"The decipherment progress is stuck!"

When Cheng Lin got the news, he was meditating and practicing on the deck.

In order to find He Jian in time, he practiced very "shallowly", so after capturing the relevant keywords, he quickly opened his eyes.

"What happened? What's stuck? ”

Cheng Lin asked.

The logistics lapels came over, looking inexplicable, and said: "It's the progress of decipherment, I have been using computers to decipher it before, and the progress is very fast, but now, it is suddenly stuck." ”

Stuck?

Cheng Lin looked puzzled, and asked a few words carefully before understanding the situation.

It's really stuck.

The decipherment began in the evening, initially by the local computer calculation, after about an hour of sampling in the early stage, the calculation soon began, and the decipherment progress also climbed rapidly, reaching 30% in just one hour.

After breaking through this value, all of a sudden, the decipherment speed plummeted, and the researchers came up with the answer that the computers that could be moved to the island could not keep up with the local computing speed and could not connect to the Internet, so after thinking about it, they chose another way of thinking.

A fiber optic cable was moved from the magic capital, connecting several cameras, and the dynamic images on the stones were transmitted to the magic capital through data, and then analyzed by the supercomputer of the research institute.

This is troublesome and laborious, and the cost is also very high, but the national action, this cost is negligible, and it is not necessary for the major departments to take action, just Professor Wu can do it.

This makes it possible to transfer the image data to the institute.

It's true that you can't go wireless in the projection, but let's pull a network cable to go over, right? Don't upload to the cloud,Just go local transmission,Try it,Found that it works,It's just that it seems to be interfered by projection,Even if it's wired transmission,Its data transmission speed is much slower,Occasionally, there are interruptions。

But it doesn't matter, it's within the acceptable range.

With this "probe", the research institute of the magic capital suddenly became busy.

Not even just the magic capital, but supercomputers across the country have been turned on for it.

For example:

"Sunway TaihuLight" has a Linpack floating-point performance of 93PFLOPS, a theoretical floating-point performance of 125.4PFLOPS, and a theoretical performance of 1 billion petascale supercomputing.

"TH-2 Tianhe-2", the entire computing array, up to 4,981,760 processors, with a peak speed of up to 33,862 TFlop/s.

……

This is the Xia Kingdom, and on a global scale, the exploration of major projections has also reached the stage of decryption.

For example, Summit, the federal, currently the world's No. 1 supercomputer, and Sierra, which serves the National Security Agency, have been temporarily mobilized to decipher the fairy code.

……

With the help of supercomputers, the decipherment progress went up like a rocket, and everyone was excited at first, but when the decipherment progress exceeded 50%, the calculation speed dropped significantly.

After 70%, the speed drops again.

After 80%, the speed is slow.

After 90%, stop completely.

……

Yes, stop, the data simulations of supercomputers can no longer give answers.

Not only the Xia Kingdom, but also the supercomputers of the Federation, the decipherment of the world has ushered in a slap in the face!

Humans thought that the password left behind by the immortals would be vulnerable in front of the computer, but reality slapped them in the face.

……

"It's been an hour, a full hour, the progress of breaking through the border is stuck at 90%, and there is no breakthrough, there are 11 waves of experts who go ashore and go back and forth, although we can't go to the center of the island, we can guess that it is estimated that there is chaos over there."

The logistics little lapel shook his head and sighed.

Is that so...... Supercomputers are stuck? So powerful? Really?

Cheng Lin was a little confused for a while, unreal, in his mind, no matter how He Xianren is, his password will not be able to withstand the computer's attack, but the reality does not seem to be as he expected.

"It took me three or four months to barely reach the early 50%, and by then, it was extremely difficult for me to break through, and the computer was really powerful, and it only took a few hours to decipher 90%...... However, it is stuck, which is interesting. ”

Cheng Lin thought silently in his heart.

He got up and said, "I'll go and see." ”

"I'll give you a flashlight."

……

Getting off the boat, Cheng Lin ran wildly towards the center of the island with a flashlight.

Six hours had passed, and it was early in the morning.

For many night owls and cultivators, the wee hours of the morning are just the beginning of the nightlife, and for several major bureaus, this night is obviously going to be all-nighter.

The island was plunged into darkness, and the shadows of the trees stretched out like ghosts.

