Question About RPNI #133

Hi, I'm Sangjun Park who is interested in your project.

When I go through your Project, there is a RPNI learning algorithm that can learn DFA with Positive and Negative Set.

However, i'm curious when use it for Mealy Machine, my question is that "Is it possible to define negative set in Mealy Machine?"
I mean in network packet trace, how can i define negative set of network trace?

And Can you give me a simple example for using RPNI algorithm?
I think there aren't good example for this.

Best Regards,
Sangjun Park
