[BCP] Dual ray is wrong!

[mohamad reisi]

Dear Laci,

As you said, I am doing column generation.
I transefered my code to version 1.1.3. it seems that the dual value are a little better. But they are wrong yet. It is so strange for me! What can I do? 

Mohamad.

Hi Mohamad,

The cvs version is rather old... There has been relatively little 
change in the interfacesince then, but a fair amount under the hood, 
and especially clp/OsiClp has changed a lot. If you could port your 
code to version 1.1.3 and let us know if you still experience 
problems, that would be great. (Since you get the dual rays, I assume 
you are doung column generation. versions 1.2.x still have some column 
generation related bugs, that's why I suggested 1.1.3.)

Thanks,
--Laci
