Building a computer program to remedy a chess hassle known as the Queens Puzzle ought to win you a prize of a million bucks, say scientists who have thrown open a task that they declare impossible to crack.

Devised in 1850, the Queens Puzzle challenged a player to locate eight queens on a preferred chessboard so that no two queens may want to attack each other differently. This means putting one queen in every row so that no queens are inside the identical column and no queens are inside the same diagonal.
Although people have solved the hassle, once the chessboard increases to a large size, no computer program can resolve it. Researchers from the University of St Andrews in the UK accept that any program that can crack the famous “Queens Puzzle” would be so powerful that it could remedy impossible duties, such as decrypting the toughest safety on the net.
They determined that when the chessboard reached 1,000 by 1,000 squares, laptop programs could no longer deal with the good Scientists’ number of computer alternatives and sunk into a doubtlessly everlasting battle challenge.
The conflict corresponds to the fictional “top-notch computer” Deep Thought in Douglas Adam’s popular sci-fi collection, the Hitchhikers Guide to the Galaxy, which took seven and a half a million years to answer the Meaning of Everything, researchers stated.
Suppose you can write a PC program that might resolve the hassle fast. In that case, you may adapt it to determine the maximum vital problems that affect us all daily,” stated Ian Gent, the professor at St Andrew’s.
This consists of trivial challenges like running out the most important institution of your Facebook pals who do not recognize every different or essential one like cracking the codes that preserve all our online transactions safe,” Get introduced.
Do you face performance issues with your laptop or PC? Is your computer getting slower and slower to boot up and work on? If yes, read on for a few tips on how to make your computer faster.
Here goes:
1) There is no need to retain unused programs. So uninstall them.
So how do you do that? Open the Control Panel’s “Program and Features” page and review the installed software list. Be careful to leave your computer’s hardware needs, the publisher listed as PC maker’s name or Microsoft.
2) Removing temporary files, including internet history and cookies, should give you much hard disk space, speeding up your PC. Open “My Computer,” select your hard drive. Usually, C:/, select the Windows folder and open the folder titled “Temp.” Select all the files older than the current date and press the delete key. Then go to Recycle Bin on your desktop and empty it.
3) Even if you clean out all your temporary files regularly, if your hard disk becomes 85% full, it will slow your computer’s speed. If you film videos or use your PC to record television, you will want a hard drive above 1TB.
4) Preventing unnecessary startups will speed up the time for the laptop or PC to boot up. Many of the programs launched on startup continue to run and use up your computer’s memory. To prevent the programs from running, click “Start” and then type “Run” in the search box, click “Enter,” and then type “MSConfig” and press enter. You should see the startup tab with the programs ticked, which will load when your computer starts. You may be surprised at what you find because they may not have been within your knowledge. Click “Disable All,” and then, if needed, select the ones you want to run at startup, such as antivirus software.
Another way to boost startup is to remove all unnecessary fonts and Windows loads. Windows 7 loads more than 200 fonts on startup, which can slow the rate of the bootup. Go to the Start Menu’s search box, type “fonts,” and in the “fonts” folder, check off all the fonts you don’t want, and click the “Hide” button in the toolbar.
5) Getting more RAM, known as Random Access Memory, can speed up your computer. It is the temporary storage memory used by your computer when different programs execute tasks. If you don’t have enough RAM and use many programs, your computer will run slowly. There is no theoretical upper limit on the amount of RAM you can have with a 64-bit operating system, but in practicality, 4 GB is more than enough for most people.
6) Windows includes a built-in disk de-cluttering tool called “Disk Cleanup” for speeding up performance issues. Open Disk Cleanup by clicking “Start>All Programs>Accessories>System Tools> Disk Cleanup. Summing up, these are some of the great ways to boost the performance of your laptop or PC, and by implementing them, you will get positive results.
Rosina S Khan has authored this article highlighting ways to speed up your computer. Researchers said those issues are hard for PC programs because there are so many alternatives to keep in mind that it may take many years. This is due to a procedure of “backtracking,” an algorithm used in programming wherein every possible choice is considered, after which “backed away” until the correct answer is found, they stated.
However, that is all theoretical; no person has ever come close to writing a program that could resolve the issue quickly. So what our studies have proven is that for all realistic functions, it can not be done,” said Peter Nightingale, a senior studies fellow at St Andrew’s. The prize money of 1,000,000 USD, presented utilizing Clay Mathematics Institute within the US, is to be had by all of us who can remedy the puzzle. The look was published in the Journal of Artificial Intelligence Research.
