The constraints are defining the constraint matrix A. They are
assumed to be of the "less then" type, but if you have got them
as "greater then" type you may simply multiply both sides with
-1 and change the inequality sign.
If we are going to maximize f (x) =xl + 2x2 and one of the con-
straints are xl-2x2 > 2, then minimize -xl-2x2 with the con-
straint xl + 2x2 <-2.
All independent variables are assumed to be positive or zero.
Rem. The independent variables have the
symbol xi regardless of the symbols used in a
minf(X) = OX A*X<B
