[Coin-discuss] problem with deleteRows

[John J Forrest]

Anureet,

A new function compressRows seems to have newly appeared in
CoinWarmStartBasis and fails if a null basis exists.  It is fine for normal
use but you encountered this problem.

I have fixed problem and your small test runs successfully.  I hope you
have no more problems in your use of Coin.

dear sir,

Thanks for fixing the code, which now accepts the "LI" tag in the .mps
format.

There seems to be some trouble while deleting the rows in
OsiClpSolverInterface. A small code to reproduce this problem can be found
at:

http://www.andrew.cmu.edu/user/anureets/tmp/workspace.tgz

The code reads an IP (test.mps), removes all but the last two rows of the
IP and adds a single row. For some reason, the code crashes. (I am using
the latest version of Clp which I downloaded today, 4/20/2006).

It would be very helpful if someone could suggest what is going wrong.

regards,
anureet
