Hi<br>
<br>
I have reused the class CbcEventHandler in my code. I am facing some issues trying to use the pointer model_.<br>
<br>
In the function event, at the end of each node (i.e. whichEvent==node), I need to retrieve:<br>
- the current best objective. I do it using model_-><u></u>getMinimizationObjValue(). This seems ok.<br>
- the best possible objective. I do it using model_-><u></u>getBestPossibleObjValue(). This seems ok.<br>
- the value of a particular variable, say "DUMMY". I have stored the column index of "DUMMY"<br>
when I created the model. I want to get the value of this variable for the best solution.<br>
So I do, double *argmin = model_->bestSolution() and then argmin[INDEXDUMMY].<br>
It just does not work. I am sure about that, because in the instance I have been testing,<br>
it happens that I have the constraints DUMMY = 0 (DUMMY is a continuous variable<br>
by the way)<br>
<br>
Any idea????<br>
<br>
Thanks in advance<br>
<br>
