[sage-devel] Re: symbolic logic code

Hi! You could wrap that functionality around PolyBoRi Using the mapping: False -> 1 True->0 or -> * not x -> 1+x You can map logical expressions to Boolean polynomials. Having such a polynomial f, you calculates its zeroes, which gives the DNF. Example: In [1]:f=(x(1)+x(2)) In [2]:(x(1)*x(2)).
