When developing a software which aims to prove something, it seems
necessary to be able to return something in
{True, False, Indeterminate}.Of course, there are many possibilities to do this, but is there a "canonical" one in Sage ? In C++, for example, there exists the Boost Tribool library (http://www.boost.org/doc/libs/1_62_0/doc/html/tribool.html#tribool.introduction) . t.d. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
