Establishing a mathematical model for this information security to decipher the other party's encrypted messages Zhang Weiping never gave up.
Because there are countless variations in both functions and algorithms, it is far from enough to rely solely on manual deciphering and calculation.
The most important thing about information is real-time.
Especially under the current circumstances, if the encrypted message cannot be deciphered in time, it will not be of much value.
Because even if it was deciphered later, their activities and information transmission would have been over long ago.
But it is not that easy to establish a mathematical model for an unknown mathematical law.
If you want to model, you must first understand the actual background of the problem, clarify the purpose of modeling, collect various necessary information, and try to understand the characteristics of the object.
Then, based on the characteristics of the object and the purpose of modeling, necessary and reasonable simplification of the problem is made, and assumptions are made in precise language.
Then analyze the cause-and-effect relationship of the object based on the assumptions made, and use the inherent laws of the object and appropriate mathematical tools to construct equations or other mathematical structures between various quantities.
It is usually difficult to establish a mathematical model for a problem, let alone the encryption method specially designed by the first area.
On the balcony on the second floor, Xu Jianguo popped his head and looked over in surprise. There was still a little sawdust in his hair, and he seemed to be repairing something.
And as my colleague just said, cultivating a group of mathematicians in the field of information security is essential for a big country.
"Chuan'er!" The woman stood up in surprise, wiped the water stains on her hands on her clothes, and a touch of surprised joy appeared in her pupils.
Thinking of this, Zhang Weiping frowned slightly.
Xu Chuan shouted, with tears in his eyes. After several years, he finally saw his parents again and stood in front of them in person again.
Xu Chuan raised his head and shouted, and received an immediate response. At the same time, another little head popped up on the balcony.
Xu Chuan got out of the car and looked at the newly built cement road at the entrance of the village, feeling a little excited and a little nervous.
As for the sixty training seeds, there is no need to pay fees, they are selected by the Mathematical Society.
The formerly lively campus has become a bit deserted these two days. The first and second grade students have left, leaving only the third grade students still hanging on.
After all, food and accommodation are centrally managed by the Olympiad Committee of the Mathematical Society, and money is still needed.
The registration conditions are set at the national second level that competes in the national finals every year, and a certain amount of national training fees need to be paid.
"However, if these functions and algorithm questions parsed from encrypted messages are put into training camps such as the National Data Competition and Modeling Competition, it will affect the training effect."
Therefore, extending the national training time for a period of time is indeed a feasible method.
If they get excellent results in the training and examinations of Guoji, they may be spotted and admitted by top universities, and they can also get extra points in the college entrance examination.
The familiar buildings and farmland on the concrete roadside seem to have never changed, they have always been the same as in the memory.
"It seems this method won't work."
Xingcheng, City No. 1 Middle School.
After a bumpy journey that took nearly three hours, the bus finally stopped at the edge of the national highway.
"You kid, why didn't you call in advance when you came back?"
Because in addition to the training camp for National Congress members, the annual National Congress is the same as the Golden Autumn Camp of the two top universities. You can actually register and pay to participate.
After packing his clothes and books, putting on his schoolbag and a black suitcase, he got on the bus to Yue County.
The advantage of this is that it will not delay other students from taking the college entrance examination.
Although there is a fee, this is a good opportunity for those contestants who have not been able to enter the national competition.
Zhang Weiping was stunned for a moment and clapped his hands fiercely: "Why didn't I think of this? This method is completely feasible."
Wu Lian complained excitedly, and without any explanation she snatched the suitcase's lever from Xu Chuan's hand, turned around and shouted towards the two-story old red brick house: "Old Xu, Old Xu, hurry up
Go buy a fish and an elbow and come back, your son is back."
Zhang Weiping expressed his thoughts, and the mathematics professor looked at him in surprise.
Zhang Weiping shook his head, temporarily put down the thoughts in his mind, and prepared to pack up the information and leave.
Xu Xiao poked his little head out on the balcony and shouted excitedly, then there was a thumping sound coming downstairs, and he rushed over and hugged Xu Chuan's arm.
"Huh? Chuan'er is back?"
"Mom, I'm back!"
"dad."
The training time for the National Mathematical Olympiad Team is generally in March every year.
However, you have to consider and calculate how long it needs to be extended to not delay the training effect.
Sponsored by the Mathematical Society Olympiad Committee, the training lasts for fifteen days, which is half a month.
Xu Chuan responded one by one, and not long after, he had already arrived at the door of his house.
Dragging his suitcase, Xu Chuan took a deep breath and set foot on the road home.
Crowds of people rushed to their dormitories carrying schoolbags, and Xu Chuan was no exception. He hadn't been home for almost half a year.
Whether it is a mathematics Olympiad or a modeling competition, the ultimate goal of students participating in these competitions is to get a good ranking in these world-wide competitions, so as to have the opportunity to enter a higher platform for study.
A mathematics professor next to him saw him stunned for a long time and curiously asked what was wrong.
On the familiar cement floor, a middle-aged woman was squatting by the well and doing something busy. She seemed to sense something. She raised her head and looked around, and then she was pleasantly surprised.
They need more information and data.
"Brother, you are back."
But today is the last day.
This is a so-called resurrection match for some students who devoted themselves to the competition but failed in the exam.
In half a month, two screenings were conducted to turn the original 60 training seeds into six national team members, and then train these six seeds to participate in the IMO competition.
After the head teacher of each class explained the holiday matters, the classroom suddenly burst into cheers.
He cannot delay the future of these students just for the sake of deciphering information.
Along the way, from time to time, villagers who were preparing for the New Year or basking in the sun at the door greeted him and asked with a smile whether the future university student was back.
The 21st century has already entered the information age, and there is no doubt that various algorithms and encryption programs are important to information security.
"Hey, I thought it was something. You can just extend the training time for the national gathering and modeling competition for a while."
"How long has Xiaoxiao been on vacation?" Xu Chuan smiled and touched his little sister's head. This follower who had been sticking to his butt since childhood has grown up.
"It's been almost ten days. Brother, you've grown a lot. Have you taken hormones?"
Xu Xiao looked up and looked at Xu Chuan, who was almost a head taller than her, with wide round eyes, feeling a little incredible.
Obviously there wasn't such a big gap between the two of them last time they met.
