Swift has a garbage collector.

Check chapter 5.

There is a lot of data on this topic.

This is a good starting place: http://www.amazon.com/Garbage-Collection-Algorithms-Automati...

Very nice presentation!

In A* if you use a heuristic to select an edge (using a priority queue, i.e., your #3) it gives a best-first search. But it is is possible to just use a stack/queue an forget about the heuristic, then you get a nice generic way of tree (graph) traversal.

Regarding your use of white/black/grey lists: in a tree (which is acylic), you would only need a list of nodes to visit, however, in a general graph you need to keep a list of nodes that you have already seen/visited so as not to get into a cycle when the graph is cyclic. In tracing garbage collection algorithms this is often used because the live program data generated by the mutator is cyclic, or at least potentially can be. Thanks for mentioning this, though I know my way around gc stuff, too, I would have never come up with this link here! Probably it is a good advice to anybody interested to spend some time reading into garbage collection algorithms, they contain many interesting algorithms on graphs, such as the Deutsch-Schorr-Waite algorithm for tree traversing without requiring an additional stack. The definitive book on garbage collection is 1996's Jones and Lins: http://www.amazon.com/Garbage-Collection-Algorithms-Automati...

Programming Language Pragmatics by Michael L. Scott: The explanations of many things I'd read in other sources are no less than fantastic, I now understand a bunch of things I had only superficially "got" previously. http://www.amazon.com/Programming-Language-Pragmatics-Third-..., check out the overview and reviews.

Coders at Work by Peter Seibel: By far the best of this type of book (well, not counting the '80s classic Programmers at Work which I haven't read since then), one of the best Lisp authors interviews in depth a lot of really interesting and/or important people, from James Zawinski to Donald Knuth, with Javascript, static FP and PARC people, Guy Steele, Peter Norvig, Ken Thompson, Fran Allen (really important interview which points out how C/C++ to the exclusion of truly high level languages have been a disaster when used beyond their proper niches), etc. All are masters who've gotten their hands dirty, many are theory people as well. http://www.amazon.com/Coders-at-Work-Peter-Seibel/dp/1430219...

Garbage Collection by Jones Lins: Pretty much the only book in the field (except for the forthcoming Advanced Garbage Collection sequel in the middle of this year), covers the territory as of the mid-90s. Much more fun than trying to track down 100 individual papers and trying to make sense of it all. Exposition is clear and you get a real feeling for the subtleties of the field (especially when you try fun things like generational and/or concurrent GC). http://www.amazon.com/Garbage-Collection-Algorithms-Automati...
