Does this seem strange to you, too?
From the Maple help file (?minimize)

> minimize(x^2 + y^2, {x, y}, {x=-10..10, y=10..20});
                                       0

I'm sorry, but constrained to 10<y<20, the minimum is 100!

Trying it myself:

> minimize(x, {x}, {x=5..10});
                                       5
> minimize(x^2, {x}, {x=5..10});
                                       0

Hmm.  Is this a bug or a feature?  I can't find it mentioned that 
minimize() over a range doesn't work except for a linear equation.
