Seeing Fang Jun excitedly flipping through the piles of intelligence reports, Li Junxian shook his head and said: "It's all a mess, and there isn't a single useful clue. And even if there is, who can find the useful clues among so much intelligence?"
Which one can you find?"
This is true. Among thousands of pieces of information, trying to find a useful piece of information is like looking for a needle in a haystack.
Li Chongzhen didn't speak, but he looked very sympathetic to Li Junxian.
Just looking at this information makes me dizzy, how can I find it?
Fang Jun is confident.
"I have heard a saying, and the general meaning is that there will not be more than six people between you and any stranger. In other words, you can get to know any stranger through at most six people."
This is the famous "six-dimensional space" theory.
This was put forward by a psychologist in the 1960s. No one knows whether it is correct or not, but many physicists and philosophers believe that this statement is reasonable, at least theoretically speaking.
Liveable.
Everyone has relatives, friends, classmates, and colleagues. Using these people as the base, we can trace the relatives, training, classmates, and colleagues of each of them... This will be an extremely huge number, six times
After that, it will include more than 5 billion people on the earth.
This kind of inference may not be scientific and rigorous enough, and possible repetitions have not been taken into account, but it is enough for understanding the six-dimensional space.
The conclusion of the six-dimensional space also shows that exponential calculation is a terrible calculation, because there are at least fifty people around each person. Using fifty as the base number, it can easily exceed more than a billion.
In India, there is a legend about the Tower of Hanoi: In the holy temple, there are three gem needles inserted on a brass plate. When the Lord God Brahma created the world, he threaded a needle from bottom to top on one of the needles.
There are 64 gold pieces from large to small. This is the Tower of Hanoi. There is a monk who keeps moving these gold pieces. They are asked to move only one piece at a time. No matter which needle it is on, the small piece must be on top of the large one. It is said that when all the gold pieces are moved,
When all the gold pieces are moved from the needle threaded by Brahma to another needle, the world will perish.
So, will it really perish?
The answer is yes!
The Tower of Hanoi problem is a typical recursive call, but no one dares to design the number of layers to 64, because the running time is too long, and if it cannot exit, the computer will crash. The result of this problem is approximately 2 to the 64th power.
If each movement takes 1 second, it will take more than 580 billion years to move these gold pieces, which is longer than the life of the earth...
Of course Fang Jun doesn't need to find so many people. How many people are there in the entire Chang'an City?
He ordered the clerks on duty to clear all three walls and hang them with rice paper. He then ordered the clerks to search by the name of the person on the intelligence information. The information of each suspect was recorded under the name.
There was chaos in the check-in room.
Li Junxian felt that Fang Jun was just messing around. He knew very well what this fool was capable of. Could it be that he was bored and couldn't go home anyway, so he could just torment these scribes?
Li Chongzhen still had an icy face and could not tell what was going on in his heart.
Anyway, neither of them stopped him.
Since there is no clue in this mess, let’s treat the dead horse as a living horse doctor...
Fang Jun looked at the scribes in a mess and continued to instill ultra-modern knowledge: "Don't think that these seemingly messy things are useless. In fact, all the answers are here. What we have to do is to find him in one way or another."
That’s all.”
Li Chongzhen was expressionless, thinking this sentence was nonsense.
Li Junxian sighed, he didn't want to speak at all...
Fang Jun thought to himself and said: "I just taught you the six-dimensional space, so next, I will teach you a new technology that transcends the times - big data! What is big data? As the name suggests, it is a massive amount of information!"
Li Junxian grinned: "Baiqi sent out more than a hundred personnel, mobilized more than fifty spies, interrogated no less than two hundred people, and obtained thousands of pieces of information. It is indeed as you said, this data
, it’s really big…but what use can such trivial things do?”
Fang Jun chuckled: "You didn't know the method back then!"
"Is this such a stupid way to die?" Li Junxian looked at the busy scribes and curled his lips.
