BOUNDS
b_con [ , b_con…] ;
where b_con is given in one of the following formats:
number operator parameter_list operator number
number operator parameter_list
parameter_list operator number
and operator is or .
Boundary constraints are specified with a BOUNDS statement. One- or two-sided boundary constraints are allowed. The list of boundary constraints are separated by commas. For example,
bounds 0 <= a1-a9 X <= 1, -1 <= c2-c5; bounds b1-b10 y >= 0;
More than one BOUNDS statement can be used. If more than one lower (upper) bound for the same parameter is specified, the maximum (minimum) of these is taken. If the maximum of all lower bounds is larger than the minimum of all upper bounds for the same variable , the boundary constraint is replaced by defined by the minimum of all upper bounds specified for .
