Deep Space Fleet

Zhang Yuan observed the expression on the other side. If the other person is a kind of "Lao Tzu is invincible, the world is invincible", then a few words will be enough.

I do n’t have a deep friendship anyway, there is no need to quarrel with each other to make you die.

But if the other party really wants to ask, it is good to exchange a few words with each other.

"Nothing to mind, let's just say it!" Ye Kaifu hurriedly said.

Zhang Yuan continued: "... This whole function should be used to handle the pressure change of the glove? That is the SDK interface of that leather glove."

"Yes!" Ye Kaifu's heart jumped, but he didn't expect this kid to really understand.

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

"Yes."

Kui Ye Kaifu nodded again.

Zhang Yuan continued: "I don't think that all of this redundant data should be discarded. There are 22 joints in one hand and the arm, and only 22 points of data are taken, but there will not be much error. But Without the rest of the details, there will be a rough feeling ... "

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

"The first type is to calculate the variance of the data after the data is divided. The variance of the redundant data will not be very large ... As long as this calculation is performed, it can be judged whether it is redundant data. Anyway, it is better than throwing it away randomly ..."

"The second type is after the data is partitioned, we can use a value function to calculate the value of the partitioned data ... suppose max [i] [j] here represents the maximum value from the i-th data to the j-th data. Excellent solution, the dynamic transfer equation is max [i] [j] = max (max [i] [k] + max [k + 1] [j] + w (i, j)) ... "

Ye Ye Kaifu began to hear a flutter of excitement, shouting "justified".

He was silent from beginning to end, so that he was 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 the strong made him wonder what to say.

As soon as I spoke, I became illiterate.

"... In the end I want to say that although there are only 22 joints in one arm, there are at least 27 degrees of freedom, because the arms, wrists and fingers can be rotated. If these 5 degrees of freedom are missing, operate It's like an excavator. You don't seem to think about it ... "

开 Ye Kaifu understood this sentence. He also knew this common sense and thought about it for a long time at the time, but eventually gave up strategically because of the difficulty.

一旦 Once the arm can rotate, the modeling difficulty and design difficulty will inevitably increase exponentially, and he has no way to handle it.

"What do you say should be adjusted?"

Zhang Yuan said: "The calculation of rotation can usually be done with quaternions. In this type of book, the better is" quaternion physics ", which can be understood with a little complex analysis.

I just said that, he felt his thoughts gradually became clear.

It really is good to be a teacher.

"A quaternion ..." Ye Kaifu knew the term and was already convinced.

He was thinking wildly: "... If his previous teammate was him, maybe he won the first prize?"

主要 "The main thing is that my undergraduate school is not very good. I have too few geniuses to compare with me, so that there is a kind of laziness. But it's different now ..."

Soon, he started to encourage himself again: "Work hard, fighting! Only by studying hard, Ye Kaifu can definitely surpass him!"

He couldn't wait to say, "Zhang Yuan, I'll invite you for supper. I didn't understand it just now, can I repeat it?"

"I still eat 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 he felt a little moved.

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

"Then ... OK."

If your blood sugar level is too low, your head will be mentally retarded.

Zhang Zhang comforted himself like this.

Heart is not as good as action, the two slipped out of the bedroom again.

I have to say that university seems to be the most energetic period in human life. Before 12 o'clock, students generally don't sleep.

Dongdongmen is still lively.

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

"... I really like the Enterprise developed by the Eagle Country, and the Giant Rock Turtle in the Rice Country is also good. Well, the Chinese Flying Dragon is also good. The authentic Sky Mothership is equipped with the latest electromagnetic gun."

确实 "Indeed, these space weapons ... are shocking results."

After barely understanding what he was saying, Zhang Yuan licked his dry lips: "However, the current research speed of these weapons is not fast? The whole world's trend is cooperation, not confrontation like before, so each Research on weapons has also slowed down. "

Ye Ye Kaifu spit and flew, as if it hadn't been so long for a long time: "There are aliens, isn't that Dyson ball the driving force! Although it is more than a thousand light years away from us."

"What is the driving force for more than a thousand light-years? If it is Alpha Centaur, it is a driving force!"

如果 "If the era of the big star sky really starts, maybe everyone can buy a private spacecraft?"

"... There must be that day, I already think about it, my spaceship is called Queen Elizabeth! I can fly my spaceship to space travel!"

I watched Ye Kaifu fall into a frenzy and chattered on his own, Zhang Yuan burst out coldly and interrupted him: "Brother, you won't have a girlfriend!"

"Why ?!"

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

Zhang Yuan looked around sneakily, and found that the blonde female reporter who had been bullied by herself was not at ~ www.readwn.com ~, and was relieved, sitting in a chair with a big swing.

因为 "Because you keep saying something like Elizabeth or something in front of me. From this term, I've judged that you don't have a girlfriend ..."

"Isn't this name cute?"

Zhang Yuan felt a little funny, "Yes, very cute! But girls should not like it."

"Together!"

"Together!"

"Together!"

Suddenly, the table next door was noisy. This group of people drank a lot of wine, and a couple even kissed together in the noise.

It's not a big deal for me. In this era, this behavior is normal.

Facing this kind of dog abuse behavior, Zhang Yuan glanced twice before looking too lazy.

Kai Yefu sighed and said with a little envy: "The ones who are still on the campus are basically Xueba? You are so young, you really miss the time in college."

Zhang Yuan said: "It should be the majority of learners, but not all. There are many paddling goods that want to hold their thighs and win a prize."

"Anyway, there is a national award, whether it is applying for a scholarship or looking for a job, it is more capital."

I was told this way, Ye Kaifu recalled his experience as a dog licker, and he was used by that "ex-girlfriend".

Well, it ’s called "ex-girlfriend". Actually, I did n’t even hold my hand. I just gave it a name and wanted to be hooked.

I'm so stupid!

Sunda said bitterly: "The hardest thing in college is not to watch lovers show affection, high school show, local money show money, but to watch couples show banknotes, high school show love, high money show ..."

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