I Became a Genius Engineer

Angry Cheolwoo Lee (2)

“aaa! Annoying!”

I’m annoyed and angry to death. I didn’t think much about Chinese fakes until I experienced it.

But, isn’t this too much?

To take what I made with so much effort so easily?

They didn’t stop there, they were even trying to sell it as their own product by changing the shell a little bit.

Even in China, isn’t this a bit beyond commercial morality?

“Why are you like that? What’s going on?”

Changsoo next to him said.

“No… that’s…”

should i say this? Should I not? It seems that it was hacked.

Even though I’ve seen Changsoo for a long time, I still don’t trust him to that extent.

I don’t know if it’s Minseok.

“If there is.”

“Uh. What is it?”

“What if that DT company modified my CAK a bit and resold it as their own?”

“Hmm? Is it possible to sell it as your own? It’s not like you passed on the source.”

“It’s just decompiling and changing the appearance a little bit, along with the name.”

It seems that the source code was not passed over, but the appearance could be changed as much as you like.

“Hmm… if you do that, it’s three dogs. Just illegal use isn’t enough, so you sell it as if it’s yours?”

“huh.”

“It’s a complete asshole. But it’s not just once or twice.”

“okay?”

“No, that’s right. Our domestic companies have entered China a lot in the past. But what’s going on now? We’ve been robbed of our technology by the Chinese, and we’ve all been blown away.”

“Oh, I think I’ve seen it on the news a few times.”

“Why? They say that?”

“No, I wonder what would happen if that happened.”

“Eh, I’m sure I’ll do that.”

“I wish it were.”

“why?”

“Oh, no.”

While talking with Changsoo, the door to the club room opened.

“Who are you at this late hour?”

“Yeah~ Cheolwoohi! There was Changsoo too.”

“Oh, what’s up late?”

“I have some work to do.”

“Minseok-ah, you’re having a lot of trouble because of me. Aren’t you working until late?”

“hahahahaha, no. I’m not struggling because of you, I’m trying to do it myself. Don’t be too burdened.

Somehow, Minseok seemed to be getting more reliable.

“Oh, Minseok has grown up.”

Chang also seems to agree.

“hahahaha, no. More than that, what were you guys doing?”

“Well, I just studied. Ah, the time is already like this. I have to go soon.”

“Are you going already?”

“It’s already, it’s 9 o’clock. I have to go home.”

“hahahaha, yes. Go in~”

“See you tomorrow!”

Changsu packed his things and went to the club room.

“Minseok, I have something to tell you.”

“What is it? Have you had another accident?”

“No, what an accident.”

“say it.”

“……. I hacked DITSA.”

“……? what?”

“China’s DTS. It’s in the navigation business, and it’s preparing to do a call taxi business.”

“No, I know the company. But? You hacked it?”

Minseok was very aware of various companies and industry trends these days. It seems that he went around looking for an investment place and listened to it a lot here and there.

“Uh. These guys are using my CAK without permission!”

“……. No, no matter how hacked it is.

“Uh, how would I have made the TSS when I was a soldier.”

“Well, it’s really great. No, being great isn’t the problem. No, what if you hack it? It’s an accident! It’s an accident!”

Minseok said as if he was worried.

“Really, I was just trying to see if I was using it illegally or not. But, they didn’t end there. It’s not just changing the shell of the CAK, I’ll explain it while watching.”

He showed Minseok the data obtained through hacking and explained it.

“……You really stole these documents?”

Minseok looked at me with a confused expression and said.

“uh.”

“Crazy, it’s really amazing to see it in person. It’s really a devil’s talent.”

“Well, I was lucky.”

“But what if you get caught?

“Don’t worry about that. I’m not caught in the military security system.”

Hacking incident while in the military. If I hadn’t been honest, I could have carried it to the grave.

“It’s cool, it’s dope. If you can’t track in the military, should you say you can’t actually do it?”

“Isn’t that right? No place is as sensitive to cyberattacks as the military.”

“Anyway, it’s great. But to use that talent for something like that.”

“No, what’s wrong. Thanks to you, we knew they were trying to steal our CAK.”

“That’s right. Those bastards.”

“I’m angry and annoyed, what can I do?”

I asked Changsoo, but he said he couldn’t find anything sharp. What is different about Minseok?

“It’s a way…. I’ll look for it, but I don’t think it’ll be easy. I’m not going to terrorize the server.”

Terror to the server?

Oh, sounds like a good idea… … . Well, no. Anyway, if you restore the server and improve the vulnerability, it’s over.

Couldn’t do much damage.

“That’s right, that doesn’t hurt much.”

“What are you really trying to do?”

“no no.”

“Huh, I’m already worried. Let’s talk about the blue light, I don’t think we can do anything about it.”

“Is there a way to say blue light?”

“Well… wouldn’t it be better to know than not to know?”

“How do you explain? Trying to steal the CAK? That I hacked into it is a secret only to you.”

“Yes.”

“We have to work it out ourselves.”

“Hmm… I’ll think about it for a moment. Is there any good method?”

Minseok was silent for a long time.

After a while, Minseok opened his mouth again.

“No way.

“under…….”

“This is unfair, but I have to move on. CAK has many other vendors.”

“No. I can’t go on like this.”

“Then what are you going to do?”

