Any tips on the best way to access a subgraph - ideally without the memory overhead of copying the subgraph to a new object. I want to pass each component of my graph to an algorithm separately, but in some cases the original graph will only have a single or a few component(s), in other cases there will be many. Maybe I will do it differently depending on how many components I have. Any tips welcome.
