When Cheng Lin got the news, he was meditating on the deck.
In order to find He Jian in time, he practiced very "shallowly", so after catching the relevant keywords, he quickly opened his eyes.
"What happened? What's stuck?"
Cheng Lin asked.
The little logistics leaders came over with an incomprehensible expression and said, "It's the progress of deciphering. I've been using computers to decipher it before, and the progress was very fast, but now, it's suddenly stuck."
its stuck?
Cheng Lin looked puzzled and asked a few questions carefully before understanding the situation.
It is indeed stuck.
The deciphering started in the evening. It was initially calculated locally by the computer. After about an hour of sampling in the early stage, the calculation began quickly, and the deciphering progress also increased rapidly, reaching 30% in just one hour.
After exceeding this value, the decryption speed suddenly dropped sharply. The researchers came up with the answer that the local computing speed could not keep up with the computers that could be moved to the island, and there was no way to connect to the Internet. So after thinking about it, they chose another option.
A train of thought.
An optical cable was moved from the Magic City to connect several cameras, and the dynamic images on the stones were transmitted to the Magic City through data, and then analyzed by the institute's supercomputer.
This is troublesome and labor-intensive, and the cost is also very high, but for national action, this cost is negligible, and there is no need for major departments and bureaus to take action. Professor Wu alone can handle it.
This allows image data to be transferred to the institute.
It is indeed impossible to use wireless network in the projection, but we can always pull a network cable through it, right? Instead of uploading to the cloud, we only use local transmission. I tried it and found that it works, but it seems to be interfered by the projection. Even if it is wired transmission, other
The data transmission speed is also much slower, and there are occasional interruptions.
But it doesn't matter, this is within the acceptable range.
With this "probe", the research institute in Shanghai suddenly became busy.
Not only the Magic City, but all supercomputers nationwide have been turned on.
For example:
"Sunway & Taihu Light" has a linpak floating point performance of 93pflops, a theoretical floating point performance of 125.4pflops, and a theoretical performance of up to 1 billion supercomputing operations.
"Th-2 Tianhe-2" has an entire computing array with up to 4,981,760 processors and a peak speed of up to 33,862tflop/s.
…
This belongs to the Xia Kingdom. On a global scale, the exploration of major projections has also reached the stage of decryption.
For example, the federal Summit, currently ranked the number one supercomputer in the world, and Sierra, which serves the National Security Agency, have been temporarily mobilized to decipher the Immortal Code.
…
With the help of supercomputers, the deciphering progress rose like a rocket. Everyone was originally very excited, but when the deciphering progress exceeded 50%, the computing speed obviously dropped to a certain extent.
After 70%, the speed drops again.
After 80%, the speed becomes slow.
After 90%, it stops completely.
…
Yes, stop, supercomputer data simulation can no longer give the answer.
Not only the Xia Kingdom, but also the Federation’s supercomputers and the world’s decipherers received a wake-up call!
Humans originally thought that the passwords left by the immortals were vulnerable to computers, but reality slapped them hard.
…
"It has been an hour. For a whole hour, the breakthrough progress has been stuck at 90%. There has been no breakthrough. The experts who have gone ashore and back have 11 waves. Although we can't go to the center of the island, we can guess, then
I guess it’s already in chaos.”
The little lapel from the logistics department shook his head and sighed.
Is that so... supercomputers are stuck? So powerful? Is it true?
Cheng Lin was a little confused for a moment. It was not true. He thought that no matter how good He Xianren was, his password would not be able to withstand the attack of the computer, but the reality did not seem to be as he expected.
"It took Yu Fu and I three or four months to barely reach 50%. By then, it was extremely difficult for me to break through. The computer is really powerful. It only took a few hours to decipher 90%...
…However, I got stuck, it’s interesting.”
Cheng Lin thought silently in his heart.
He stood up and said, "I'll go take a look."
"Give you a flashlight."
…
After getting off the boat, Cheng Lin ran towards the center of the island with a flashlight.
Six hours passed, and it was already early morning.
For many night owls and immortal cultivators, the early morning is just the beginning of nightlife, but for several major departments, this night will obviously last all night.
