极限猜测算法

本文介绍了极限猜测算法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

你好，你好， 我正在寻找一段代码，最好是用Python代替，以下代码将是b / b 。它将接受函数的一些数据点（x，f（x）），当x收敛到无穷大时，它会收敛到某个有限值。我需要算法来猜测这个限制是什么，无论它的精度是多少......它都可以。 例如，如果输入是： [ [1,8]， [2,7.5]， [3,7.25]， [4,7.125] ] 然后输出为7.或者至少接近一些。 有没有人知道这样的事情？

Hello hello, I''m looking for a piece of code, preferably in Python, that will do the following. It will accept a few data points (x,f(x)) of a function that converges to some finite value when x converges to infinity. I need the algorithm to guess what that limit is, to whatever precision it can. For example, if the input is: [ [1,8], [2,7.5], [3,7.25], [4,7.125] ] Then the output will be 7. Or at least something close. Does anyone know anything like that?

我建议任何入门微积分或数学分析文本。甚至可能是你教授为你指定的课程:-) 查看限制在目录中。

I suggest any introductory calculus or math analysis text. Perhaps even the one your professor assigned you for the course :-) Look under "limits" in the table of contents.

我是第三年的数学本科生。你可能不明白我的问题。

I''m a third year math undergrad. You probably did not understand my question.

我想我理解这个问题。这听起来像一个数值方法 作业问题。基本上你有f（x0），f（x1）等，你想要 来推断x =无穷大。提示：想想a0 = 1 / x0，a1 = 1 / x1等等。 所以你的初始数据是f（1 / a0），f（1 / a1）等等它应该是非常好 明显该做什么。

I think I understood the question. It sounds like a numerical methods homework problem. Basically you have f(x0), f(x1), etc. and you want to extrapolate to x=infinity. Hint: think of a0=1/x0, a1=1/x1, etc. so your initial data is f(1/a0), f(1/a1), etc. and it should be pretty obvious what to do next.
