Every blind date is a lottery. Unfortunately, the existing laws and regulations can only take away one sweetheart. How can we find the ideal object? It is too metaphysical to rely on fate. Fortunately, we have the mathematical tools discovered by mathematicians.
Now we just need you to answer one little question:
Of course I can't get your answer in the article, so suppose you can accept up to 20 blind dates. Now bring 20 into a magical love formula k=n/e, where n=20 and e=2.72 (natural number approximation). We can get k=7 (rounded), and this k is the number of objects you need to start looking for a girlfriend.
Because 1/e=0.37, k=n/e can be approximately equivalent to k = 0.37 * n. First, 37% of the total number (blind date) is used as the observation range of the experiment to predict the overall situation. Later, whoever is better than the forecast range (the top 37%) is selected.
Plato asked his teacher Socrates what is love? The teacher asked him to go to the wheat field first and pick the biggest and golden ears in the whole wheat field. You can only choose one period, and you can only go forward during the period, and you can't look back.
Plato did as the teacher said, and as a result, he walked out of the field empty-handed. The teacher asked him why he couldn't pick it.
He said: "Because you can only pick it once, you can't go back. Even if you see the biggest and golden one, don't pick it, because I don't know if there is a better one ahead. When I walked to the front, I found it was not as good as what I had seen before. The biggest golden ear of wheat has been missed. So I didn't pick anything! "
The teacher said: This is love.
Suppose we have n ears of wheat. We use this strategy to select the first K-ear wheat. Remember that the largest spike of wheat is marked as D (either weight or volume), and then k+ 1 starts. As long as it is greater than d, we will choose, otherwise we will not choose.
