Recently, Qiao Jingyang has been busy with the collection of samples and the design of gene chips, and various companies and hospitals have been running around and going through approval procedures everywhere.

In Jingrun Gene, most of the bioinformatics analysis only needs to use the existing software to make good use of the data at hand to solve the biological problems that you want to solve. The company's bioinformatics analysis has a complete set of processes, and now the existing bioinformatics analysts have been able to meet their company's business needs, and Ye Chen and Xue Zhu are mainly responsible for the R&D center, which is to ensure that the software used for this process is updated and optimized, and even further, their tasks also include doing scientific research to publish articles in the name of the company, which is also part of the company's strength, and even an extremely important part of determining the company's future development potential.

Jiang Rou also started a part-time job in Jingrun Gene in addition to classes, 3 days a week, weekends and 3 weeks without classes. The training she received in the company made her progress rapidly, and their department did not look like a company at all, but like a scientific research institution.

Wednesday, 4 p.m., is the time for the R&D center's group meeting.

Ye Chen stood in front of his desk, fiddling with the projector, Jiang Rou took his computer and opened the PPT that Ye Chen posted in the group.

Hey, this week's topic is PAML

PAML is a software package that uses maximum likelihood to perform phylogenetic analysis of DNA or protein sequences.

Jiang Rou looked at Xue Zhu and Wang Jiaran next to her, and saw that they were all looking calm when they looked at the PPT.

Am I the only one who finds it difficult?

Jiang Rou took a sip of the water cup to hide her embarrassment.

The first few times I listened to the group meeting, Jiang Rou couldn't keep up, and when she went back at night, she had to check the information and chew it again.

When she talked during the day, she had a lot of questions, and she didn't dare to ask questions to delay everyone's time. Because she's the only one who doesn't know.

Hey, when will you become a great god?

Come on, come on

The weather has begun to warm up, the sun is shining outside, and a magnolia tree has bloomed in the yard. A faint scent wafted from the window.

Jiang Rou looked out the window lazily, there will be some breeze blowing in,

It's a nice day

Suddenly, Ye Chen's voice reached Jiang Rou's ears,

Jiang Rou turned her head to see that Ye Chen was standing in front of the projector, and his PPT was displayed on the screen behind him.

Coming soon?

Jiang Rou walked around, only to see Xue Zhu put away his usual hanging, turned on the computer and seemed to be about to take notes, Wang Jiaran leaned on the chair with his hands and looked ahead seriously.

Ye Chen smiled in front, "Then let's start."

After speaking, he turned off the lights in the office, and Jiang Rou, who was next to the window, also had the foresight to close the curtains.

The indoor lights suddenly dimmed,

Ye Chen clasped his hands together and put them on his chest, "Okay, then let's start." ”

He was wearing a shirt and trousers, his bones were beautiful, and he had gold-rimmed glasses on the bridge of his nose.

Jiang Rou looked at Ye Chen with little stars on her face, what a perfect boyfriend!

After the finished, Jiang Rou took out the voice recorder, and she will definitely go back to make up for the class tonight.

Ye Chen was in front of the projector, carefully explaining the principles and algorithms of PAML to everyone, his voice changed from high to low, like the clear spring in the mountains flowing slowly.

The sound is very good, but I know all the words, how can I not understand them when they are strung together?

Jiang Rou listened and hurriedly checked the information,

"In PAML, the process of calculating the maximum likelihood method consists of the following two steps: calculating the likelihood value of a single locus, calculating the likelihood value of the phylogenetic tree, and ......"

After an hour, I finally finished speaking

Jiang Rou exhaled a breath of turbid air and leaned back on the work chair.

That's a lot of dry goods

After Xue Zhu and Wang Jiaran listened, they both took their cups to fetch water to drink, and only Jiang Rou was still sitting on the chair and thinking about the question just now.

Xue Zhu rummaged through the snack box, he was still quite hungry now, it was 5 o'clock. He took out a bag of biscuits and threw them to Wang Jiaran next to him, "Do you eat them?"

Wang Jiaran smiled, "Eat",

Wang Jiaran tore open the package and put a cookie in his mouth.

I looked down and saw that the salted egg yolk tasted okay.

Wang Jiaran ate biscuits, leaned on the table, and secretly looked at Jiang Rou with his spare eyes,

I saw Ye Chen go over to answer questions to Jiang Rou, who was scratching her ears and cheeks, and the two were intimate

Wang Jiaran squinted, he walked to the snack box and flipped it up,

What gummies, chips, hash browns, egg yolk crisps, nougat......

