Update in the middle of the night, don't you reward comrades who pass by.

Looking at everyone, Liu Yuan shook his head regretfully and said, everyone pay attention to the German students at the door, have the people thought about it, why would they rather stand and listen to such a class, have you thought about it?

At this time, the classroom was unusually quiet, and many students remembered that there were several Germans standing outside the window.

Liu Yuan stepped down from the podium, "The root of the Chinese's inferiority lies in his fear of new things, and it is precisely this that has stopped China for a long time. I thought you were all young and receptive to new things, but you actually disappointed me.

The chief of staff of Zuo Quan thought that operations research was a very important subject, and he even thought that he would influence the future pattern of battles, and he was afraid that one day others would learn it, and the descendants of his inventors would know nothing, and the enemy would beat us to the ground with the knowledge we had created, just as the British Empire used gunpowder to bring China, the ancient inventor of gunpowder, to its knees.

So he would rather bear the infamy of selfishness than let German students into his classroom, but what about you? What are you doing! You have made the instructors who have hoped for you choose to give up, you are a shame to the whole country and the nation, and it is nonsense for me to say at the opening ceremony that you are the pillars of the country! ”

Liu Yuan scolded hoarsely, he finally knew what the real historical record of the Wuhan branch memory of the Wuhan branch was, they were all this kind of people, what could be recorded. "Headmaster, don't talk about it, please teach us, if we can't learn, we are willing to commit suicide to thank the countrymen." A boy said to Liu Yuan with tears in his eyes. "Headmaster, teach us quickly, if we can't learn, we are willing to commit suicide to thank the countrymen." More tearful students stood up. "It seems that you are not all waste, I will do my best to teach you this subject, and if there are any students who think what I said today is too much, I apologize to you." After speaking, Liu Yuan bowed and continued.

Speaking of military operations research, it is a subject independently developed by the Republic of China itself, and it is a bit ridiculous to say, there are only two developers, me and the chief of staff of Zuo Quan.

However, when it comes to the thinking of this discipline, in fact, thousands of years ago, our ancients already had this awareness.

Have you ever thought about it, Tian Ji raced horses, and under the condition that the three horses corresponding to Lu were not as good as King Qi, he just reversed the order of appearance and won the victory.

Liu Yuan watched everyone finally put their minds on listening to the lecture, and continued, let's call this method of reversing the order of appearance to win for the time being game theory, so have you ever thought about it, if we are on the battlefield, can we use game theory to win!

Liu Yuan's words made everyone have to think deeply, especially many boys carefully recorded the case in their notebooks, for fear of missing a word. "I see! It turns out that this is game theory, and this young principal is much stronger than that chief of staff. Outside the window, Rapel said excitedly. Rapel, don't be intoxicated first, hurry up and tell us what is Tianji horse racing, we don't know what consciousness is. Michelle said anxiously.

But before he could do it, Liu Yuan had already continued, "During the Spring and Autumn Period and the Warring States Period, there was a military strategist in China named Sun Wu, who had such an idea in his Sun Tzu's Art of War, that is, to strategize and win a decisive victory thousands of miles away. This is also the meaning of the naming of our discipline. "Sun Wu is the one?" Barbara pushes Pulla, only to find that the guy is completely immersed in the class.

In Wuhan in winter, it is rare to have a snowfall, and in the blink of an eye, the entire world world is dyed white.

Several German students were padding their feet in the wind and snow, their hands were red from the cold, but they still insisted on recording the content of the lectures in the room.

When the bell rang for the end of class, Liu Yuan asked the students to take a break, picked up the tea by himself, and drank two sips, only to find that it was already snowy outside, and the snowflakes were rolling in the cold wind and wanted to run into the house.

Zhao Yiman hurriedly closed the window and gave Liu Yuan a pleading look. In fact, those German students didn't, and Liu Yuan also saw it, but Liu Yuan was still a little hesitant.

A few Chinese students ran out of the city to deliver hot water, and the German students just said thank you, drank the water, and then complained again to the discussion.

The young man Liu Yuan, who even had a lapel, knew him, and many instructors praised him, saying that he was very smart and hardworking. "Label, can you tell me what made you insist on learning this subject in the cold storm and snow, you must know that this is only an emerging subject." Liu Yuan asked.

Germany is just an emerging country, it is not as vast as China, nor does it have a vast colony like Britain, so how to make rational use of resources is very important to us in Germany in the future war. Rapel bowed respectfully to Liu Yuan.

Germany will definitely become strong with soldiers like you, go to the classroom and listen to the lectures, you are also my students. "Really, thank you so much." Several German students hurriedly bowed to Liu Yuan and walked into the classroom excitedly.

The students were already very familiar with these tall, blue-glassed Germans, and many of them even had a good relationship, so as soon as they walked into the classroom, some students gave way to them.

At this time, the second class began, and it was impossible for Liu Yuan to continue to talk about those simple examples, but to start doing simple deepening.

In the naval war between England and Spain, there were seventy transports in one battle, and a large number of supplies had to be transported to seventy different ports, and each ship took a different amount of time to go to each port.

Liu Yuan saw the eager Zangke family and asked, "Do you want to try our great poet?" Liu Yuan called the Zangke family, but the young man talked for a long time, but he didn't say why.

Liu Yuan didn't continue to waste time and called up Rapel. "Teacher, it is impossible for you to calculate this question by enumeration, because he is at least 70 times 60...... Multiplying by 1 possibility, that is, the factorial of 70, is too large a number to be enumerated by all human beings. This can't be calculated at all, and at this time, two immature voices interrupted Rapel, "Who said that there is no way to calculate, if there is detailed data, as long as I give me twenty minutes, I can solve it, and I can help the British win this war." ”

At this time, Liu Yuan realized that it was two seventeen or eighteen-year-old little guys who were talking, and the two of them were discussing too seriously and forgetting everyone in the classroom.

Liu Yuan did not interrupt them, but looked at the two people in front of him with happy eyes, who said that there is no genius in China, aren't these two in front of you!

Maybe he couldn't get used to seeing two people disrupting the order of the class, and finally someone stood up to stop him, "Chern Shiingshen, Hua Luogeng, have you two played!" ”
