New issue 4075 by [email protected]: More efficient to_cnf
http://code.google.com/p/sympy/issues/detail?id=4075
to_cnf needs to be more efficient. For some expressions, it takes forever
and produces huge expressions, which tend to have tons of unnecessary
clauses (lots of x | ~x).
I googled, and http://gauss.ececs.uc.edu/Courses/c626/lectures/BDD/st.pdf
looks like it might be an algorithm. Any kind of optimization would
probably help. Right now, it just does the naive distribution.
