<p>Hi All,</p>
<p> </p>
<p>I am trying to run Bonmin for my application which is an unconstrained MINLP. I am calling Bonmin through a C++ interface.
</p>
<p> </p>
<p>To invoke Bonmin, I need to define a few virtual functions inm y code. </p>
<p> </p>
<p>As my application is an unconstrained MINLP, I will not be defining the constraint variables, constraint functions,function to compute jacobian and the function to compute the hessian of the
<span class="st">Lagrangean ( eval_g, eval_jac_g,eval_h etc. ).</span></p>
<p><br>
<span class="st"></span></p>
<p>By not defining the above function I am initializing the respective vectors, matrices and the variables (number of non zeros in jacobian and hessian ) to NULL but this is causing the solver to fail with a length error.</p>
<p> </p>
<p>I am a rookie to optimization and any inputs as to what I am missing is much appreciated. I guess I am missing something conceptually as I have double checked syntactical/logical correctness of code.
</p>
<p> </p>
<p>Thanks a lot in advance.</p>
<p> </p>
<p>Regards,</p>
