I was trying to use the empty WarmStart to 'reset' the solver state. Seems to work fine for that in CLP. <br><div class="gmail_quote"><div>Admittedly, the docs don't specify that that's what is should accomplish.</div>

</div> Exactly as documented in the doxygen doc'n --- it returns an empty<br>
warm start object of the correct type for the solver. Dylp, for example,<br>
subclasses CoinWarmStart. Off the top of my head, I don't know if any<br>
other OSIs do the same.</blockquote><div> <br>SYMPHONY does as well.<span><font color="#888888"><br><br>Ted<br>-- <br></font></span></div></div><span><font color="#888888">Dr. Ted Ralphs<br>
