"Senior, this is my idea."

"Since the method you proposed to substitute the first derivative extreme value with the calculated first order derivative does not work, then change to a verification plan."

"What I think is that we divide the linear differential equation into four forms and perform operations separately. If all four forms are verified successfully, then we can prove the correctness and practicality of this simple solution."

"What four forms?" Wang Genji's eyes revealed curiosity.

Cheng Nuo stretched out his fingers and counted them one by one.

"The first type is the random differential equation of the constant coefficient blak-sholes: d=(udt+σdb)."

"The second type, the time-varying coefficient blak-sholes random differential equation: d=b(t)dt+σ(t)db."

"The third type is a random differential equation with a shape like dξt=(aξt+bξta)dt+ξtdbt."

“The fourth type,…”

After reading Wang Genji's paper last night, although he knew that there were obvious logical errors in Wang Genji's paper, it was difficult to say that the conjecture about the new solution was correct. However, Cheng Nuo could not resist his curiosity. Based on Wang Genji's paper, he spent the two morning classes of thinking and practice, and finally developed a seemingly feasible path.

Discuss the situation separately, then summarize the results and draw the final solution.

Cheng Nuo continued to explain his ideas to Wang Genji, "For example, in the first case, its corresponding pseudo-homogeneous differential equation dξt=σξtdbt, so ξt=eσbt, using constant variation, and then using the ito formula to find integrals,..."

Since Cheng Nuo does not have specific time to calculate step by step using formulas, he can only provide an idea.

As for whether this idea is correct or not, I'm sorry, Cheng Nuo cannot guarantee it either.

However, this is the most confident verification direction that Cheng Nuo can think of at present.

After the little episode of the cleaning lady, the two of them didn't stay here for long.

After Cheng Nuo told Wang Genji all his ideas, the two said goodbye here.

"Cheng Nuo, I'll try the idea you mentioned right now. If it's really feasible, then this paper can really be rescued." Wang Genji's face was already showing an impatient expression, his fists were clenched, and his expression was very excited.

The high fighting spirit has rekindled in my heart.

"Cheng Nuo, thank you this time. I'll treat you to a big meal later." Wang Genji's tone was sincere.

If Cheng Nuo hadn't helped, I'd probably not have discovered the errors in the paper if Wang Genji was given another week.

Not to mention...a brand new essay idea!

In Wang Genji's opinion, in order to understand his paper, Cheng Nuo probably almost didn't sleep all night last night.

Such a huge workload will take at least seven or eight hours to be enough!

These days, such an excellent good junior is rare!

Wang Genji was filled with emotion.

"No need, it's just a matter of raising hands." Cheng Nuo smiled and shrugged.

In order to relieve Wang Genji's guilt, Cheng Nuo specially added, "Besides, it doesn't take much time, just two classes of thinking and practice in the morning. Oh, no, to be precise, it's one and a half lessons."

Wang Genji: "..."

The gap! The gap!

I wrote this paper for more than five months before I finished it.

But Cheng Nuo is fine, just one and a half lessons are done.

Although he has his own paper as a reference, Wang Genji knows that except for the first third of the contents of his paper, the following parts are all wrong formulas with no reference value.

Can't compare, really can't compare...

Wang Genji finally understood why Professor Liao transferred Cheng Nuo, who had just entered the first year of college, to their research team.

Mathematical talent, this thing is not linearly related to age!

"Senior, what's wrong with you? Are you feeling uncomfortable?" Cheng Nuo looked a little unnatural when he saw Wang Genji's expression.

"It's okay." Before Wang Genji recovered from Cheng Nuo's words, he said in a daze, "Chen Nuo, I have to go back to the dormitory, so I left first.

"Well, goodbye to senior." Cheng Nuo smiled and waved.

…………

After finishing the matter, Cheng Nuo was relaxed.

Anyway, he has done everything he can do. And it depends entirely on him that Wang Genji can achieve.

"The sun in the east, the rain in the west! Brother, that sweetheart"

Cheng Nuo walked back to the dormitory with his hands in his pockets and hummed a little song.

Suddenly, Cheng Nuo's expression changed suddenly, while walking on the road.

He suddenly thought of something serious.

Wang Genji got a new idea for the paper. In the following period, he would definitely focus all his energy on writing the SCI paper.

But……

That guy Wang Genji is still in charge of the second part of the project!

Writing papers in class takes up almost all the time.

Where can Wang Genji take time to study the topic?

A paper can definitely be written without ten days or half a month.

The topic studied by Cheng Nuo and the others is already linked. Without the research results of the second part, Jiang Shuobo and Zhuang Poxiao cannot continue to study it even if they have great abilities!

What do I fuck...

It's a sin!

Cheng Nuo sighed to the sky, and tears flowed thousands of times in speechlessness.

He seemed to be watching the winter vacation and gradually moving away from him.

It's worth it! It's really worth it!

Cheng Nuo wished he could just slap himself now.

If he had known this, he would have been so confused about helping Wang Genji read the paper, find mistakes, and provide new solutions. What was the reason?

To dig a hole, then jump down by yourself?!

No, Cheng Nuo feels that he cannot let the tragedy happen!

The wonderful winter vacation should never be spent in research topics.

After returning to the dormitory, he chatted with Wang Genji directly on QQ.

Cheng Nuo: "Senior, are you here?"

It took a few minutes before Wang Genji replied.

Wang Genji: "Cheng Nuo, I just calculated the first form you mentioned. Sure enough, the final calculation result is exactly the same as the result obtained by using the constant change method."

"Hahaha, I knew that with my genius brain, how could it be wrong? The last time I had an error in verification, and this time I used the correct verification steps. I must prove the feasibility of this solution!"

Wang Genji seemed very excited.

Cheng Nuo: "That, senior, can I discuss something for you?"

Wang Genji: "What's the matter?"

Cheng Nuo: "Senior, are you busy revising your paper now? I think, the topic may take up too much time."

"So I think, senior, you will just hand over the task of the second part of the project to us three, so you don't have to worry about it. Just concentrate on writing the paper."

Wang Genji: "Cheng Nuo, who do you think of me Wang Genji as?!"???

Cheng Nuo was stunned for a moment.

I saw Wang Genji continue to type, "Transfer the second part of the work to you three, and then I will do nothing. When the project is completed, I will write my name. Get a free honor. Isn't this a waste of money?! Do you think I, Wang Genji, is such a person who doesn't want to force me?"

Cheng Nuo: "Senior, I just..."

Wang Genji: "Okay, Cheng Nuo, stop talking. Anyway, I absolutely cannot agree to this."

"Time is indeed a little tight, but at most it's just winter vacation. There wasn't a time when I couldn't go back. To be honest, I'm used to it, so don't worry about me, really."

What do I fuck...

Cheng Nuo almost vomited an old blood.

Brother, you are used to it.

But what about me?!

I'm still a newbie who has just entered college for less than a month!

Do you have to accept the cruel fact that you cannot go home during the winter vacation?
Chapter completed!
