Puzzle SVG is not an easy task, which usually requires intelligence, rather than high-level specialized knowledge.
Nevertheless, some puzzles stimulate theoretical and practical developments of scientists. So, for example, the number of possible different states of the Rubicaravno cube (8! × 38 – 1) × (12! × 212 – 1) / 2 = 43 252 003 274 489 856 000, that is more than 43 quintillion combinations. Despite this, it is known that from any state of the cube can be collected in no more than 20 moves. In other words, the so-called God’s algorithm will not make decisions longer than 20 moves.
Puzzle SVG History
Some puzzles have been known since ancient times. Original logical problems are found on the walls of Egyptian pyramids, in ancient Greek manuscripts and other historical monuments. The heyday of the medieval history of puzzles can be considered the end of IX century. Rising levels of education and declining religious intolerance towards the sciences have led to an expansion of the circle of lovers of logic. At this time, the first book of puzzles in Europe – a collection of Irish educator Alquin “Tasks for the development of young minds.
The Puzzle SVG were most widely used at the turn of the XIX and XX centuries. Thanks to the activities of the American Sam Loyd and Englishman Henry Dudley puzzles have penetrated into many periodicals, became popular among the general public. Lloyd was long considered the author of the world’s most popular puzzle “Pyatnashki” (actually invented by Noah Palmer Chapman of Canastoty). The puzzle was so popular that some employers had to order a ban on bringing it to work.
The next push in the development of puzzles was the invention of the famous cube by Hungarian Ernő Rubik in 1974. The Rubik’s Cube has become not only a toy, but also a research object for mathematicians and engineers. Since then, high-speed cube assembly competitions have been held around the world on a regular basis. The modern puzzle industry is developing rapidly. New games, constructions and editions are constantly appearing on the market to keep the human intellect in tune, develop logic, train non-standard thinking and raise the intellectual level as a whole.
Since 1992, the World Puzzle-Sport Championships have been held, an intellectual type of competition in which participants compete in high-speed puzzle solving on paper.
Famous puzzle creators
The most famous creators of the puzzles are Henry Ernest Djudeny, Sam Lloyd, Martin Gardner, Erno Rubic and Oscar van Deventer.
Erich Fridman, a professor of mathematics from the USA, is also known for his puzzles on paper and as the author of puzzle sport tasks for the World Championships. One of the most famous creators and promoters of puzzles, the author of hundreds of versions of puzzles and the author of 80 books on puzzles – Japanese Nob Yoshigahara.
