"What I have built here is an unbalanced countable Markov chain, so the Markov chain can form a directed graph..."

The dialogue between Maldo and Du Xiaodi went straight to the topic from the beginning. Maldo was indeed very interested in the algorithm proposed by Du Xiaodi in his paper. He had read it through many times before coming to China and repeatedly deduced some of the calculation steps. At this time, he came to Du Xiaodi with his own questions, and it is conceivable how difficult it is to make an academic master like Maldo wonder.

Du Xiaodi answered a few words and found that it could not be explained in words. On the one hand, this is because her English proficiency is still very limited, and on the other hand, this kind of thing involving mathematical derivation cannot be explained clearly. After obtaining Yu Feng's consent, Du Xiaodi picked up a piece of chalk and began to write formulas for Maldo on the blackboard. Maldo was sitting down at first and couldn't help it after a while. He also got up and walked to the blackboard, picked up another piece of chalk, and wrote it in a simplified manner, while writing.

Du Xiaodi was a little nervous at first, afraid that she would mess it up. After a while, she gradually entered the state and forgot her fear. Although Feng Xiaochen taught her this algorithm, she had deduced it countless times and modified it with the results of computer calculations. It can be said that she is familiar with it. How could Maldo's problem be difficult for her? Previously, she had spent several days and nights trying to find the analytical solutions to this set of equations. Although this work was not completed in the end, she had studied all kinds of changes in the equations. If Maldo writes any formula, she can deduce it immediately, without even a single bump in the middle.

The two of them wrote while saying that after they had a blackboard filled, they wiped it clean and continued writing. Maldo is the kind of person who forgets everything as soon as they entered the work state. How could they remember that he was invited to be an examiner? He only regarded the conversation with Du Xiaodi as a fellow traveler. Du Xiaodi had no choice but to follow Maldo's rhythm and didn't bother to see the attitudes of Yu Feng, Cai Xingquan and others.

Everyone in the audience was stunned. Those who were familiar with Cai Xingquan and Yang Zhuoran naturally knew what the old and young were saying on the podium. Others, including Yu Feng, were not professional in welding, were stunned after hearing a few words. They only watched the formulas swaying in front of their eyes, looking very profound.

Gao Lei sat down, with his lips slightly raised, treating everything on the podium as a play. He firmly believed that Maldo was the actor invited by Cai Xingquan. The things Maldo and Du Xiaodi wrote on the blackboard seemed mysterious, but in fact they were all arranged in advance, just to block Gao Lei's mouth.

How could such a coincidence happen? Where can there be such an expert who is disrespectful to you? If you ask a random question, you can argue with a student for so long? Is it because the student's level is too high or your level is too low?

“good,verd!”

After writing the blackboard for more than a dozen times, Maldo smiled on his face. He slapped his face and expressed his appreciation for Du Xiaodi in an extremely exaggerated tone.

"Du, you are very outstanding. Your understanding of welding theory is extremely inconsistent with your age. I think that at least a scholar over 35 years old should have such attainments. Also, I think you are a mathematical genius and your thinking is very good!"

Maldo said to Du Xiaodi from the bottom of his heart. Cai Xingquan asked him to give Du Xiaodi a good comment, and he agreed, and prepared that if Du Xiaodi's performance was not too bad, he would just say a few good words, which would be considered as giving Cai Xingquan a face. But now, the praise he said came from the heart, because he felt that it was really amazing that a girl in her 20s could do this level.

Hearing Maldo's praise, Yang Zhuoran and Li Zhaohui slapped gently and expressed their agreement. They are knowledgeable and can see what kind of skills Du Xiaodi has shown just now. It can be said that the questions raised by Maldo are more difficult than the most difficult questions they prepared in advance, but Du Xiaodi answered these questions satisfactorily. Some of them are Du Xiaodi's own opinions, which make them, the old people who have been immersed in the welding field for many years, feel refreshed.

"Professor Yang, General Engineer Li, you two should ask some questions, too."

Seeing Maldo return to his position, Yu Feng said to Yang Zhuoran and Li Zhaohui.

Yang Zhuoran looked at Li Zhaohui, who smiled at him and shook his head. Yang Zhuoran also smiled and said to Yu Feng: "Principal Yu, the subsequent assessment is no longer necessary. Xiao Du's performance just now is enough to prove that she is an excellent welding student. I can say that it is rare in China to be able to reach her level."

"I think her level is enough to pursue a doctorate degree." After hearing what Li Zhaohui translated to him, Maldo echoed loudly.

