[Cmpl] CBC solver not working

[Mike Steglich]

Hello Ainara,

Thank you for using CMPL.

This is actually a strange behaviour. I would like to propose to download the Cmpl v1.11 using the following link: http://coliop.org/_download/Cmpl-1-11-0-win.zip <http://coliop.org/_download/Cmpl-1-11-0-win.zip>

This is the new version … but I have to find a little bit time to release it officially and to update the website.

Cheers,

Mike
