Hi,
I have a problem when adding an inequality constraint in the form of
X[2]*X[2]+X[1]>=0 that seems not to taken into account by the optimizer
My C++ code looks like:
static double InequalityConstraint(const std::vector<double>& x,
std::vector<double> &grad, void *data)
{
return (x[2]*x[2]+x[1]);
}
and
opt1.add_inequality_constraint(InequalityConstraint,NULL);
(opt1 is my nlopt::opt )
I cannot figure out why this constraint is not taken into account!
Best Regards,
Adel