"Is that true? I am an amateur when it comes to welding. Since all the three experts have said this... Professor Gao, do you think you have any opinions?" Yu Feng turned his head to Gao Lei and asked.

Gao Lei smiled slightly and said, "Is this procedure a little wrong? Mr. Maldo was invited by Professor Cai. From beginning to end, he was the only one who asked Du Xiaodi questions, and it seemed that there was only one question. Although they wrote many formulas on the blackboard, he thought that Xiao Du's level had reached the standard based on his words. Isn't this a bit rash?"

Yang Zhuoran said: "Professor Gao, the question that Professor Maldo just discussed with Xiao Du is a very difficult question. Xiao Du gave a satisfactory answer in the process. I think this is enough to prove her skills. To be honest, the questions prepared by General Manager Li and I are not as difficult as Professor Maldo's just now. Asking those basic questions is a waste of time."

Gao Lei said: "You two are electric welding experts hired by the Ministry of Machinery. I believe your level. But Professor Maldo, I am frank, who can prove that he knows welding?"

"What did you say? You said Professor Maldo doesn't understand welding?" Yang Zhuoran looked at Gao Lei, his face filled with surprise.

Gao Lei smiled and said, "I just raised a question. Professor Cai didn't say he is a welding expert, right? Maybe he is just an expert in other fields. It may not be appropriate to identify whether a welding graduate student is qualified, right?"

Maldo felt from the eyes of everyone that Gao Lei was talking about him. He asked Du Xiaodi, who was walking down from the podium and standing in front of them, "Miss Du, can you tell me what that gentleman was just talking about?"

Du Xiaodi thought about it and said in English: "Professor Maldo, this gentleman wants to know, do you know welding?"

"Is that?" Maldo nodded, and then said to Gao Lei: "Sir, I can tell you that in terms of welding, I am indeed just a new starter, and I don't know many problems."

Gao Lei also knows English. When he heard Maldo's words, his expression on his face became even more proud. He said, "Professor Yang, look, he admitted it himself, saying that he is just an entry-level person."

Yang Zhuoran showed a laughing and crying expression and said, "What's so strange about this? I also think I'm just an introductory person. In fact, scientific researchers have this feeling. The more they come into contact, the less they know. Professor Maldo said this."

"Are you sure? How do you know that he knows welding?" Gao Lei asked.

Li Zhaohui couldn't help it and turned to Gao Lei and said, "Professor Gao, you have a specialty in your profession. You are engaged in economics and don't know about our welding field. Professor Maldo is a well-known field in our field. In fact, Professor Cai has introduced it just now. He said that Professor Maldo is the executive member of the IIW. Don't you think the executive member of the International Welding Society does not understand welding, right?"

"International Welding Society..." Gao Lei's face suddenly turned into purple. Damn Cai Xingquan, what did you say? I thought it was an international chess association. You said that this was the abbreviation of the International Welding Society. Do I have such a big mistake? Who can get into the position of executive committee in the society? He personally came out to endorse Du Xiaodi's level, even if no one is qualified to question him. The more he said at this time, the more he slapped the face, the more miserable it would be.

"So that's the case, uh, then it seems that I've misunderstood." Gao Lei said angrily.

Yu Feng didn't want to let Gao Lei go, and he asked: "Professor Gao, are you satisfied with today's assessment results?"

"Very good, I think this form is still very good." Gao Lei said with a tough bullet.

"Then, Du Xiaodi's level should be recognized, right?"

"I think, since the experts have said that, it should be good."

"Do you think we need to organize further assessments?"

"Uh, maybe it's not necessary..."

"Okay, then I'm so grateful to Professor Gao. Otherwise, let's end today's assessment activity. Professor Cai, the school office has arranged a small banquet, and you can go with Professor Maldo. By the way, call Xiao Du, too. I think she had a very harmonious communication with Professor Maldo just now." Yu Feng began to arrange it as if no one was around, leaving Gao Lei aside.

Cen Jianwei walked to Gao Lei and asked respectfully: "Professor Gao, see, do you have any other requirements for our investigation? For example, do you have to do some work from other aspects?"

"I think it's all there is to end." Gao Lei replied with a dark face. Of course, he could come up with other solutions, but according to the current situation, it would probably be no different if he used other methods. He just slapped him in the face.

Cen Jianwei nodded with a smile and said, "Okay, we will complete the investigation report as soon as possible. We will use a special section to thank Professor Gao for the guidance provided by us in the investigation."
