Hi Lang,
I read the papers regarding PBQP and it seemed like it has the potential
to be useful for the single register of PIC16, (maybe an overkill but it
has been working fine so far). I was wondering if you can let me know a
little bit about the nature of your modifications. I see that you have
mainly refactored the code into C++ classes, but have you also made
algorithmic changes?

Thanks
Ali
