202: Chapter 202 Four Lines Bloom, Deep Space Has to Grow Its Own Brain!

sentry ship arrival countdown: 98 days. Pangu Laboratory, Level B2, 8:20 AM.

Zhao Mingyuan dragged his swivel chair from his workstation to the master control console. Before he could even settle in, the laptop on his knees lit up.

"Su Che, I dismantled the autonomous decision-making architecture of the near-Earth version of the Xuannv last night. "

Zhao Mingyuan turned the laptop screen for Su Che to see; it was densely marked with red annotations.

"The problem is more serious than I imagined. The decision tree for the near-Earth version is a three-layer nesting. Task instructions are issued from the mothership, and the fighter jets execute them in a queue based on priority. "

"It works fine when communication is normal, but once communication is cut, the tree withers directly, and the fighter jets just circle in place waiting for instructions. "

Su Che scanned the annotations.

"How do you plan to fix it? "

"Not fix it, but cut it. Cut all three layers of the decision tree and replace them with a distributed Cognitive Graph. "

Zhao Mingyuan flipped to the last page of the annotations.

"Each Xuannv comes with a miniature tactical deduction engine. It doesn't rely on instructions from the mothership. It perceives the environment, judges threat levels, and decides whether to fight or run on its own. "

"Where will the computing power for the deduction engine come from? "

"The onboard distributed unit of the main god ai. " Zhao Mingyuan brought up a code framework.

"I created a lightweight branch of the main god ai's tactical deduction module and stuffed it into the Sub-nanometer chip to run. The computing power of a single Xuannv is about three-thousandths of the main god ai, enough for it to make its own judgments on the battlefield. "

Su Che looked at the framework without answering immediately.

Three-thousandths didn't sound like much, but the base computing power of the Sub-nanometer chip was significant.

Three-thousandths multiplied by that astronomical number was intelligence on a dimensional reduction strike level for any drone.

"What about the training data for the Cognitive Graph? "

"I plan to use the main god ai to run Monte Carlo simulations of deep space battlefields to generate one billion confrontation scenarios and feed them to the Cognitive Graph for a cold start. "

Zhao Mingyuan threw a goji berry into his mouth and chewed twice. "If a billion sets aren't enough, I'll add more. "

Su Che typed a few commands on the keyboard, allocating 20% of the main god ai's computing power pool to Zhao Mingyuan's workstation.

"Get to work. "

Zhao Mingyuan slid his chair back to his workstation, where the code editor on his laptop screen already had four windows open.

On the south side of the hall, Academician Zhang Weide sat in front of the Pangu Quantum Computer terminal.

He ignored the engineering calculator resting to the left of the keyboard and directly brought up the underlying flight control source code of the near-Earth version of the Xuannv on the supercomputing terminal.

Su Che walked over.

"Have you found the root cause of the cumulative deviation? "

Academician Zhang Weide flipped the source code to line 1700.

"Here, the attitude solution uses classical Euler angles, with a fixed three-axis rotation order. "

His index finger tapped the screen. "It's fine for short-distance maneuvering, but after more than three consecutive orbital changes, the gimbal lock zone eats up a portion of the angle information, and the deviation starts accumulating from there. "

"Switch to quaternions. "

"I did, but just changing the mathematical expression isn't enough. "

Academician Zhang Weide pulled a folded draft paper from his pocket and unfolded it. On it were three sets of coordinate transformation derivations.

"There is no atmospheric damping in the vacuum of deep space to provide natural correction. The drift rate of the attitude gyroscope must be compressed to within 0.001 degrees per hour. "

He caught his breath. "I need to add a real-time calibration loop for quantum inertial navigation to the flight control foundation, using data from space-based quantum star map navigation as an external reference. "

"Is the refresh frequency of star map navigation sufficient? "

"120 times per second, enough! I will finish the full-attitude solution framework for the quaternions today, and connect the star map calibration loop tomorrow. "

Su Che turned and walked toward the east side.

Academician Qian Zhenhua's workstation had three screens spread out, all filled with waveforms and topology structures of communication protocols.

"How far have you gotten with the underlying communication for swarm coordination? "

Academician Qian Zhenhua didn't look back, his pen tip pointing at a node on the middle screen.

"For the multiplexing rate of the quantum entanglement channel, the near-Earth version is one-to-eight. Eight Xuannv share one channel. The Solar System version needs to support hundreds online simultaneously. I have to increase the multiplexing rate to one-to-128. "

"Is 128 enough? "

"It's the limit. If I stack it any higher, the fidelity of the entangled state will drop below the threshold, rendering it useless. "

Academician Qian Zhenhua moved the pen tip to the edge of the topology map.

