Yes. What's more, the constraints need not be linear. (However do not expect great speed.) In[9]:= Minimize[(-x)*y, {x^2 + y^2 <= 1, x >= 0, y >= 0}, {x, y}] Out[9]= {-(1/2), {y -> 1/Sqrt[2], x -> 1/Sqrt[2]}} Of course this means that the maximum is In[10]:= -%[[1]] Out[10]= 1/2 at In[11]:= {x, y} /. %%[[2]] Out[11]= {1/Sqrt[2], 1/Sqrt[2]} Andrzej Kozlowski Toyama International University JAPAN http://platon.c.u-tokyo.ac.jp/andrzej/ On Thursday, June 13, 2002, at 03:38 PM, Leonard Wapner wrote: > Is there a Mathematica function allowing me to maximize the product "xy" > over a set of linear constraints?
