please check out question 11 about column generation and
branch-and-price in the FAQ. <a class="moz-txt-link-freetext" href="http://scip.zib.de/#faq">http://scip.zib.de/#faq</a><br>

You can stop pricing earlier and also supply a valid lower bound
(e.g., the Lagrangean bound).<br>

<div>Dear SCIPers<br>
<br>
</div>
I have a CG implementation for which there is a strong
tailing off effect at the root node. <br>
</div>
Attached I draw the development of duals and objective
function.<br>
<br>
</div>
I wonder if there is any way to get out of this situation ?
any parameter setting etc. Any example, any possibility for
aborting the generation of column and going to branching?<br>
</div>
I checked the SCIP mailing list history for similar question
with no avail<br>
<br>

Cheers<br>
