XPRBsetqterm |
Purpose
Synopsis
int XPRBsetqterm(XPRBctr ctr, XPRBvar var1, XPRBvar var2, double coeff);
Arguments
|
ctr
|
Reference to a previously defined constraint.
|
|
var1
|
Reference to a variable.
|
|
var2
|
Reference to a variable (not necessarily different from first variable).
|
|
coeff
|
Value to be added to the coefficient of the term
var1 * var2.
|
Return value
0 if function executed successfully, 1 otherwise.
Example
XPRBprob prob; XPRBvar x2; XPRBctr ctr1; ... ctr1 = XPRBnewctr(prob, "r1", XPRB_L); x2 = XPRBnewvar(prob, XPRB_PL, "abc1", 0, XPRB_INFINITY); XPRBaddqterm(ctr1, x2, x2, 1); XPRBsetqterm(ctr1, x2, x2, 5.2);
This sets the coefficient of the term
x2*x2 to
5.2.
Further information
This function sets the coefficient of a quadratic term in a constraint to the value
coeff.
- Note:
- all terms that are added to a constraint must belong to the same problem as the constraint itself.
