<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>

What does the following message mean :<br>

<div>
<div>Reinitializing primal norms . . .<br>
Computed 1 new norms.<br>
Initializing primal norms rowwise . . .<br>

produced each time a column is added ?<br>

<div>So much time (several seconds) is spent between each of

It appears at each column generation iteration.<br>
Then the LP is re-optimized.<br>