“I don’t know yet.”

“… just don’t make an accident.”

“I don’t know. I could have a big accident at this rate.”

“Please… you’re doing well enough as it is.”

“don’t worry.”

“Oh hey, that’s right Lee Chul-woo! It’s not something that can be stopped. Yes, do it yourself! I’m responsible for the rest.”

“Oh, it’s reliable. But don’t worry too much.”

“Yes, yes. I’m not worried. So, do you have any plans?”

“No, I’ll think about it from now on.”

“hahahaha, yes. Then I’ll have to do some work too.”

“Suffering.”

Minseok went to fill out the paperwork again, and I sat down in front of the computer again.

‘Ha, how should these guys cook? Is there any better way?’

Then it suddenly dawned on me.

‘Ah, did you say that they have a C* algorithm or something of their own technology?’

I connected to the DT server again and found information about the technology.

「C* Algorithms」

I was able to find the relevant documentation right away, and started looking closely.

‘Oh, you made it better than I thought? It seems to perform better than DFS and BFS, and it finds things with higher complexity faster than Dijkstra’s algorithm.’

It seemed to be a slightly modified version of the A* algorithm, a pathfinding algorithm.

‘Because I have this level of skill, I get invested like that.’

I didn’t think it was a tech company for nothing.

‘Shall we test it?’

I immediately started testing by implementing C* algorithms, DFS, BFS, and A* algorithms.

First at complexity 1,000.

「A*: 1.13s, Accuracy: 97」

「DFS: 0.93s, Accuracy: 92」

「BFS: 1.23s, Accuracy: 99」

「C*: 1.03s, Accuracy: 96」

The DFS algorithm showed slightly faster speed. C* algorithms did not perform as well as expected.

Accuracy was all the same.

Next at complexity 10,000.

「A*: 2.31s, Accuracy: 88」

「DFS: 2.83s, Accuracy: 92」

「BFS: 3.92s, Accuracy: 99」

「C*: 1.53s, Accuracy: 92」

As the complexity increases by about 10 times, the performance of the C* algorithm is noticeably improved. Next, the A* algorithm, which is the matrix of the C* algorithm.

Accuracy was also observed.

‘The higher the complexity, the better the performance. Accuracy is also respected.’

great? Did you develop your own algorithm like this? I should imitate

‘Hmm, wait a minute, but I think it would be better if I modified it like this?’

After looking at each algorithm, I came up with a better method.

I just started writing a new algorithm.

‘If you do this, I think it will be very fast and more accurate than other algorithms. Shall we test it?’

The test was conducted first at complexity 1,000.

「A*: 1.13s, Accuracy: 97」

「DFS: 0.93s, Accuracy: 92」

「BFS: 1.23s, Accuracy: 99」

「C*: 1.03s, Accuracy: 96」

「test: 0.83s, accuracy: 100」

‘Hey, look, it’s really fast if you do it this way. Let’s try it even at 10,000.’

「A*: 2.31s, Accuracy: 88」

「DFS: 2.83s, Accuracy: 92」

「BFS: 3.92s, Accuracy: 99」

「C*: 1.53s, Accuracy: 92」

「test: 0.93s, accuracy: 100」

‘Wow, can this be okay? Almost no speed difference? Accuracy is still 100?’

great? Didn’t you make something bigger than you thought?

As I delved deeper into C* algorithms, my revenge was behind me.

‘Oh, it’s not like this now. I have to take revenge on these guys.’

Then I suddenly remembered.

‘I’m sorry, Minseok. I’ll buy it and hit it once.’

After apologizing to Minseok in my heart, I logged on to TopCode, a famous overseas coding site.

TopCode. Algorithms under research were also uploaded, and it was also a place to rank programming skills by solving problems.

There were rumors that all those with high scores here worked for American military companies, global IT conglomerates, or NASA.

It was so famous and reliable.

I turned on a translator on the site and started writing something in poor English.

「About the new pathfinding algorithm C*」

What if the C* algorithm, which they developed independently and with great care, was made public and used by people all over the world?

‘Then you should know a bit about copyright, right?’

An eye for an eye for an eye!

No less, no more, just pay back what you got.

“complete.”

The C* algorithm created by DT was uploaded to the TopCode site.

“Huh…. Let’s taste it. Dogs.”

“Huh? What did you say?”

“Huh? You haven’t gone yet? I thought you did.”

“There’s a lot to do. What did you just say?”

“I’m sorry, Minseok. I had an accident.”

“Huh? What accident?”

“They developed their own C* algorithm and released it to the world.”

Upon hearing this, Minseok was silent for a moment.

“……? What? Did I just not hear you?”

Minseok is confused.

“No, I heard it right. I’ll pay you back just as much as I received. I’ve revealed their skills.”

“No…if you reveal that.”

“Why? Don’t they use my CAK as they please? I should let them use their skills as they please.”

“No matter what… do you have the confidence not to get caught?”

“I just told you. Our military couldn’t find me either. Can you find me on the TopCode site? I uploaded it anonymously.”

Minseok pondered for a while before saying.

“Ha ha ha ha! Yes ha ha ha ha! Lee Cheol-woo, who else would do this if it wasn’t you! Yes, well done. Take a taste of those bastards. Enjoy what you spilled already!”
