Wandering Spaceship in Deep Space Chapter 27: Big…Big guy?

　　 Zhang Yuan observed the other person’s expression. If the other person is the kind of person who "I am very powerful, and the world is invincible", 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 person 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 quickly.

　　 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, 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 probably more than 70% of the data will be discarded."

　　 "Yes."

　　 Ye Kaifu nodded again.

　　 Zhang Yuan continued: "I think these redundant data should not be discarded. One hand and the arm have 22 joints, and only 22 points of data are taken. It is indeed not too big. Wrong. 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."

　　"The first method 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... …"

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

　　 Ye Kaifu was ecstatic at first, repeatedly calling out "reasonable."

　　 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 max[i][j] is, what are you doing?

　　 But a breath from a strong man made him wonder how to speak.

When 　　 opened his mouth, he 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 these 5 degrees of freedom are missing , It looks like an excavator. You don’t seem to think about it..."

　　 Ye Kaifu understood this sentence. He also knew this common sense. He had been pondering it for a long time, but in the end he had to give up strategically because of the difficulty.

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

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

　　 Zhang Yuan said: "The calculation of rotation can usually be done with quaternions. Among the books of this type, the better one is "Quaternion Physics", which can be understood with a little foundation of complex analysis. Up."

　　 just said that, and 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: "...If his previous teammate was him, maybe he would get the first prize, right?"

　　 "The main thing is that my undergraduate school is not very good, and there are so few geniuses who can compare 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 by studying hard, I will definitely be able to surpass him, Ye Kaifu!"

　　 He couldn’t wait to say: “Zhang Yuan, I’ll invite you to a supper, I didn’t understand it just now, can you say it again?”

　　 "I still eat now, it's almost 11 o'clock, 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 I have to eat, the nightlife has just begun!"

　　 "Then... OK."

　　 If the blood sugar level is too low, the brain will be 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 of human life. Students generally don’t sleep until 12 o’clock.

　　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, my country's Flying Dragon is also good, an authentic Sky Mothership equipped with the latest electromagnetic guns."

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

　　 After barely understanding what he was talking about, Zhang Yuan licked his dry lips: "However, the current research speed of these weapons is not fast, right? The trend in the whole world is cooperation, not confrontation like before. , So the research on various weapons has also slowed down."

　　 Ye Kaifu spit wildly, as if it hadn’t been like this 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 kind of driving force is more than a thousand light-years away? If it is on Alpha Centauri, then it is driving force!"

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

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

　　 Seeing that Ye Kaifu fell into a frenzy and chattering on his own, Zhang Yuan suddenly said something and interrupted him: "Brother, if you do this, you won’t have a girlfriend!"

　　 "Why?!"

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

　　 Zhang Yuan surreptitiously looked around, and found that the blond female reporter who had been bullied by him was not at ~IndoMTL.com~ Then he breathed a sigh of relief and swaggered into a chair.

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

　　"Is this name not cute?"

　　 Zhang Yuan felt a little funny, "Yes, it's cute! But girls probably won't 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.

　　 is no big deal. In this age, 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: "Isn't it true that those who are still staying on campus are mostly high school students? It's great to be young, I really miss my college time."

　　Zhang Yuan said: "It should be mostly academic bullies, but not all of them. There are also many paddling guys who 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 capitalized."

　　 was said that, Ye Kaifu recalled his experience of licking a dog, he was used by that "ex-girlfriend".

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

　　 is so stupid!

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

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