Thanks, Peter. That was clever and email is very enlightening. I
have analogous idea for more compact conflict matrix representation.
I am currently working on bit matrix compression. It is not
implemented yet. I hope it will be ready in a week.
vlad, this seems like the wrong way to go.
Vladimir, if you feel that Peter's code cannot be used directly in
IRA, would you please explain why not? It does seem like it would be
easier for everyone if we could leverage what has already been done.
Sorry, Mark. I believe I already explained in my previous email why the
code is hard to incorporate into IRA. It is just more easy to add one
missed feature into IRA conflict infrastructure.
I am not going to ignore all Peter's code. After some investigation, I
decided to use sparsets implemented by Peter and Janis. It is already
implemented and easy to use and there is no harm in using this, only
potential improvement in compiler speed (although most probably this
improvement will be insignificantly).
