Purpose
Synopsis
int XPRBdelqterm(XPRBctr ctr, XPRBvar var1, XPRBvar var2);
Arguments
|
ctr
|
Reference to a constraint.
|
|
var1
|
Reference to a variable.
|
|
var2
|
Reference to a variable (not necessarily different).
|
Return value
0 if function executed successfully, 1 otherwise.
Example
The following example first adds the term
5.2*x2*x2 to the constraint
ctr1 and then deletes this term from the constraint:
XPRBctr ctr1; XPRBvar x2,x4; ... ctr1 = XPRBnewctr(prob, "r1", XPRB_L); x2 = XPRBnewvar(prob, XPRB_PL, "abc1", 0, XPRB_INFINITY); XPRBaddqterm(ctr1, x2, x2, 5.2); XPRBdelqterm(ctr1, x2, x2);
Further information
This function deletes a quadratic term from a constraint, comprising the product of the variables
var1 and
var2.
