I'm trying to give a meaningful definition for NFAs with more than one initial state. I know from the formal definition in Wikipedia that it is possible to have more than one initial state, it mentions that "There is an easy construction that translates a NFA with multiple initial states to a NFA with single initial state, which provides a convenient notation."
I believe the power set construction could help me on this matter but I'm having a hard time understanding it. It could probably be modified so that it can be applied into the definition I want to give, but i don't know how.
I would appreciate any help I can get on this matter.
