End of Round Five
Why this question ?
Just something to wander about.
My view:
Even if all combinations can be calculated, which takes more computing power than the supercomputers have used, it is still problematic to decide which one to use. Humans follow their “gut feeling” or intuition and therefore can skip the hard part of computing. It is the power of pattern recognition and creativity and illogic.
And sometimes simply a mistake by making a move that is not any good. But that just might throw the computer off his calculated path, as the move creates a lot of other possible paths to win and it just might make a wrong choice there and follow the wrong way.
So the point is that tester needs to be creative and follow his/her intuition, but also needs to know the technology very well.
Before the discussion the answer nr. 11 was voted the best.
The following are all the answers I received :
(Spelling not corrected. )
Tester 1:
Because computer cannot solve problems creatively, it’s only have behavior instructions.
Tester 2:
Expert players can win chess games against supercomputers with creative approaches to standard problems and using their advanced pattern recognition skills.
Chess supercomputers achieve their results by combining raw computing power with game-board evaluation algorithms. These algorithms use a database of historic chess games as an input for the game-state evaluation. Due to the extremely high number of possible permutations in an average chess match, there is an infinite number of possible matches and therefore the database can never be complete. When the expert player comes up with a creative game plan, that the computer cannot define using its database, it has to rely on raw computing power in order to calculate the next move. Humans are equipped with a great pattern recognition ability which renders their game-state evaluations infinitely more effective in terms of raw calculation.
Tester 5:
A machine does not have any flexibility of thinking. The main advantage for a human is a feeling for the game. Quite often, human cannot calculate everything, but he makes the right move because he feels it is the right move. A computer can only try to make the right move mathematically.
Tester 6:
Possible explanations:
1.Chess software run by supercomputers have issues.
2.Expert players have better knowledge of chess if chess software developers.
3.Expert players have better knowledge of chess if chess software testers.
Tester 9:
Computers always follow a logical pattern, while humans can act illogically on the same situation.
This means humans are able to take actions (without knowing the results) and adopt to the new situation, while machines have to calculate every step and its consequence.
Tester 10:
All possible movements and combinations should be tried or tested to be certain of supercomputer win at all the time.
However it can not be achieved because there are about 10^120 different movements in chess and it would take (if supercomputer used with billion calculations a second) 30^103 years to complete it.
Tester 11:
Supercomputers like all the computers are following the path they are told. Although they are able to predict a number of scenarios, they do it through the algorithms specific to their goals. Expert players though have the unique opportunity to use their imagination that might not take them to their goal at first sight. These unexpected behaviours that might have no logic in them, can be done only by human mind and imagination. Following the unexpected path might have unexpected results every now and then. Thats tha advantage of the human mind.
