First of all, the most detailed on the entire network is not my headline party, you __Number List__ will know why after you read it. Here is one thing that the entire network has not explained in detail, how the calculation formula of the virus growth model is calculated.

When we first planned to plan a fission event, if there was enough time, I believe everyone would go to the Internet to collect some information about fission. If you want to know the underlying principles of fission, you want to see some successful fission case introductions. If you have thoroughly researched this topic and mastered enough knowledge and materials before starting the project, you can have a good idea of when the fission activity is carried out, and the expected effect of the fission activity will also have a spectrum in mind.

Yes, me too. If you have collected some information, I believe you have also seen terms and explanations such as K value, fission level, virus growth model calculation formula, ROI, etc.

Maybe you, like me, are still a little confused. How many should these values reach? Why is this formula used to calculate the total number of users participating in fission activities. Why is the denominator K-1 and why the numerator is (K^t/ct+1)-1.

I found the original book, and the original book did not explain this formula. I searched all the articles I could find, and none of them explained this formula. They were all retellings of the original author.

Even the meaning of Cust(t) is different from what other authors write in the book. Generally speaking, people tend to believe what is in the book, but what is in the book is wrong!

I didn't feel comfortable if I didn't understand it. I asked 6 friends who had higher scores in the college entrance examination than me and had studied mathematics in college. This actually requires the use of mathematical knowledge **of summation of proportional series! **It seems that everyone has forgotten their high school knowledge after work, but don't be afraid, I will explain the derivation process in detail, and make sure you don't get confused after reading it.