Cheng Lin didn't care, just ran, and soon, he walked along the stone steps, through the square, and came to the back mountain.

The back mountain is brightly lit!

A huge cable pulls from the island to the island in the middle of the lake.

Sitting cross-legged, several cameras were pointed in all directions, and a group of scholars in white coats were busy talking with computers, equipment, pens and notebooks.

The place was temporarily set up as a field research institute, with tables and benches.

The little lapels are almost all on the shore, busy or meditating, or whispering, and the atmosphere of the whole valley is depressing.

"Cheng Lin? Come over here. ”

Sun Xiao's eyes were sharp, and when he saw him returning, he waved his hand and shouted in a low voice.

"How's it going? Heard of the card? Cheng Lin walked over and sat down cross-legged.

Fu Zhongting next to him made a bitter face and nodded: "Yes, it's been stuck for an hour, I don't know what's wrong, the supercomputer can't even break it." ”

"Is there a specific reason?" Cheng Lin asked curiously.

Xie Qingke, who was meditating cross-legged, opened his eyes and glanced at him, "We don't know, we don't dare to ask." ”

“…… I'll ask somewhere else. ”

Cheng Lin shook his head, thought about it, and ran to the second division, ready to ask Liang Pi, who seemed to be able to talk to the high-level.

There are a lot of "light and heat stoves" lit on the entire back mountain, which are quite bright, Cheng Lin walked through the crowd of people meditating cross-legged, and when he turned his head sideways, he could see those sweaty and busy staff, at the front of the lake, the heads of the four divisions, and many deputy directors were gathered together, as if they were discussing something, and the atmosphere was very dull.

……

"Cheng Lin?" At the station of the Second Division, Liang Pi was slightly surprised when he saw Cheng Lin coming, and then smiled, "You are here to inquire about the news." ”

Nodding, Cheng Lin didn't hide it, and asked seriously: "Do you know the inside information?" Why is it stuck? ”

Liang Pi sighed, handed Cheng Lin a small futon, and waited for him to sit down before whispering: "Actually, it's not that the computer is stuck, it's that we are stuck." ”

"What do you mean?" Cheng Lin raised his eyebrows.

Liang Pi sighed again, and said with a wry smile: "The puzzle left by Cheng seniors obviously needs to find a pattern, and then condense the aura field, drive into the stone, and complete those scattered field structures, the difficulty lies in finding the law. ”

"The human brain is limited, except for a few practitioners who have strengthened their brain thinking, no one else can compare to a computer in terms of computing speed, let alone a supercomputer."

"The essence of computers is to look for patterns, and then give limited possibilities, rank these possibilities, and let our people condense the field and try them one by one."

Speaking of this, Cheng Lin said tentatively: "Similar to the exhaustive method? ”

Liang Pi nodded: "It's not accurate, but it's probably what it means, the first 90%, the possibilities given by the computer are limited, we just need to send people to try in turn, but when it breaks through 90%, ...... The possibilities reach an almost 'infinite' amount, so ...... We're stuck. ”

After a pause, Liang Pi smiled bitterly, "If the direction of decipherment is compared to the future, then the 'possibility' of these laws, in every moment, has a million possibilities. ”

"If you count the total number of cycles, then the 'possibilities' are as many as trillions, ten trillions, trillions...... Innumerable, like the sand of the Ganges, endless! ”

"To give you a more popular analogy, have you read Liu Cixin's "Poetry Cloud", Li Bai used a quantum computer to carry out the ultimate poetry, weaving a huge and magnificent poetry cloud, which exhausts the arrangement of words, and the poetry cloud must hide the pinnacle of poetry, but ...... But no one can find it out! ”

Liang Pi said.

Cheng Lin was silent.

He had already understood that there was no problem with the supercomputer, and it had succeeded in showing the possibility of the change law of the fairy stone, but there were too many possibilities after 90%, almost endless, and people could not find the right one from it.

Unless, with a huge amount of time and manpower, try them one by one.

But...... Projection has a time limit!

If you delay it too long, wait for the projection to disappear......

Cheng Lin suddenly realized and looked up at the starry sky.

He thought of Yu Fu and the Great Sword Master.

Faced with the puzzle of the immortals, humans encountered the same problem as Yu Fu and them.

"We don't have time!"
