[Coin-discuss] Glpk Osi for interior point?

Hello,
Am I correct in observing that there is no way of using the GLPK's
interior-point solver via OSI? And if so, is there any plan to add this
feature? I have a case where the interior point is at least 50x faster
than simplex, so it would help...
I can, of course, call the lpx_interior method directly, but then the
Osi still does not know about the solution, since all the access
functions (status, objective function and column values) are different
when using lpx_interior...
It would thus help a lot if I could use the interior-point solution as a
starting point for the standard simplex solver. Is this possible? (I
tried setColSolution, but it does not seem to have any effect at all.)
Thanks in advance.
Regards,
Michal Kaut
