Using epsilon vs lambda

[eliotwrobson]

What is the difference between 𝛌 or ε in an Automaton Theory context? I've seen both used, sometimes seemingly interchangeably, to represent empty string.

@caleb531 looking over this, I think there are a few places where the current library code is inconsistent with this theory (i.e. we use the term "lambda transition" instead of "epsilon transition"), but I'm not sure it's worth changing the API. In all instances, I think people know what is meant.

@EduardoGoulart1 @khoda81 do either of you have thoughts on this?

@eliotwrobson I agree, in some references, they are used interchangeably and it is clear enough what it means...

[caleb531]

@eliotwrobson I also agree. I think as long as people are able to easily intuit what we mean (which seems to be the case)p, that's the most important thing.

@caleb531 Agreed. Going to go ahead and close this. If we get feedback that this is confusing for people we can revisit then.