"So I changed my approach. Instead of stacking single-channel multiplexing rates, I switched to multi-channel hierarchical networking. "

"Every twelve Xuannv form a subnet. Within the subnet, it's one-to-twelve multiplexing, and between subnets, we use independent quantum relay links. "

"Three hundred Xuannv, twenty-five subnets, twenty-five relay links, all uniformly scheduled by the main god ai. "

"What about the synchronization latency between subnets? " Su Che asked.

"The theoretical value is at the nanosecond level, but it hasn't been tested yet. I have to wait for Zhao Mingyuan to define the communication interface for the Cognitive Graph before I can run the joint debugging. "

Su Che looked back at Zhao Mingyuan, who was switching rapidly between four code windows.

"Mingyuan, prioritize the communication interface definition. "

"Got it, this afternoon. " Zhao Mingyuan didn't even look up.

10:00 AM. Su Che got up and walked to the far west.

Wen Bo was not at his workstation.

The academician next to him pointed toward the corridor.

Su Che exited the Level B2 door and found Wen Bo at the corner of the corridor.

Wen Bo was squatting on the ground, a palm-sized dark gray thin sheet spread out in front of him, measuring the thickness with a vernier caliper.

"What is this? "

"A new substrate sample for the ultimate version of the stealth film. Zhou Dehai just cut it from the Zhulong Production Line at the Kaitian Base and sent it over on an express delivery. I've adjusted the composite ratio of carbon nanotubes and liquid metal three times; this is the third version. "

"What was wrong with the first two versions? "

"The first version had enough signal shielding, but the toughness was poor. It cracked after fifty deep space temperature cycles. The second version improved in toughness, but the shielding rate dropped by 8%. "

Wen Bo clamped the edge of the thin sheet with the caliper. "The third version changed the orientation angle of the carbon nanotubes by fifteen degrees. Theoretically, both indicators should meet the standard. "

"When will the test results be out? "

"Tomorrow at noon. Zhulong is running an accelerated thermal cycle test—five hundred temperature cycles. We'll have the data once it's done. "

Wen Bo stood up and tucked the vernier caliper into his belt.

"Su Che, you need to give me the interface specifications for the avionics integration. The stealth film isn't just pasted on; it needs to be jointly designed with the electromagnetic compatibility of the avionics system. I need to know the radiation characteristic spectrum of the avionics. "

"I'll give it to you this afternoon. "

Su Che turned back to Level B2.

All four lines were started, each gnawing on its own hard nut.

He sat back at the master control console and pulled the keyboard over.

The full blueprints for the Solar System version of the Xuannv were hanging on the right side of the main screen.

The things he had to do were more miscellaneous than any single sub-line; the cross-interfaces of all four lines were in his hands.

Zhao Mingyuan's decision architecture had to interface with Academician Qian Zhenhua's swarm coordination; Academician Zhang Weide's flight control had to be jointly debugged with Wen Bo's stealth avionics; Academician Sun Qiwen's power supply module had to meet the power consumption budget of all four lines simultaneously.

Five interfaces, five sets of adaptation logic, all written by him alone.

Su Che opened the code editor and created five blank project files.

His fingertips fell.

...

sentry ship arrival countdown: 97 days.

Someone in Level B2 must have turned up the air conditioning vent; the dry airflow made the A4 paper on the desk rustle.

Zhao Mingyuan's Monte Carlo simulation ran all night.

One billion sets of deep space confrontation scenarios were poured into the cold start framework of the Cognitive Graph, and 18% of the main god ai's computing power pool was eaten up.

"Cold start complete. " He straightened his back from the chair, his neck emitting two crisp cracks. "The communication interface definition is also out. Academician Qian, you can start the joint debugging on your side. "

Academician Qian Zhenhua poked half his body out from the pile of screens on the east side.

"Email the interface document to me. "

"Sent, twenty minutes ago. "

Academician Qian Zhenhua looked down and flipped through his email, found it, double-clicked to open it, and began checking the parameters line by line.

Academician Zhang Weide did not participate in this conversation.

He had been sitting in front of the Pangu Quantum Computer terminal for nearly thirty hours. The quaternion full-attitude solution framework was finished, and he was welding the calibration loop for the space-based quantum star map navigation into the flight control foundation line by line.

Academician Sun Qiwen walked over from the back row carrying an enamel mug and stopped next to Su Che.

"After tripling the power density of the scaled-down nuclear fusion power module, the heat dissipation wing area needs to increase by 40%. "

He placed a thermodynamic calculation table next to the keyboard.

"But in the flight control aerodynamic model from Academician Zhang Weide, the upper limit of the deployment angle for the heat dissipation wings is 35 degrees. A 40% area increment cannot be stuffed into the 35-degree deployment space. "

Su Che opened the calculation table.

