```Dear MathGroup,

<wolfrum at cs.uni-bonn.de> asked the question below, and
several fine answers have been posted.

I have a related question.... What if the constraint:

abs(x+y) = 1

is replaced by a new constaint:

abs(x+y) <= 1

How can one solve a problem like this in Mma?? Thank you for your help

Dave
