[Coin-lpsolver] numberBasic<=model->maximumBasic()

[John J Forrest]

Jean-Sebastien,

The initialization of Clp should make sure their are not more basic 
variables than the number of rows.  By line 147 it should be okay. I will 
change assert to cleanup but I would like to know how it happens.

[Coin-lpsolver] numberBasic<=model->maximumBasic()






Hi !

When re-solving linear programs using Clp after providing a WarmStart
information, I sometimes get:

assertion "numberBasic<=model->maximumBasic()" failed: file
"ClpFactorization.cpp", line 147

Could someone please explain me the meaning of this error ? I may be
misusing the WarmStart information, but the error seems very very rare.

Thank you very much in advance,

Regards,

js
