<div>hi,<BR> <BR> I am trying to construct a linear program with thousands of constraints. The <BR>algorithm starts with one with a few hundred constraints and then augments <BR>additional constraints dynamicaly. I am using OsiClpSolverInterface to model my LP <BR>object.<BR> <BR> As of now adding each row takes a lot of time. Apparantly the OsiClp object <BR>increments the size of the coefficient matrix only by a small amount in each <BR>iteration. I was wondering if there is a way to instruct OsiClp to allocate <BR>additional space apriori so that adding rows can be done efficiently.<BR> <BR> I am aware that CoinPackedMatrix supports such an operation, but I cannot <BR>access a non-const form the coefficient matrix (can I?) and hence that utility is <BR>of limited use. I must also add that I receive the OsiClp object as an argument <BR>to a function and I have no control over how it is created.<BR>
<BR> Any help is this regard is greatly appreciated.<BR> </div> <div> regards,<BR> Anureet Saxena<BR> <BR></div><BR><BR>Anureet Saxena<br> anureet@cmu.edu<br> anureet@yahoo.com<br> <br>--This mail was delivered to you on 100% recyclable electrons.<p>
