yafu的安装与使用

介绍

YAFU (with assistance from other free software) uses the most powerful modern algorithms (and implementations of them) to factor input integers in a completely automated way. The automation within YAFU is state-of-the-art, combining factorization algorithms in an intelligent and adaptive methodology that minimizes the time to find the factors of arbitrary input integers. It is most optimized for general inputs up to 160 digits in size, although there is support for inputs much larger than that, if they have a special form. There are also specialized functions for handling lists of inputs and ranges of contiguous smaller inputs.

YAFU is primarily a command-line driven tool. You provide the number to factor and, via screen output and log files, YAFU will provide you the factors. But that’s not all! You also get an interactive environment similar to MATLAB or PARI/GP, where you can type commands and store results. The functionality of this interface is limited, but perhaps useful, and I have plans to make it better. YAFU also provides a vast amount of flexibility, through many many options and a very capable expression interpreter. If you know what you are doing, or if you read the documentation enough, you can customize the operation of YAFU a great deal. You should have received a copy of docfile.txt, which explains in some detail all of the available functions, how to use them, and how to influence their behavior.

安装

下载地址（windows)

https://sourceforge.net/projects/yafu/

解压即可使用

使用

仅支持cmd 不支持powershell

命令为

yafu-x64.exe factor(要分解的数)

若数字过大，可使用文本文件进行读取

yafu-x64 "factor(@)" -batchfile text.txt

文本文件应在数字输入后增加换行符保存

注意：读取后文件会被删除
