<div class="moz-cite-prefix">Hi Xavier,<br>
<br>
I can only guess what it means: Probably, the steepest edge norm
for the new column is computed, because we use the steepest edge
pricing method within CPLEX by default. Is there any more
output? But probably the time is spent for solving the LP after
the norms were initialized, CPLEX does not always print output
for that.<br>
<br>
You can also try to change the CPLEX pricing method to something
else, e.g., devex pricing by setting the parameter "lp/pricing =
d" and see how this changes the behavior.<br>
