Hi Everyone,
I'm revamping Sets a bit as a precursor to my GSoC project. The first part
of this is creating a FiniteSet object to go along with Intervals (like (0,
1] ) and Unions (like [-1,0) U (0, 1] ).
I changed the default behavior of Interval(1,1) (interval from 1 to 1
inclusive, i.e. [1, 1] ) to be just the FiniteSet {1} .
Unfortunately it appears that Interval(a,a) has been used extensively in the
inequalities module for things like
reduce_poly_inequalities([[Eq(x**2, 1)]], x, relational=False) ==
[Interval(-1,-1), Interval(1, 1)]
My code changes the result to the FiniteSet {-1, 1} which I think makes more
sense. I'm a little uneasy about going in and changing this much in modules
with which I have little experience. Are people ok with this? Is there
anyone I should converse with while dealing with this particular problem?
(someone involved in inequalities)
Best,
-Matt
