When Mu Zi arrived at the company, some employees had already left from work, and there were still overtime employees left, who had ordered takeaway boxed lunches and were having a good time.
When everyone saw Mu Zi coming, they put down their lunch boxes to greet her.
"I have nothing to do, you guys eat." Mu Zi smiled and went straight to the president's office.
As usual, she checked the recent company statements, some contract information, and understood the operation situation.
By the time she finished reading these things, more than an hour had passed.
Wang Zhan asked her with concern, "Do you want to order something to eat?"
Mu Zi hadn't eaten dinner yet, she touched her stomach, she was indeed a little hungry, but now Bai Wei must have made dinner and waited for her to go home, so it would be too much of a let down to Bai Wei if she ordered a takeaway to eat.
"Go home." Mu Zi stretched her arms and stood up.
As she prepared to leave, she saw that the lights were still on in the technical department and couldn't help but wonder, "Aren't they all going home?"
Wang Zhan spat, "These tech geeks go back and play with their computers, how can the internet speed at home be as fast as the company? Of course all of them rely on not leaving, but also can save the electricity bill."
Mu Zi walked in and looked, the technician inside seems to be aware of, quickly switch the screen, the game screen instantly turned into a work interface!
Mu Zi couldn't help but smile and said, "Don't hide it, it's already off duty time, it's okay to amuse yourself."
It happened to be the technician who helped her check the courier order number last time.
"Good day president." The technician smiled sardonically.
Mu Zi walked over and saw a floor plan displayed on his computer and asked, "What is this? Also company business?"
"Yes, helping a rich woman catch a mistress." The technician's smile reveals a bit of urgency, "This business may seem insignificant, but it's actually very marketable, and is considered one of our company's main incomes."
Mu Zi was a bit curious, tilting her head to look closely at the floor plan - it should be an apartment, marked with floors and elevator locations, as well as some data she couldn't understand.
The technician explained to her, "This apartment has a total of thirty-two floors, we accessed the security footage at the entrance and in the elevator, and based on the time of the footage and the characters' walking routes, the computer algorithm deduced the destination, and found out what number of rooms the woman that this man is keeping lives in."
"So amazing?" Mu Zi was surprised.
The technician smiled smugly, "The power of technology."
Mu Zi thoughtfully asked him, "If there's no surveillance video, but there's a confession to provide the time and content, can you use the computer to act out the results?"
"Can ah, use cross validation!" The technician slapped his thigh and answered decisively.
Mu Zi raised her eyebrows, "Cross-validation?"
"Cross-validation is a statistical method." The technician was afraid that Mu Zi couldn't understand it, and used the most superficial method to give an example, "For example, the president saw me working overtime in the company, and Manager Wang was with the president, so we can conclude that Manager Wang can prove that I was working overtime in the company."
Mu Zi thought carefully and didn't say anything for a long time.
"You'll work overtime for a while tonight." She suddenly said.
The technician was confused and nodded his head blankly, "Hey, okay president."
Mu Zi returned to her office and logged into her net disk, which stored the information Jiang Chen had given her.
Not only was there a list of everyone on the yacht on the day of the murder, there were also statements from everyone, as well as drawings of the yacht's structure.
More than thirty people, the testimonies were true and false, even some guests said that they had been drinking, didn't remember, and weren't clear.
Want to sift out the real culprit from it, it is too difficult, but if there is such computer technology ... even if it can not lock the murderer, at least it can quickly sift out the suspects, right?
Mu Zi erased the names of the people, replaced each person s name with the English ABC, and then gave it to the technician to analyze.
The results came out quickly.
"Here, it's F." The technician pointed to the man's name and said, "He's the only one who could have been at the bow of the ship at 9:17 PM."
