I'm writing on an english article in the domain of navigation and geographic routing. I have a use case for targetless navigation but I'm unsure if the term is the correct choise. I see targetless is an existing word in the english language, and it literally means without target.
In my specific use case, and in the oppisite to a traditional A-to-B navigation like you use in your car, I'm looking for a term or phrase that descibres the state that
- I'm in a explorative navigation mode
- I'm free to go where I want (as long as I can reach it somehow)
- Describes something scientists call A-to-N navigation 
Is targetless navigation the term I'm looking for?
 The correct scientific term is the single source shortest path (SSSP) problem class in case anyone wants to read up on that matter.
