Rows are printed to the display table at various points during the solving process. A line is typically printed after every pricing loop. Also, lines can be printed within the pricing loop. Within the pricing loop, a display line is printed after every 100
pricing rounds. This would be why you are seeing the 3x100 columns being added on some lines while on others only 3 columns are added.</div>

<div dir="ltr">Dear SCIPers,
<div><br>
</div>
<div>I have a branch-price-and-cut application, and am using SCIP 7.0.1. When I set </div>
<div>pricing/maxvarsroot = 3</div>
<div>I get the following behaviour:</div>

<div><font face="monospace"><br>
</font></div>
<div><font face="monospace">So at time 5.7s we have 3 new columns as expected. However for the next two lines we see that 3*100 new columns are introduced.</font></div>
<div><font face="monospace">I have had a look at what is going on in </font>SCIPpricestoreApplyVars and each time it is called we only get 3 new variables priced in. So where do the 100 iterations come from?</div>
