Hello.<div><br></div><div>I'm very new to CLP and I'm having some difficulties trying to create a base LP, modifying it a little bit (adding or removing rows), solving it and doing this many times. I found some of the examples regarding this subject but it seems that I'm still missing something. The tutorial/wiki/doxygen docs are not very clear about this.</div>
<div><br></div><div>Basically what I'm trying to do is:</div><div>- Create a "base" LP and solve it</div><div>- Add some rows (using <font class="Apple-style-span" face="'courier new', monospace">addRow</font> method), solve the modified LP (using <font class="Apple-style-span" face="'courier new', monospace">primal</font><font class="Apple-style-span" face="arial, helvetica, sans-serif"> method</font>), remove the added rows (using <font class="Apple-style-span" face="'courier new', monospace">deleteRows</font> method)</div>
<div>- Repeat previous step many times, recursively</div><div><br></div><div>What happens is that some state is stored at the model after some iterations that make my model infeasible for a combination of constraints that were already solved before and were feasible at that time. Should I be using some sort of "cleanup" or "reset" method between the calls to the <font class="Apple-style-span" face="'courier new', monospace">addRow</font> method?</div>
<div><br></div><div>I'm using version 1.10.2, under Windows, with Visual Studio 2008. As it was the last packed version available. Should I get a newer one (directly from the svn repository)?</div><div><br></div><div>
Thanks for any help!<br clear="all">--<br>Carlos E. Knippschild<br>
