Deep Space Planet Leader

Zhang Yuan observes the other person's expression. If the other person is the kind of person who "I'm so awesome, invincible in the whole world", then you can add a few sentences at will.

Anyway, there is no deep friendship, there is no need to quarrel with each other to the death.

But if the other party really wants to ask for advice, it’s good to exchange a few words with each other.

"Nothing to mind, just say it!" Ye Kaifu said hastily.

Zhang Yuan continued: "...this entire function should deal with glove pressure changes? That is the SDK interface of the leather glove."

"Yes!" Ye Kaifu's heart jumped, and he didn't expect this kid really understood.

"Because the amount of data generated by the entire glove is too large, this algorithm will selectively discard most of the data, and probably more than 70% of the data will be discarded."

"Yes."

Ye Kaifu nodded again.

Zhang Yuan continued: "I don’t think all these redundant data should be discarded. A hand and an arm have 22 joints and only take data from 22 points. There is a big mistake. But without the details of the other parts, there will be a very rough feeling..."

"I have several ideas to deal with these seemingly useless data."

"First is to calculate the variance of the data after the data is divided into blocks, the variance of the redundant data will not be very large... As long as it is calculated in this way, it can be judged whether it is redundant data, anyway, it is better than discarding it randomly..."

"Second is after the data is partitioned, we can use a value function to calculate the value of the partitioned data... Assuming that max[i][j] here means adding from the i-th data to The optimal solution for the j-th data, the dynamic transfer equation is max[i][j]=max(max[i][k]+max[k+1][j]+w(i,j))……"

Ye Kaifu at first heard ecstatically, repeatedly calling "reasonable".

Behind is silent from beginning to end, so that it is completely sluggish.

Because, in the end, he didn't know what Zhang Yuan was talking about...

This man, what is max[i][j], what are you doing?

But a breath from powerhouse made him wonder how to speak.

When I opened my mouth, I became illiterate.

"...The last thing I want to say is that although an arm has only 22 joints, it has at least 27 degrees of freedom, because the arm, wrist and fingers can be rotated. If this is missing With 5 degrees of freedom, it feels like an excavator. You don’t seem to think about it..."

Ye Kaifu understands this sentence. He also knows this common sense. I pondered for a long time, but in the end it was too difficult to give up strategically.

Once the arm can be rotated, the modeling difficulty and design difficulty will inevitably rise exponentially, and he has no way to handle it.

"Then how do you say it should be adjusted?"

Zhang Yuan said: "The calculation of rotation can usually be done with quaternions. In this type of book, it is better It is "Quaternion Physics", which can be understood with a little complex analysis basis."

With that said, he felt that his thinking had gradually become clearer.

Being a teacher is really good.

"Are you quaternion..." Ye Kaifu knew this term, and he was a little convinced in his heart.

He was thinking wildly in his mind: "...If his previous teammate was him, maybe he would get the first prize?"

"The main thing is, my undergraduate school is not very good. There are so few geniuses that can be compared with me, so that there is a kind of laziness. But now it is different..."

Soon, he started to encourage himself again: "Work hard, fighting! Only study hard, I, Ye Kaifu, will definitely be able to surpass him!"

He couldn't wait to say: "Zhang Yuan, let me ask you to have a supper. I just didn't understand how to understand it, can you say it again?"

"I still eat it now, it's almost 11 o'clock, and I will get fat."

Because he only ate half a bowl of noodles, Zhang Yuan did not feel full, and was a little moved.

"Of course you have to eat, the nightlife has just begun!"

"Well... OK."

If the blood sugar level is too low, the brain will Mentally retarded.

Zhang Yuan comforted himself like this.

The heart is not as good as the action, and the two sneak out of the dormitory again.

I have to say that college seems to be the most energetic period in human life. Students generally don’t sleep until 12 o’clock.

The East Gate is still very lively.

Along the way, Ye Kaifu kept talking about various mechanical models, various chip parameters, various latest space weapons, with an exaggerated and fanatical tone.

"...I like the Enterprise developed by Eagle Country very much, and the U.S. Giant Rock Kametai is also good. Well, China’s Wyvern is also good, authentic Sky Mothership, loaded with the latest electromagnetic Cannon."

"Indeed, these space weapons...very shocking results."

After barely understanding what he was saying, Zhang Yuan licked his hair shaft. Lips: "However, the current research speed of these weapons is not fast, right? The entire world's trend is cooperation, rather than confrontation as before, so the research on various weapons has also slowed down."

Ye Kaifu’s saliva splash across, it seems that it’s been a long time since I talked about the mountains like this: "There are aliens, isn’t that Dyson ball the driving force! Although it is more than a thousand light years away from us."

"More than a thousand What kind of driving force is a light year? If it is in Alpha Centauri, then it is a driving force!"

"If the era of the big starry sky is really started, maybe everyone can buy a private spaceship?"

"...There must be that day. I have already thought about it. My spaceship is called Queen Elizabeth! I can drive my spaceship to space travel!"

Ye Kaifu fell into a frenzy, each minding their own business chattering endlessly. Zhang Yuan suddenly said, interrupting him: "Old Brother, you won't have a girlfriend if you do this!"

"Why? !"

"How do you know?" Ye Kaifu sweated on his head and closed his mouth.

Zhang Yuan glanced around surreptitiously, and found that the blond female reporter who had been bullied by herself was not there. She was sighed in relief and sat swaggeringly on a chair.

"Because you are in front of me, you keep talking about Elizabeth and the like. From this noun, I can judge that you have no girlfriend..."

"Isn't this name Is it cute?"

Zhang Yuan felt a little funny, "Yes, very cute! But girls It shouldn't be like it."

"Together!"

"Together!"

"Together!"

Suddenly, the table next door became noisy. This group of people drank a lot of wine, and a couple even kissed each other in the chaos.

There is nothing at worst. In this era, this behavior is normal.

Faced with this dog abuse behavior, Zhang Yuan glanced at it and didn't bother to look at it.

Ye Kaifu sighed, and said with a little envious: "I still stay on campus now, basically all of them are high school students? It's great to be young, I really miss my college time."

Zhang Yuan said: "It should be the majority of students, but not all of them. There are also many paddling guys who want to hold their thighs and win a prize."

"Anyway, there is one. National awards, whether it’s applying for a scholarship or looking for a job, are more capital."

When he said that, Ye Kaifu recalled his experience of being a dog licking dog. "Used.

Well, I said it was a "ex-girlfriend". In fact, I didn't even hold my hand. I just gave it a name, and I wanted to take the bait.

So stupid!

He said bitterly: "The most bitter thing in college is not to watch couples show affection, learn to show their results, and local tyrants show banknotes, but to watch couples show banknotes, learn to show affection, and local tyrants show results. ......"

I really want to have a cute girl who really likes herself!
