我以前都不知道cado-nfs
我是个老土,不会Linux,
以前用过Ubuntu的次数不多
不是聪明
只是我见得多
BTW
我之前应该在论坛里面说过cado-nfs的
https://bbs.emath.ac.cn/thread-17199-1-1.html
https://bbs.emath.ac.cn/thread-15851-1-1.html
查了一下
总觉得这次你应该能记住这个软件了
BTW,可以用cygwin安装cado-nfs
但一定要从官网下载最新的git版本
老版本会因为hwloc.h版本过新而不能编译 .·.·. 发表于 2020-7-11 03:58
factorint(10^100+13,11)//用于分解小因子,11的意思是只用Pollard-Brent Rho and Shanks SQUFOF,Poll ...
我一直用的是factor
你居然是用factorint函数! mathematica 发表于 2020-7-13 13:24

factorint更好控制
直接factor会超时
但factorint(..,11)会返回(可能是所有的)小因子 .·.·. 发表于 2020-7-13 14:02

经@无心人提醒,可以用\p 1024设定精度)
有个refcard上面有这个吧???????????? mathematica 发表于 2020-7-13 14:58
