After Liu Hao left, Lin Cheng quickly finished grading the remaining few papers. He was extremely bored, so he turned around in Liu Hao's office.
From beginning to end, his face was filled with a joyful smile.
Being able to reunite with his best friend, Lin Cheng only felt that every cell in his body was filled with joy.
You know, before getting the food delivery system, Lin Cheng's biggest wish, besides making money, was to meet this childhood friend as soon as possible.
Now that his wish for many years is finally time, he is naturally in a good mood.
Now he is even thinking about where he will take Liu Hao to play during these days when Liu Hao is in Jiangcheng.
Anyway, after Chen Feng said hello, Lin Cheng's commute to and from get off work is quite casual now, even if he doesn't deliver food for a year, Meituan will definitely not fire him.
As for the takeaway system?
Anyway, there will be opportunities to trigger system tasks in the future, and ten days and a half months at night is nothing.
After walking around the office for a while, Lin Cheng sat down on the chair again.
He casually took a notebook from the table and read it.
Um?
After seeing the contents of the notebook, Lin Cheng showed a surprised expression on his face.
The four color theorem?
Could it be that Liu Hao is studying this?
In this notebook, Lin Cheng only saw one topic, but there was no proof process below.
The predecessor of the four-color theorem is the four-color conjecture, which is one of the three major mathematical conjectures in the world and one of the three major modern mathematical problems in the world. The content of the theorem is that two straight lines that cannot intersect in a plane and have no common point. Many people have proved that five or more pairwise connected regions cannot be constructed in a two-dimensional plane, but they have not raised it to the level of logical relationship and two-dimensional inherent properties, resulting in many false counterexamples.
The question written in the notebook in Lin Cheng's hand is the process of logical proof of the four-color conjecture.
Seeing the topic on the notebook, Lin Cheng thought to himself, it seems that his friend has a serious heart and wants to climb this difficult problem.
Speaking of it, although the four-color conjecture has been proven, it only used a computer to make tens of billions of judgments, not to give proof skills, it can only be said that it only succeeded on the basis of a huge number of advantages.
Because of this, in the eyes of many mathematicians, the four-color theorem is not so perfect.
They want to prove the four-color conjecture through a rigorous mathematical logic system, but until now, no one has been able to succeed.
Originally, Lin Cheng didn't have much interest in mathematics, but now that he has the ability of a mathematics master, he has a little interest in these world-class problems.
Looking at the notebook in his hand, Lin Cheng remained silent.
Even though he now has the ability of the world's top mathematician, he still feels that he has no idea when faced with the four-color theorem.
Of course, he can also prove it in a conventional way, but Lin Cheng doesn't want to do it, because for so many years, many mathematicians have done it, but none of them succeeded. In other words, they want to solve it in a normal way. If you ask this question, the possibility of success may not be great.
If you want to find a way to prove this problem, unless you find another way.
But how to do it?
Lin Cheng stared at the notebook in his hand, and sat there motionless.
People who don't know what he is doing will definitely think that Lin Cheng is in a daze, but in fact, they don't know that at this moment, Lin Cheng's brain is running crazily, and countless possibilities and ideas of proof are all in his mind. They kept flashing in his mind, but he denied them one by one.
After trying countless possible combinations, Lin Cheng still shook his head.
In his opinion, this four-color conjecture is like a cactus covered with thorns, making it impossible for people to start.
Unfortunately, the knowledge I have acquired is still too little.
Regarding basic subjects, the only skills I know now are masters of mathematics and experts in physics, and my knowledge of hacking can barely touch this.
etc!
Hacker!
Suddenly, a flash of lightning flashed across his mind, and a feeling of enlightenment suddenly appeared in his heart.
He felt that he might be able to use hacker thinking to try to prove the logical relationship of this four-color conjecture.
Just do what you want, without saying a word, he directly picked up this notebook and began to write his own proof process on it.
His writing speed is very fast, judging from his appearance, it seems that he doesn't need to think, and it didn't take long for a page to be full of writing.
At this moment, the office seemed extraordinarily quiet.
Except for the rustling sound of the pen tip rubbing against the paper and the sound of flipping the paper, there is nothing else.
Lin Cheng seemed to have forgotten the change of time.
At this moment, Liu Hao, who was carrying the courier box, had already entered the office. He wanted to say hello to Lin Cheng, but when he saw that Lin Cheng seemed to be insane, he immediately startled her.
He hurried to Lin Cheng's side, wanting to see what Lin Cheng was doing.
It's just that when he saw what Lin Cheng was writing, Liu Hao stood there motionless as if struck by lightning, with a shocked expression on his face.
The proof of the four-color theorem was a subject given to him by his teacher. In his teacher's words, it is best to complete it, and it doesn't matter if it is not completed. It is an eye-opener.
After all, the difficulty of this theorem lies there.
Since he got this subject, he has been studying it for almost three months, and he has used a lot of various proof methods, but none of them succeeded.
But even so, he definitely has a deep understanding of the four-color theorem.
It was precisely because of this that he could tell what Lin Cheng was writing at a glance.
It's just that this made him feel even more shocked. Is the person who is writing hard in front of him still his childhood friend?
Although there is a saying that people should treat each other with admiration for three days, Lin Cheng's changes are too great, right?
From his eyes, it can be seen that Lin Cheng is not writing nonsense at all, but really has ideas and ideas.
What made him even more excited was that Lin Cheng's method of proof was not at all a conventional method of proof that he knew.
Could it be that he found a new way of proof?
Thinking of this, an excited expression appeared on Liu Hao's face.
At this time, Liu Hao was not going to interrupt Lin Cheng anymore. He could see that Lin Cheng had already entered a strange state. Once he was interrupted, maybe even the idea of ??proof would be planned. .
Liu Hao was gradually attracted by Lin Cheng's proof method, but as time passed, as Lin Cheng's proof process continued to deepen, Liu Hao's brows gradually frowned,
Because he found that he couldn't understand Lin Cheng's proof process, and the various logical relationships involved in it were too complicated and too profound.
He felt that the computing power of his brain had reached its limit, perhaps because of excessive brain use, and he even felt dizzy in his brain.
Liu Hao shook his head vigorously, trying to wake himself up.
When he looked at Lin Cheng again, his eyes seemed to look at another monster. (Remember the site URL: www.hlnovel.com - Didn't finish reading?
