Simplify expressions involving Max(x,y)

[ry...@kinnear.ca]

Is sympy capable of performing these types of simplifications:

Max(a + b, a + c) = a + Max(b, c)
Max(ab, ac) = aMax(b, c)

If not, what is the reason?  How difficult would it be to add this type of functionality?

Best Regards

I don't think it does. It probably would be easy to implement. One
should just implement MinMaxBase._eval_simplify.

For the Max(ab, ac) = aMax(b, c) case, I believe a needs to be
nonnegative. For instance, Max(-1, -2) is -1 but -1*Max(1, 2) is -2.
