Thanks. After spending some time with the code, I'd rather replace it. There are unreported security issues with its use of /tmp, and it's just generally pretty fragile. It also looks like a more reliable (but often slower) implementation has been added to flint in the meantime, as qsieve_factor(). On the examples I've tried, FlintQS is usually capable of factoring a product of two primes, and relatively quickly. Switching the implementation to qsieve_factor() slows it down a bit (2s to 3s, for example). However, in cases like qsieve(329884789374968270239373010571299817801707558079749117449) which is a product of THREE primes, FlintQS gives you the wrong answer in four seconds whereas qsieve_factor() takes six to get it right. Number theorists, please speak up if you prefer to get less reliable answers more quickly in some scenario that I haven't imagined. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