The island fell into darkness, and the shadows of the trees stretched out their branches like ghosts.
Cheng Lin didn't care at all and just ran. Soon, he walked along the stone steps, crossed the square, and arrived at the back mountain.
The back hill is brightly lit!
A huge cable stretches from the island to the island in the middle of the lake.
Surrounding "Senior Cheng" who was sitting cross-legged, several cameras were pointed in various directions. Next to him, there was a group of scholars in white coats who were busy talking with computers, equipment, pens and notebooks.
This place was temporarily set up as a field research institute, with tables and benches all available.
The little lapels were almost all on the shore, busy, meditating, or talking in low voices. The atmosphere in the entire valley was depressing.
"Cheng Lin? Come over here."
Sun Xiao had sharp eyes. When he saw him returning, he waved his hand and shouted in a low voice.
"We're here, how are you? I heard it's stuck?" Cheng Lin came over and sat down cross-legged.
Fu Zhongting next to him had a sad face and nodded: "Yes, it has been stuck for an hour. I don't know what happened, but the super computer can't break it."
"Is there any specific reason?" Cheng Lin asked curiously.
Xie Qingke, who was sitting cross-legged in meditation, opened his eyes and glanced at him, "We don't know, and we don't dare to ask."
"...I'll ask elsewhere."
Cheng Lin shook his head, thought for a while, and ran to the Second Division, ready to ask Liang Pi, who seemed to be able to talk to the higher-ups.
There were many "photothermal furnaces" burning on the entire back mountain, which were quite bright. Cheng Lin walked through the crowd of people sitting cross-legged and meditating. When he turned his head, he could see the sweaty and busy staff at the front of the lake.
The heads of the four departments and bureaus, as well as many deputy heads, seemed to be discussing something, and the atmosphere was very dull.
…
"Cheng Lin?" At the Second Division station, Liang Pi was slightly surprised when he saw Cheng Lin coming, and then smiled and said, "You are here to inquire about the news, right?"
Nodding, Cheng Lin did not hide anything and asked seriously: "Do you know the inside information? Why are you stuck?"
Liang Pi sighed and handed Cheng Lin a small futon. After he sat down, he whispered: "Actually, it's not that the computer is stuck, but 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 Senior Cheng obviously requires finding the pattern, then condensing the aura field, driving stones, and completing the scattered field structure. The difficulty lies in finding the pattern.
law."
"The human brain is limited. Except for a few practitioners who have improved their brain thinking, no one else can compare with computers in terms of computing speed, let alone supercomputers."
"The essence of computers is to find patterns, then give limited possibilities, sort these possibilities, and let our people condense the field and try them one by one."
At this point, Cheng Lin tentatively said: "Similar to the exhaustive method?"
Liang Pi nodded: "It's not quite accurate, but it probably means this. In the first 90%, the possibilities given by the computer are limited. We only need to send people to try one after another, but when it breaks through 90%... it may be
Sex reaches an almost 'infinite' amount, so... we're stuck."
After a pause, Liang Pi smiled bitterly, "If the direction of deciphering is compared to the future, then there are a million possibilities for these laws at every moment."
"If we calculate the total number of cycles, the 'possibilities' are as many as trillions, ten trillions, trillions... countless, like the number of sands in the Ganges, endless!"
"To give you a more popular metaphor, you have read Liu Cixin's "Poetry Cloud". Li Bai used a quantum computer to perform the ultimate poetry recitation and weaved a huge and magnificent poem cloud. It exhausted the arrangement of words. In the poem cloud
There must be a masterpiece of poetry hidden away, but... no one can find it!"
Liang Pidao.
Cheng Lin was silent.
He has understood that there is no problem with the supercomputer, which has successfully displayed the possibility of the changing pattern of fairy stones. However, after 90%, there are too many possibilities, almost endless, and people cannot find the correct one at all.
Unless it takes a huge amount of time and manpower to try them one by one.
But... projection has a time limit!
If you delay for too long, wait for the projection to disappear...
Cheng Lin suddenly understood and looked up at the stars.
He thought of Yu Fu and the great swordsman.
When human beings face the mystery of immortals, they encounter the same difficulties as Yu Fu and others.
