RBCT Chapter 408 The Temptation Of One Credit!
Chapter 408 The Temptation Of One Credit!
The laptop fan started spinning, and dozens of computers in the entire classroom were spinning!
On everyone's computer, the city starts to be generated at the same time!
Song He stared nervously at the city extending to all directions, praying crazily in his heart that it must not exceed 400 intersections!
One hundred, two hundred, three hundred, four hundred!
The expanding city has quickly exceeded the 400th intersection, and has no tendency to slow down at all, and continues to expand!
"What a living father!" He cursed quietly.
Five hundred, five hundred and fifty, six hundred, six hundred and fifty!
In the end, the number of intersections was fixed at 666!
Song He's face turned pale, he was afraid of whatever he wanted!
There was a gasp in the classroom. The candidates were deeply shocked by the difficulty of the test questions. The huge scale of the city scared everyone. The computers brought by some students were too old and jammed into PPT on the spot!
On the stage, An Yulong's skinny goat face was expressionless, his eyes scanned the whole class sharply, and he spoke:
"This class will only take the first 20 students who took the exam, and the rest will lose their qualifications to take the class!"
"If you get a score of 90 or above in the course opening exam, you can be selected into an elite small class and take extra classes at night!"
"How to judge the score? The full score is 100 minus the comprehensive congestion rate. If you can reduce the comprehensive congestion rate to less than 10%, it will be more than 90%!"
"At the same time, the first place in this exam can directly get 1 credit!"
"You should have read the school regulations. The mandatory requirement for undergraduate graduation is 100 credits! Seize the opportunity yourself!"
After An Yulong finished speaking, the atmosphere in the class suddenly changed!
Although the questions are rarely abnormal, you still have to bite the bullet!
No one wants to be kicked out of the course they finally signed up for. If luck strikes, it would be very tempting to get a credit!
The keyboard and mouse sounded in unison, and the candidates were busy operating.
With a simple click, you can manually modify the road. What everyone does is to make changes while thinking, check the real-time congestion situation, and confirm that their thinking direction is correct.
Song He did not hold the mouse, but just tapped the keyboard and moved his perspective to observe the entire city.
Those candidates around who are busy clicking their mouse to change paths are not opponents at all, they are all rookies!
Just like playing chess, experienced chess players will have an overview of the overall situation and first grasp the macro trend of the entire chess board. Only a novice would focus on one or two chess pieces and impatiently move the chess pieces to attack. This is reckless behavior!
In five minutes, Song He memorized the city's building and road information!
A Y-shaped river divides the entire city into three large parts, connected to each other by several bridges.
The urban construction is quite messy, with industrial areas, residential areas, tourist areas, and commercial streets intertwined, and the traffic conditions are naturally unbearable to look at!
Almost every street is blocked, with traffic jams all the way from the east of the city to the west. The whole city is basically in a state of traffic paralysis!
[Comprehensive congestion rate: 91%! 】
Song He sighed deeply, feeling like a doctor looking at a patient's case and discovering hundreds of diseases from head to toe. It is simply a miracle of life that such a patient can survive.
Let’s separate and treat the most serious diseases first.
He took his hands off the keyboard and did quick mental calculations.
We already have experience in mathematical modeling of 400 intersections. We only need to modify some parameters according to local conditions to apply it to this city.
Five minutes later, after the mental arithmetic was completed, Song He put his hands on the keyboard and started typing, typing in mathematical modeling.
Soon, hundreds of lines of mathematical model input were completed, press Enter!
The computer fan spins faster, and the program runs, reading the newly input mathematical model and automatically modifying the roads in the city.
Where roads need to be widened, where ramps need to be installed, and where elevated roads need to be added, all are explained in the model!
Large-scale changes in roads change the flow of cars with them.
In the lower right corner of the screen, the numbers start to jump:
[Comprehensive congestion rate: 88%! 】
[Comprehensive congestion rate: 72%! 】
[Comprehensive congestion rate: 60%! 】
The data was finally fixed at 60%, which means that based on the current mathematical model, Song He could only score 40 points!
My palms are sweaty!
He was convinced that this mathematical model was enough to score more than 80 points in a city with 400 intersections, but when applied to a city with 666 intersections, the score was actually cut in half?
Press one hand to type on the keyboard, move the perspective, and observe the modified city.
Song He's face was tense and his mind was overloaded.
The field of view captures dozens of vehicles at the same time and observes the route of each vehicle.
It has to be said that this program is developed very realistically, and the status of each car is completely different.
Some cars have clear goals and are experienced drivers who are steady and smooth, overtaking and changing lanes, and reaching their destination through the optimal route.
Some cars seemed to be lost, passing through a complicated fork repeatedly, circling between several blocks like a headless fly, and it took four turns to find the correct exit for the fork.
Some cars are purely accident-causing machines, causing collisions as soon as they drive out of an intersection, killing one or two passers-by from time to time, and causing several congestions along the way.
"In 1997, I learned to drive a car, uphill and downhill, and crushed more than a thousand people..." Song He hummed an ancient ditty in a low voice.
Finished browsing the whole city.
He took his hands off the keyboard and placed them on the table.
Keep doing the mental math!
In the past, Song He always thought that theoretical and cutting-edge mathematics was the most difficult, after all, it was very abstract to think about.
But now he realized that he was wrong, very wrong. The city in front of him was detailed and specific. He could even see the movement of each car in real time, but it was extremely difficult to calculate!
My brain aches and I have to endure the pain to fight!
He picked up the inspiration from the mental arithmetic in the cafeteria and continued to calculate.
First, use the brain cell algorithm, assuming that the vehicles in each block only connect nearby blocks and will not cross the city. At the same time, the traffic flow in each area has a generally fixed flow direction.
After calculating, Song He's brow suddenly jumped.
What if it were a little more abstract?
Suppose there is an idea in the brain that needs to be transmitted from the left side of the brain to the right side.
No single brain cell can grow synapses across the brain, but there are a series of brain cells that release neurotransmitters in a relay, transmitting thoughts through synapses.
Corresponding to the urban scenario, suppose there is an express delivery that needs to be transported from East City to West City.
So according to the pattern of brain cells, there is a car moving back and forth on each street, constantly transporting goods from one intersection to another, and one car continues to relay...
My thoughts suddenly opened up and Song He was inspired!
He began to further abstract the mathematical model, trying to eliminate the differences between the brain tissue model and the road network model as much as possible, and tried to unify the two models using highly summarized mathematical language!
It's difficult, but only by doing this can you hope to get high scores!
Take a deep breath and get to work!