"Generalize from enough clues and look for patterns! Among thousands of seemingly disorganized clues, even if only a dozen of them point to a certain place, or even a certain person, that is a very noteworthy phenomenon! In
Coupled with the theory of six-dimensional space, it is easy to find out that certain people or things that seem completely unrelated are actually very closely related!"
Fang Jun looked determined.
How could it not be certain? The FBI monitors targets all year round, collects various intelligence, looks for patterns in the target's daily habits, living habits, and people they come into contact with, and finally finds what they need through the summary of information.
This is the way of big data!
Snowden, the traitor to the FBI, revealed many secrets of his old employer. This most common method of information collection cannot be called a secret at all...
In fact, the core of the so-called big data method is very simple, which is to give up the desire for causality and instead focus on correlation. That is to say, as long as you know "what", you don't need to know "why", and everything will be based on factual data.
!
How could such an advanced method be useless in searching for some clues that were destined to exist in a city of less than a million people in the Tang Dynasty for 1,500 years?
Two hours later, Li Junxian and Li Chongzhen were stunned!
The weapons inspector lost three crossbows. All the people who last came into contact with these three crossbows automatically became suspects. There were seven people in total. Then based on their explanations, who gave the crossbows to them and the people they had daily contact with
, people who are close to them, even relatives from above have recently come to their home...
There are all kinds of things, divided into categories, and clearly recorded on the rice paper on the wall, making it clear at a glance.
One of them, the weapons supervisor and craftsman named Zheng Wu, had the most confusing relationship, but after digging through the details layer by layer, it was finally discovered that all the information about the other two people was summarized in one person.
Chu Yanbo.
After summarizing the data, it can be explained that this is no longer a coincidence. This person must have a huge role in it!
Fang Jun scratched his eyebrows: "Why do you think this name looks familiar?"
Li Junxian looked a little ugly: "Chu Suiliang's son."
"Oh - that idiot!" Fang Jun suddenly realized, thinking that he had had a head-to-head confrontation with that person, but he was tortured miserably by him.
Li Junxian was worried: "This is Chu Suiliang's son! What does he want these three crossbows for? If I remember correctly, that guy is a scholar who has no power to tie a chicken. Is he hunting? But he can't find them either.
His motive for colluding with assassins to assassinate Zhang Shigui..."
Fang Jun blinked and offered his advice: "Isn't it enough to capture him and bring him back for trial? Under three trees, why can't you ask for more?"
Although Chu Suiliang has a good relationship with his father, he is disgusted by the sight of the two fathers. If he can take the opportunity to straighten things out, he will definitely be in a good mood...
"Are you kidding?" Li Junxian was startled and stared: "That's Chu Suiliang's son!"
Li Chongzhen said coldly: "There is no need to capture him. We will send out spies to monitor him closely. At the same time, we will thoroughly investigate who he has been in contact with and who he has been to during these days. Then, if we use this big data method, there will be nothing to hide!"
The reason why I dare not arrest Chu Yanbo is because there is no evidence.
When all the clues are irrefutable, even His Majesty Li Er will not be able to save him!
Fang Jun raised his thumb and said, "You can teach me!"
Then he yawned, stretched, and said: "Hurry and prepare a place for me. You can just do these things. I have to get some sleep..."
Li Chongzhen immediately bowed and said: "I'm humble, go and get ready now!" His respectful attitude was completely different from his previous unruly attitude.
Li Junxian sighed: "You said you thought I had a crooked idea, and it's true! You solved such a difficult thing in a daze. In my opinion, you are more qualified than me to be the commander-in-chief of the 'Hundred Cavalry'
Already..."
Fang Jun was startled and said hurriedly: "It's not easy to say this nonsense!"
Are you kidding? The emperor's spy chief is so easy to be?
Jin Yiwei is so awesome, and I have never seen any of the commanders of Jin Yiwei die a good death. Moreover, the history books say that Li Junxian was unjustly killed by His Majesty Li Er. Who knows if he knew too much, His Majesty Li Er?
