To maximise f(x,y), minimise -f(x,y)
Ooops .. yes of course!

Hello all,
I would like to maximize or minimize a given math function over a
specific set of values, in Python preferably.
I was checking out Wolfram Alpha (http://www70.wolframalpha.com/)
and it can do simple optimization problems in math, such as
maximize 15*x - x**2 over 0 to 15
