As a result; include a “dummy spot†(say D5) with zero transportation cost and equilibrium need that's big difference in offer and desire (= 100 models).Omitting types is usually thought of a bad apply in system parameters or technique return forms for public APIs. While utilizing def in a local variable is not really a problem because the visibility of the variable is limited to the strategy itself, while established on a technique parameter, def might be converted to Item in the strategy signature, which makes it tricky for consumers to learn which is the expected kind of the arguments.
