inside a compan ...

Lars Petrus
Lars Erik Petrus (born 4 November 1960 in Luleå in Sweden) is an accomplished speedcuber. In 1982, he became the national champion of Sweden, and went on to finish fourth overall at the first official Rubik's Cube World Championships held in Budapest, Hungary. He later published his method, known as the Petrus system, on the Internet. It became a fairly popular method among intermediate and upper-level speedcubers, although its more recent use has diminished considerably due to the increased predominance of methods such as ZZ, Roux, and CFOP. Petrus won the 3x3x3 Fewest Moves category at the 2005 World Championships held in November 2005 at Lake Buena Vista, Florida, USA claiming the US$500 prize. He currently (since 1995) resides in SF Bay Area, California, USA. The Lars Petrus System The Petrus System was designed as an alternative to the popular layer-based solutions of the early 1980s. Petrus reasoned that as a solver constructs layers, further organization of the cube's re ...
