<p>1) Setting CbcModel::setSpecialOptions(32|specialOptions()) should make CbcModel keep names. Not sure if it still works.<br>
<br>
2) If you do preprocessing outside CbcModel::branchAndBound and pass in CglPreProcess xxxxxx into MyHeuristic before adding MyHeuristic to CbcModel then you can use xxxxxx.originalColumns() to see which ones were kept. You could also access xxxxxx.originalModel() to get at names, which may be a cleaner method than 1).<br>

I'm having some troubles (2 in fact) and I hope someone could guide me.<br>
<br>
1) Suppose I've created a class MyHeuristic extended from CbcHeuristic. Now, would I be able to recover the variables names from inside MyHeuristic::solution(...) method? I've wrote my code based on driver4.cpp. Even setting osidiscipline to 2 it won't work. It prints the default names only (from solution(...) method). <br>
<br>
2) There is a way(inside Cbc) to know which columns were dropped after the preprocess?<br>
<br>
Thanks!<br>
