Re: Re: Re: Re: octave-glpk MIPGAP

I agree that the Tommasso implementation is more complete. Unfortunately, at that time Tommasso and I could verify that his implementation presented a strange behavior for small values of GAP.

In the last conversation we had, he said he would try to fix that. If he has already fixed, apply his patch would be perfect. Otherwise, once that the current implementation is working fine, we could just apply the patch that I suggested, while his code isn't ready.

Once the patch is very simple and successful tests have been done, I see no technical problems to add this feature in the next release, however you guys who knows the correct time for the things here.

Anyway I will submit the patch and demonstrate how it works!

Thanks,

Marcelo.

It's been some time, but reading through my log of this conversation,
there were two competing implementations, one seemed more complete
than the other, and I asked for some tests that demonstrated the
correctness of the implementation. Preferrably of the more complete
one. It seems you only cared about one particular feature of GLPK,
whereas Tommaso had a more comprehensive patch that included yours as
a special case.

I don't understand GLPK and at the moment with the impending release I
don't want to spend time learning, but if you could please provide the
patch again and in the patch write some tests to demonstrate how it
works, I will be happy to push it, or perhaps someone else will.

Please submit the patch to our patch tracker so it's less likely to be
forgotten:

Octave 3.6 is about to be released, so I'm not sure if this feature
will make it in time for the release. We're right now in the
stabilising phase of the release, so I don't think this is a good time
to add new features to 3.6. It may have to wait until a future stable
release of Octave.
