Java: how to represent graphs?

Question

I\'m implementing some algorithms to teach myself about graphs and how to work with them. What would you recommend is the best way to do that in Java? I was thinking somethi

Answer 1

Even at the time of this question, over 3 years ago, Sage (which is completely free) existed and was pretty good at graph theory. But, in 2012 it is about the best graph theory tool there is. Thus, Sage already has a huge amount of graph theory material built in, including other free and open source stuff that is out there. So, simply messing around with various things to learn more is easy as no programming is required.

And, if you are interested in the programming part as well, first Sage is open source so you can see any code that already exists. And, second, you can re-program any function you want if you really want to practice, or you can be the first to program something that does not already exist. In the latter case, you can even submit that new functionality and make Sage better for all other users.

At this time, this answer may not be that useful to the OP (since it has been 3 years), but hopefully it is useful to any one else who sees this question in the future.
