A new type of computer, which is equivalent in the meaning of calculation capability with a quantum computer, is put into practical use in Japan.

As far as processing "Combinatorial optimization problem" is concerned, the quantum computers are already developed in the level of practical use by a Canadian venture company. It is a task to choose most appropriate solution among a huge amount of number pairs. However, a Japanese manufacturer, Fujitsu has developed a new type of computer which can solve the Combinatorial optimization problem using only traditional electronic circuits. They started to provide the services using it, and the most significant feature of this computer is that it doesn't require a huge equipment to keep their components in ultralow temperature.

According to the Fujitsu, it might be utilized for the tasks such as making parcel service more efficiently, through assisting finding out the best traffic route for delivery. It might be also utilized for finding out the best angle to expose a cancer patient to a laser beam, taking a radiation therapy. The company aims to make this new type of computer to grow hundred billion yen business until the year of 2020.

The school did not succeed in recruiting a new English teacher before the school year started. As a side note, the Japanese school year starts in April. From the beginning of this month, other English teachers are teaching the students, doing double duty with their own classes. The Educational Commitee of Matsui city announced that they will find a new English teacher until the middle of this month.

We will do our best that it doesn't happen again."

A Japanese man named Yuki Yamamoto, won four awards for solving Rubik puzzles blindfolded in Rubik's Cube's contest which was held in Japan last winter. He even made a record to memorize the color arrangement of 25 Rubik's cubes in one hour and solved 24 of them blindfolded!

At first he looks at a Rubik's cube for 11 seconds memorizing the color arrangement of them, then wears a blindfold and solves it in 22 seconds. How could he memorize a disordered color arrangement for a Rubik's cube in such a short period of time?

Yamamoto memorized the important algorithms in solving a Rubik's cube. According to Yamamoto, he converts the positions of cube cells into ‘hiragana’, a type of Japanese writing.  Each cell address is assigned to one hiragana letter, then each actual cell position on the disordered cube is also assigned one hiragana letter.  In short, every color arrangement is expressed by a combination of "original address" and "current located position".  So if a Rubik's cube has 9 cells on one face, he can express the situation on the cube by a string of approximately 20 Hiragana letters.

However, it isn't an easy task memorizing a string of 20 meaningless letters in a moment.  However, there is more to this.  He makes a breakdown of those letters into pairs of 2 letters, so that he can make Japanese words which consist of two hiragana letters, or words that have 2 syllables.  Because hiragana is syllabic letter, every single letter is equivalent to one syllabic sound.  For example, you can make a Japanese sentence that consist of 2 words by 4 hiragana letters, such as "Ka-ki (o) ni-ru", or "I cook a persimmon". The sentence will be converted into visual and specific images which makes it easier to memorize.

As a result, there should exist a total of 500 patterns of 2 hiragana letter pairs used for solving a Rubik's cube.  He had memorized, by spending a lot of time in advance, learning these patterns. He also had memorized several hundred algorithms for changing the order of one cell, without interfering with the other cells. When solving the puzzle, he only has to evoke his memories and apply them.
