Li Mu's words pulled back those financial students who were still in surprise.

It's just that it's just a shift from one surprise to another.

How long has this been?

Less than half an hour?

And then there's a way?

Is this really fake?

To be honest, if Xu Canyao hadn't said those words to them just now, they would have thought that Li Mu was bragging.

You must know that all the math cows they called before thought for at least an hour, including Xu Canyao, who also thought for an hour, only pushed a few steps back, and then froze again.

As a result, Li Mu's words suddenly surprised them all.

At this time, Li Mu, who raised his head, also noticed Xu Canyao, and couldn't help but be surprised: "Hey, Senior Xu, are you also there?" ”

Xu Canyao waved his hand again and again: "Big Brother Li, I don't dare to be your senior." ”

He pointed at Zhang Weilong: "I met him by playing basketball, and he asked me to help a few days ago, but I didn't expect them to know you, I wondered what else I was asked to do, you alone is not enough." ”

Li Mu scratched his head: "I just came." ”

Xu Canyao was stunned, Li Mu just came?

He really didn't ask Li Mu when he came just now, so he wasn't as shocked as Zhang Weilong and the others, "How long have you been here?" ”

"Like...... Half an hour, right? ”

Xu Canyao: "......"

So he was also shocked.

He thought about it for two days!

Then I thought of the key point and couldn't think of it, so I ran over and asked Lin Yao again......

Autistic.

Bitter in my heart.

Li Mu didn't expect that he would accidentally blow people down, so he turned to Zhang Weilong and said, "I thought of a new model, which should be able to solve your problem." ”

"I'll write it to you briefly."

With that, he walked over to the blackboard, picked up the chalk, and began modeling.

He writes very quickly, because the computer has strengthened his control over his body, and the board is still fine.

It's just that for the graduate students of the Department of Finance present, no matter how good-looking the board books are, they can't stop their heads from being enough!

They didn't have the i3-530 in their heads, and when they saw Li Mu's modeling, they immediately began to overload and shut down.

What is this about......

They can understand every number symbol or something, how to combine it to become a book of heaven?

Thinking of Li Mu's words, write them briefly?

What do you call it simple?

At this time, they finally understood a truth, don't despise any math boss, otherwise he will use terrible math to give you a headache.

And Yun Rongshang was also stunned, it turned out that this was when Li Mu was in full swing?

The questions she asked before seemed to be really ......

It's not interesting.

As for the only one who can barely keep up with Li Mu, it is only Xu Canyao.

This problem is not pure mathematics, nor does it have high requirements for mathematics like mathematical physics, so Xu Canyao can still understand it.

In his heart at this time, he was holding the last bit of competition, wanting to see which was better between Li Mu's method and his own method.

After all, Li Mucai thought about it for less than half an hour, and he thought about it for two days, and Professor Lin Yao helped with this BUFF.

Li Mucai thought about it for a while, there will always be gaps, right?

People are not computers......

However, after seeing a few steps ahead of Li Mu, he changed his mind.

Forget it, anyway, Li Mu is already powerful, as long as his method can be on par with Li Mu.

As a result, after looking at a few more steps, he lowered his requirements again, just a little worse than Li Mu, after all, he is a genius!

It would be nice to see how much worse he is from this genius when the time comes.

Until the end -

Don't look at it! Open to the pendulum!

He collapsed directly into the chair next to him, giving up thinking.

Is there really a limit to this person's IQ?

In this way, the entire blackboard was filled with Li Mu's writing.

Stop the chalk, clap your hands, and look back.

The first quarter is the derivation process, which is densely written, and the last quarter is the finished model.

Not......

It shouldn't be a big problem, get it.

Then he turned his head to Zhang Weilong and said, "Okay, that's pretty much it." ”

"You can use this model directly, although I can't understand your topic, but according to your requirements, as well as these data, I estimate that this model should be what you want."

"After that, you can find a few examples to substitute in and try again."

With that, he moved out of the way.

Zhang Weilong swallowed his saliva and walked up.

He couldn't read the first three-quarters, so he used the final model.

Although this model also looks very tall, it is just ......

In this way, after looking at it for a while, he finally understood the model.

Of course, it's only about seeing how to use it.

Subsequently, he used this model to substitute several new data, and finally was surprised to find that the results obtained were very consistent with the actual situation.

The errors are all within the confidence intervals.

Zhang Weilong touched his face, took another half step back, completely incorporated the entire blackboard into his field of vision, and looked at it again.

My heart was full of disbelief.

That's ...... Solved?

This stumped that they had a problem of almost a few weeks, so it was directly solved?

So suddenly......

He turned his head to look at Li Mu over there.

At this time, Li Mu had already returned to his seat and closed the computer.

Apparently, he is confident in this model.

Zhang Weilong's heart was completely convinced.

Who said in the future that studying physics could not solve their financial problems, he directly slapped him.

Fart!

Isn't there one now?

In the same way, whoever said that to solve the mathematical problems of finance, it is necessary to understand the meaning of the problem, he also slapped it.

Li Mu didn't say that he would directly sort it out for them, and even what level of modeling he gave, Zhang Weilong was a little unclear.

It can only be said that even if this modeling is placed in the paper of the Journal of Finance, the top journal of finance, he probably will not feel abrupt.

I will probably sigh in my heart, I really deserve to be a cattle person who can publish top magazines, and I am admired and admired for being able to make such a model.

At this time, another person next to him came up and asked, "Senior Brother Zhang, this model ...... How's it going? I'm a little uh...... I don't understand. ”

Zhang Weilong is not only their senior brother, but his mathematical ability is also recognized as the best under their mentor, so he can always understand it, right?

Zhang Weilong came back to his senses, a little surprised.

Who made him not fully understandable?

Of course, this is not for outsiders.

He turned around, looked at the rest of the research group, met their expectant eyes, and then said with a smile: "If there are no other questions, I think we all have to thank Li Mu." ”

"This problem, solved!"

Hearing this, the discussion room immediately erupted in cheers.
