Chapter 563 Brother Master, Don’T Talk Too Much
Song He sat in front of the computer, typing away.
Brain-inspired programming was running on the computer screen, and countless undulating mountains appeared in the darkness, layer upon layer, composed of hundreds of thousands of yellow dots.
His idea is simple and crude, build an electronic sandbox!
Use brain-inspired programming to simulate a desert environment, then use brain-inspired programming to simulate targets and drone swarms, and repeatedly modify the program for testing!
"Damn it, are you working on an electronic sandbox?" Xie Yuanxun was standing beside him at some point, his tone was horrified.
"Didn't you say you were going to challenge me? What's the point of peeking at my work process?" Song He turned around in shock.
"I came over to look at the data paper. When I turned around, I couldn't help but glance at it and saw that you were making electronic sand dunes." Xie Yuanxun raised his hand and knocked on the data paper on the wall to explain, "You can also look at mine."
"Then...look at yours!"
Xie Yuanxun turned his laptop around and pointed it at Song He.
Song He glanced quickly and was surprised again, "Build a large model of the trajectory directly? Are you so fierce?"
"What the heck, I'm going too far. I've just started building and I can't continue. Why don't I have to re-read the data sheet to find inspiration." Xie Yuanxun smiled bitterly, "I'm going to copy your ideas, too. Build an electronic sandbox to simulate it.”
Song He nodded calmly and continued working.
He didn't panic at all.
It doesn’t matter if the general direction is copied, the key to achieving results lies in the details!
Just like World War II aircraft carriers and today's aircraft carriers are both called aircraft carriers, bicycles and luxury sports cars are both called cars, and the first grade of elementary school and the first grade of a doctoral degree are both called first grade, the electronic sand table and the electronic sand table will be completely different!
How to simulate the distribution of sand dunes, how to simulate wind, and how to simulate a swarm of drones, each step requires a large amount of mathematical theory. Inextricable details affect everything, and the slightest mistake will lead to huge mistakes!
The sound of mouse and keyboard echoed in the dormitory, and the two of them worked hard, each weaving an electronic sandbox on the screen.
Xie Yuanxun seemed to be unable to sit still. From time to time he got up and ran to the wall, looking around at the data paper. After facing the wall for a moment, his expression suddenly dawned. He returned to the computer and started tapping for a while. After tapping for a while, he couldn't sit still again, and the cycle continued.
Song He, on the other hand, was sitting steadily and still, more stable than an old monk meditating. He only had manual movements all over his body, and the keyboard and mouse frequency was very fast, and the computer fan also kept ringing heartily.
The next day, it was five o'clock in the morning.
Breakfast was placed on the table, including steamed buns and porridge. The two of them ate in a hurry, making eye contact as they ate.
"Look at yours?" Xie Yuanxun said.
"Look at yours." Song He said.
The two moved their chairs to sit together, then turned their respective laptops around to compare them.
The gap is ridiculously large!
Xie Yuanxun's electronic sand table is beginning to take shape. Many sand dunes expand or shrink with the wind, and the drone maneuvers and hovers in the air. However, the whole picture has a dull air, the changes in the dunes are lifeless, and the drone's movements are like a shadow puppet show. , obviously a semi-finished product.
Song He's electronic sand table actually looks like an ink painting. The dense sand dunes flow smoothly, and every trace of wind is clearly visible. The drone group is flying automatically under the guidance of AI, and its movements are agile like a flock of birds. .
"What the hell? Why is your sand table so silky?" Xie Yuanxun was dumbfounded.
"My ideas mainly refer to topology. The total amount of sand dunes is fixed, and the wind is an external force that will knead the sand dunes into various shapes." Song He smiled, "Unfortunately, topology is my strong point!"
"I want to change my challenge. Let's win two out of three games." Xie Yuanxun struggled for a moment and couldn't resist the temptation. "You win this time by building an electronic sandbox. Can you make a copy for me?" "
"Easy to say."
Song He was very happy and immediately sent him the data package of the electronic sandbox.
"After the sandbox is finished, the next step is to build a large mathematical model of the drone swarm. With the mathematical model summarizing the behavior pattern, we can write the operating program." Song He said, "Brother Xie, how about this second round?"
"Okay!" Xie Yuanxun was full of fighting spirit, "I won't fail a second time! I will win this game! You are an expert in artificial brain programming, and I have nothing to say if you lose. As for building mathematical models, I I am not humble enough to call myself a master!"
"Brother Gaoshou, don't talk too much." Song He smiled.
"If you don't dare to say harsh words, why the hell do you call him a master?" Xie Yuanxun was arrogant and unruly.
After eating, the two continued to work.
Xie Yuanxun was very excited at first. He was so surprised by the brand-new electronic sandbox. He kept flying drones and modifying environmental parameters, and played with great interest for a long time.
But the excitement wore off after an hour, and he began to yawn profusely. In order to catch up on the electronic sandbox last night, he only slept for four hours and was seriously lacking in energy.
Song He was as calm as ever. Although he slept less, he was not sleepy at all. He was sitting in front of the computer as steady as a rock. His whole person was completely absorbed in the mathematical model, with countless formulas and mathematical inferences rolling through his mind:
"According to Reynolds decomposition, the laws of instantaneous vector and instantaneous scalar of velocity satisfy..."
"First decompose the flow variables of the equation into the sum of the average quantity and the pulsation quantity, take the time average and perform Reynolds decomposition..."
"Consider the transient incompressible continuity equation and N-S equation in the three-dimensional Cartesian coordinate system..."
As I wrote, sweat gradually formed on my head, and my body began to cool down my overheated brain.
It has to be said that if dozens of drones are to be used to maximize their effectiveness in a complex and ever-changing desert battlefield environment, the calculations required are ridiculously complex!
A strong wind will change the power and trajectory of multiple drones, causing a chain reaction to the entire drone group's reconnaissance circle, which must be restored.
The situation of individual drones being shot down must also be considered. Stupid reconnaissance gaps cannot appear, and the operation of tearing down the east wall to repair the west wall must also be done.
The drone may not always be fully charged when it is released. On the battlefield, there will always be situations when it is released before the battery is fully charged. Different trajectories with different batteries must be made to ensure the maximum reconnaissance effect.
After adding various variables and details to off-site recycling, the complexity doubled!
Song He scratched his sweaty head and recalled the experience of the night he caught the spy.
He was sitting in the back seat of the car. Once the sunroof opened, he would fly out several drones against the wind and sand. After the power was exhausted, he could not get it back. He could only carefully calculate the number and save the remaining drones like cannonballs. Fight out.
The car moves very fast and turns frequently, drawing wild and disorderly ruts in the desert. Therefore, the off-site recovery trajectory of the drone needs to change all the time as the car moves.
This ever-changing feeling...is very much like a nonlinear partial differential equation.
Song He was typing on the keyboard, trying to write a unified mathematical model of drone swarms on the computer, revising and revising it, writing more and more, and unknowingly he wrote until dark.
But as the size of the model on the screen grew larger and larger, his face became increasingly ugly.
Too long!
This mathematical model is too bloated!
It’s just as long as it is, but the key is that the further you write, the more you feel that there are more variables that have not been taken into account, and the more inconsistencies there are, and for a while, you can’t even see the possibility of ending!
Even... I had a strong feeling that something was wrong!
"It's done!" Xie Yuanxun suddenly shouted.
