Chapter 92: Successfully Solving the NP-Complete Problem and Receiving System Rewards! (Part 3/3)”

“When do you plan to stay here until?” Tang Feng continued to ask.

“I want to finish reading these magazines before leaving.”

Tang Feng immediately felt a headache coming on.

With so many magazines, finishing them all would take at least two to three hours.

They might not even finish before the library closed.

“Let’s just go!” Seeing his expression, Su Xiaoli stood up.

“How about this? You continue reading the magazines, and I’ll work on some problems,” Tang Feng decided after a moment’s thought.

“Work on what problems?” Su Xiaoli was puzzled.

“Math problems! Aren’t there still many world-class math problems? I might as well use this time to solve one of them,” Tang Feng answered.

“Do you really need to be so dramatic? A world-class math problem, and you think you can solve it in such a short time?” Su Xiaoli could hardly believe her ears.

“Let’s try! Anyway, we won’t know if it’s possible unless we try,” Tang Feng said with a slight smile.

“Which world-class math problem are you planning to solve?” Su Xiaoli asked, quite curious.

Just as Tang Feng was about to answer, the voice of the system suddenly echoed in his mind.

“The system has issued a new mission. Solve an NP-complete problem within three hours. Completing the mission will reward you with ten thousand points!”

Upon hearing the mission’s details, Tang Feng’s brows furrowed.

The NP-complete problem was arguably the foremost among these world-class math challenges.

Since this math problem was proposed, countless mathematicians had attempted to solve it, only to return empty-handed.

Some mathematicians even used supercomputers for massive verification efforts but could only verify a small part of it.

No one had truly solved this math challenge.

Tang Feng initially intended to tackle a somewhat simpler math problem.

After all, with only three hours, completing a mission with a high difficulty level was certainly impossible.

But he hadn’t expected the system to issue such a challenging mission at this moment!

It was as if the system did not want him to earn those ten thousand points!

“Tang Feng, are you okay? Why aren’t you speaking?” Su Xiaoli, noticing his distracted state, became anxious.

“I’m fine,” Tang Feng shook his head, saying, “I plan to tackle the NP-complete problem.”

“What? The NP-complete problem? I feel like I don’t understand a single word,” Su Xiaoli’s face was filled with question marks.

“How to explain… Let’s say someone tells you that the number 13717421 can be written as the product of two smaller numbers, you might not know whether to believe him. But if he tells you that this number can be decomposed into 3607 times 3803, then you can quickly verify that his answer is correct. In other words, all complete polynomial nondeterministic problems can be transformed into a type of logical operation problem known as satisfiability problems,” Tang Feng tried to simplify the explanation.

Su Xiaoli was even more confused after hearing this.

To her, Tang Feng’s explanation felt like listening to a book of mysteries.

She understood each word and knew what it meant. But once combined into sentences, she was lost.

“Alright! I’ll start preparing! You keep reading,” Tang Feng stood up and left.

When he returned to Su Xiaoli with a stack of draft paper, he began to focus on solving this world-class math problem.

Time ticked away.

Tang Feng’s writing flew across the page!

One sheet of draft paper after another was quickly filled with his writing.

To save time, Tang Feng skipped a lot of steps.

Otherwise, even if he exhausted himself, he couldn’t complete the system’s mission in such a short time.

Su Xiaoli occasionally looked at him.

At this moment, Tang Feng was completely engrossed in his work.

Regardless of what happened around him, it seemed unrelated to him.

Finally, Tang Feng completed the proof of the NP-complete problem just before the three-hour deadline.

He felt extremely exhausted!

Even though his body had been strengthened several times, the high intensity of mental exertion still overwhelmed him.

“Congratulations to the host for completing the system’s mission! Ten thousand points have been credited to your account, please check,” the system announced.

After hearing this, Tang Feng’s hanging heart was finally at ease.

Then, he laid his head down on the desk and fell asleep.
