Pinned topic feasOpt in the MATLAB API

‏2013-01-12T18:23:47Z |
In the CPLEX MATLAB API it only seems possible to pass linear constraints to the feasOpt call. Is there any way of to pass quadratic constraints too? I think this capability is available in other APIs, but am keen to know whether this can be done in MATLAB. Thanks!

    You are right. In the matlab API feasopt() can only be invoked for linear problems. Quadratic constraints are not supported here. I have filed a user wish that asks for this feature.
    To get feasopt for quadratic constraints you would have to manually create the model that feasopt would otherwise create: Add additional variables to the quadratic constraints that make the constraints always feasible and penalize the variables if they are non-zero. Then minimize the penalty.
