<div>Hi,</div>
<div> I am using the C++ version of Ipopt. I have a class which inherits from TNLP and I provide an implementation for <strong><em>intermediate_callback</em></strong> in my derived class. But the execution never reaches my implementation. </div>
<div> </div>
<div> Can someone suggest something? Is there some option that needs to be set?</div>
<div> </div>
<div>Regards,</div>
