<br><font size=2 face="sans-serif">You guessed correctly. Becuase
of the mulitple ways to find covers and the multiple ways to lift you can
easily get duplicates. </font>

enhancement, pls post a ticket to the Cgl ticketing system. https://projects.coin-or.org/Cgl/report/1</font>

<br><font size=3>Is it a bug or a feature if in one pass of CGL Knapsack
I get back the same cut more than once? I am guessing there are different
methods for generating and lifting and it is possible to generate the same
cut twice - and that the generator itself does not check for dups? i.e.,
it leaves that up to the client? <br>
<br>
Or, if I see duplicate cuts, should I suspect a bug (either in CGL or in
my use of it)?<br>
<br>
Thanks,<br>