Wang Jiaran chose two packs of sandwich biscuits, stood up and shouted at Ye Chen, "Senior Brother Ye, your snacks." ”

Hearing the scream, Ye Chen turned his head, and just wanted to say no, only to see Wang Jiaran's biscuits smashed at him. Fortunately, he was quick to see and move, otherwise he would have hit his head directly.

Seeing this, Wang Jiaran exclaimed, "Brother Chen, are you okay?" ”

Ye Chen waved his hand, "It's okay"

It's just a pack of cookies

Wang Jiaran smiled, "I'll pay attention to it in the future."

After speaking, he gently threw a bag of biscuits to Jiang Rou, "Jiang Rou, yours." ”

Jiang Rou shook her head, "I'm not hungry yet."

Six o'clock, after work.

The street lights were already on, the lights of the surrounding buildings were flickering, and the sky was a dull blue.

In the evening, a few people ate together and walked leisurely along the street.

Led by Ye Chen, the R&D center will have a group meeting once a week, and everyone will take turns to talk about PPT.

Generally, it is to talk about a high-scoring article, do a good PPT, and explain the algorithm behind the software like a report, as well as the mathematical principles. Sometimes Qiao Jingyang will come to tell them about the forefront of the industry and the latest research directions.

The company is very prosperous nearby, next to a century-old famous school like K University and the city center, there are people coming and going on the street, and the traffic is like a note.

There are quite a few restaurants nearby, and now it's a place to eat.

But this excitement did not infect Jiang Rou at all.

Every time after the group meeting, Jiang Rou looked sullen.

She was anxious about her own food, her basic knowledge was not solid, and it was difficult to listen to those things.

Ye Chen took Jiang Rou's hand, and the two walked alone in a row.

Looking at Jiang Rou's frowning appearance, a smile appeared in the corner of Ye Chen's eyes, "What are you thinking?"

Jiang Rou raised her eyes and looked at Ye Chen, she asked the doubts she had been asking for a long time, "Do you have to learn mathematics?"

In the past few months in the company, Jiang Rou has gained a lot, she has mastered the principles of a lot of software, and the mathematical level is also making rapid progress, and the algorithms and principles of some classic software Jiang Rou can already write them silently with her eyes closed.

But the mathematical knowledge behind it, she is also really big.

When Ye Chen heard this, his eyebrows unconsciously raised, "Are you afraid?"

"It's easy to copy the code and change the code, but if you want to make a product that accurately meets your needs, you must have a deep understanding of the mathematical principles behind each algorithm, which is very helpful for us to adjust the algorithm parameters and improve the algorithm model in the later stage. ”

Jiang Rou sighed, "I don't want to be a master of copy-paste flow either."

I'm just under too much pressure, Jiang Rou sighed in her heart.

Ye Chen touched her head, "What do you think?" "You've made rapid progress. ”

Every industry will be graded, and programmers are no exception, the better ones are called engineers, the worse ones are called code farmers, and the worse ones are called code animals.

Nowadays, most of the technology is open source, few people will study the technology, or secondary development, and many programmers are masters of copy-and-paste streams.

But to be a good engineer, mathematics, algorithms, logic, very important.

Xue Zhu, who was in front of him, heard their conversation and said to Jiang Rou with a smile, "Jiang Rou, don't be afraid. With Brother Chen here, you definitely won't fall into the copy-paste stream. ”

After speaking, Xue Zhu also patted Qiao Jingyang's shoulder, "Senior Brother Qiao, did you say?"

Qiao Jingyang glanced at Xue Zhu, "Looking for a beating, who is the connotation?"

Xue Zhu didn't care, and continued to say with a grin, "As the industry says, those who play algorithms are called engineers, and they rely on blue bars to work hard, like mages.

Math is equal to the maximum value of the blue bar, poor math, low mana, and soon reach a bottleneck. Foreign languages affect the speed of returning to blue. Experience and intelligence acceleration and penetration.

If you don't play the algorithm, you are called a code farmer, like a warrior, who fights hard by blood bar, physique plus life, spirit plus life recovery, and experience acceleration. Jiang Rou, it depends on what you want to be. ”

Jiang Rou paused for a moment, is there still such a statement?

"Then it's still a mage. Fei Lan is better than Fei Hong."

Wang Jiaran also smiled, "You don't want to hate it if you haven't learned much." ”

"I'm not, I don't. ”

"It's here, it's here. Let's go eat."
