Hi All,
It is my understanding that LOKI was never distributed as a proprietary
or open source bot. Is it against the terms of the license to use the bot
for personal or academic purposes if you don't distribute the software to
third parties? POKI on the other hand was incorporated into poker academy,
and so was sparbot (PSIOPTI). Both of these use hand strength and potential
calculations that were at least originally based on this library. I'm sure
that the poker academy crew duplicated the functionality when they turned
into published software. It is my (naive uneducated) understanding that you
can do whatever you want with the library if you don't distribute your work.
Thus, I don't see any conflicts with submitting something with components of
pokersource to the AAAI competition. Please correct me if I'm wrong.

I was not aware of this. Most likely he did not pay attention to
the licensing terms. It is a frequent mistake among researchers and
even in the industry. It was a long time ago.
When this happens and we become aware of it, we kindly ask the
person to switch to another software. Of course, there always is the
option to publish the software under a Free Software license that is
compatible with the GNU GPL. But that's for the author to decide, not
for us to impose. All of them have always been very respectful of our
copyright and I'm confident this will continue to be the case.
I don't think University of Alberta is still using poker-eval.
Their proprietary software is widely distributed and I think they
would not have taken the risk of being in violation of someone else's
copyright.
