Thanks Kish, you are right. I notice that the XPRESS-MP Student Release
12.20 is loaded. However I'm using ECLiPSe 5.5 now. Could you tell me where
and how I can obtain the OEM version please? Thanks again.

Edwin

Edwin,

Which version of ECLiPSe are you using? A limit on problem sizes was imposed
if you were using Xpress MP in `student' mode (i.e. if you did not have a
license for it). However, since ECLiPSe 5.5, we have obtained an agreement
with Dash (makers of Xpress MP) to distribute an OEM version of Xpress that
does not have this restriction.

Cheers,

Kish
