Constructor Detail

XPRBrelation

public XPRBrelation(XPRBexpr l,
                    int type)

Create a linear relation.

     XPRBprob expl2;
     XPRBvar x1;
     XPRBexpr l1;
     XPRBrelation lr;
     expl2 = new XPRBprob("example2");
     x1 = expl2.newVar("abc3", XPRB.UI, 1, 100);
     l1 = new XPRBexpr(3.7, x1);
     lr = new XPRBrelation(l1, XPRB.G);
 

Parameters:

l - linear expression of type XPRBexpr

type - type of the relation. Possible values:

• XPRB.L <= (inequality)
• XPRB.G >= (inequality)
• XPRB.E = (equation)
• XPRB.N non-binding