"Change the heat dissipation wings to a foldable multi-segment type. They won't take up aerodynamic space in the stowed state, and the total area will be sufficient after deployment. "

"How do you handle the vibration of the folding mechanism during high-Mach flight? "

"Academician Zhang Weide. " Su Che called out. "Change the heat dissipation wings to a foldable multi-segment type. Add the vibration suppression to the flight control. "

Academician Zhang Weide stretched his head out from behind the supercomputing terminal.

"Give me the vibration frequency range. "

"Academician Sun will give it to you. "

Academician Sun Qiwen pushed the calculation table toward Academician Zhang Weide's workstation and squatted down next to the folding table with his mug.

Su Che continued to write interface adaptation code. Two and a half of the five project files were already filled; the remaining two and a half had to wait for the intermediate products of each line to come out before he could work on them.

Liu Huaqiang walked back from the communication area, flipping his notebook to a new page.

"Zhou Dehai reports that the accelerated thermal cycle test for the stealth substrate from the Zhulong Production Line has reached 350 cycles, and it hasn't cracked yet. "

Wen Bo, squatting in the corridor, heard this and poked his head in.

"Still 150 cycles to go. Don't be in such a hurry to pop the champagne. "

Liu Huaqiang ignored him and wrote a line in his notebook: Substrate Version 3, 350/500.

...

sentry ship arrival countdown: 96 days.

3:00 PM.

Academician Qian Zhenhua pushed the first version of the joint debugging results for the hierarchical networking protocol to the public big screen.

Twenty-five subnets, three hundred virtual Xuannv, all online simultaneously in the main god ai's simulated deep space battlefield.

Intra-subnet communication latency: Nanosecond level.

Inter-subnet relay latency: Microsecond level.

Three hundred units executing formation change instructions simultaneously; from reception to completion, total response time: 0.03 seconds.

Zhao Mingyuan poked his head over from the workstation side to take a look.

"0.03 seconds, three hundred units changing formation simultaneously. Even an eight-unit formation change for the near-Earth version takes 0.1 seconds. "

Academician Qian Zhenhua took off his pen cap and put it back on.

"Theoretical value. The actual test will have to wait until the full machine is built. "

Academician Zhang Weide stood up from the supercomputing terminal, took the draft paper out of his pocket, unfolded it, and walked to Su Che.

"The quaternion solution plus the star map calibration loop, full-condition simulation complete. One hundred consecutive orbital changes, cumulative attitude deviation: 0.0004 degrees. "

Su Che looked at the number.

The near-Earth version started drifting after three consecutive orbital changes, but the deviation of the Solar System version after one hundred orbital changes was thinner than a human hair.

"Finalized. "

Academician Zhang Weide folded the draft paper and turned back to his workstation.

Wen Bo turned in from the corridor, holding a dark gray thin sheet in his hand.

"Five hundred thermal cycles completed. No cracks, signal shielding rate 99.7%, toughness retention rate 96%. "

He slapped the thin sheet on Su Che's desk.

"The third version of the substrate is decided. Zhou Dehai can start production scheduling. "

Su Che picked up the thin sheet, flipped it over, and placed it back on the desk.

"Coordinate the Zhulong production scheduling through Dean Liu. "

Liu Huaqiang had already crossed out "350/500" in his notebook and changed it to "500/500, Passed. "

The progress bars for all four lines in Level B2 were pushing forward.

Su Che opened the five interface project files; the blank area of the third file could finally be worked on.

With Zhao Mingyuan's communication interface definition and Academician Qian Zhenhua's networking protocol in place, he could start writing the docking logic for the decision architecture and swarm coordination.

He pulled the keyboard over and typed the first line of code into the third project file.

Academician Li Zhengyang walked over from the weapon adaptation area, carrying a thermos cup.

He placed a report on the deep space beam drift modeling for high-order directed energy components on the corner of Su Che's desk.

"Draft of the drift compensation algorithm. It has been jointly debugged with the Quantum Radar locking data from Academician Qian, and the precision is sufficient. "

Su Che took the report and tucked it into the pending review folder.

Academician Chen Shian's documentation for the adaptive version of the microbial self-cleaning system also arrived, placed on top of the folder—two thin sheets of paper, clean and efficient.

Four main lines plus two auxiliary lines, six paths advancing simultaneously.

Su Che finished the first half of the third interface file, pushed the keyboard forward two centimeters, leaned back in his chair, and closed his eyes for ten seconds.

Ten seconds later, he opened them, pulled the keyboard back, and continued typing.

There were no windows outside.

Level B2 was underground, with no distinction between day and night.

But the countdown numbers in the corner of the main screen counted the days for everyone.

96 days.

The swarm's teeth were being ground out, one by one.
