<div>Step 4 is actually the only one that seems to work (that is 1,2,4,5,6 works). Instead doing 1,2,3,5,6 gives me</div>

in step 5.

<div>Am I missing some other step?</div>

<div dir="ltr">Hi,<br>
<div><br>
</div>
<div>I have a model I would like to solve, and then add a constraint and change the objective, and then solve again. My understanding of the necessary steps is:</div>
<div><br>
</div>
1. SCIPenableReoptimization(true)<br>
2. [Create and solve model]<br>
3. SCIPfreeReoptSolve<br>
4. SCIPfreeTransform<br>
5. [Add new constraints and change objective]<br>
6. [Solve modified model]
<div><br>
</div>
<div>This doesn't seem to work as it is, but when omitting step 1 and 3 it works. I guess the other steps are also important, right?</div>
<div><br>
</div>
<div>Thank you</div>
<div>Marco</div>
