Discuss cost functions

[fxjung]

How should cost functions be implemented/specified and which dispatchers/cost functions should go into the main repository?

Deb:

Thanks. After reading your replies, I would like to start a discussion on the merits of the distance minimization + user-selected external cost pattern. Especially:

• What is the use case?
• Will that use case + potentially other use cases be more effectively taken care of by a different design, e.g. a modular notion of cost.
  Users should be able to implement dispatchers of their own liking externally as well, not everything should go into ridepy, as far as I understand. Maybe the zero detour stuff should also be refactored this way...

Cost functions may have distinct "goals". Suitable candidates might

• minimize the detour that results through any new insertion
• minimize a quality-of-service parameter for the customer, e.g. the dropoff time
• maximize efficiency, i.e. the quotient of sum of the direct requested times/distances and the resulting driven time/distance
