Good Java graph algorithm library? [closed]

Answer 1

Summary:

• JGraphT if you are more interested in data structures and algorithms.
• JGraph if your primary focus is visualization.
• Jung, yWorks, and BFG are other things people tried using.
• Prefuse is a no no since one has to rewrite most of it.
• Google Guava if you need good datastructures only.
• Apache Commons Graph. Currently dormant, but provides implementations for many algorithms. See https://issues.apache.org/jira/browse/SANDBOX-458 for a list of implemented algorithms, also compared with Jung, GraphT, Prefuse, jBPT

Answer 2

http://neo4j.org/ is a graph database that contains many of graph algorithms and scales better than most in-memory libraries.

Answer 3

If you are actually looking for Charting libraries and not for Node/Edge Graph libraries I would suggest splurging on Big Faceless Graph library (BFG). It's way easier to use than JFreeChart, looks nicer, runs faster, has more output options, really no comparison.

Answer 4

If you were using JGraph, you should give a try to JGraphT which is designed for algorithms. One of its features is visualization using the JGraph library. It's still developed, but pretty stable. I analyzed the complexity of JGraphT algorithms some time ago. Some of them aren't the quickest, but if you're going to implement them on your own and need to display your graph, then it might be the best choice. I really liked using its API, when I quickly had to write an app that was working on graph and displaying it later.

Answer 5

http://incubator.apache.org/hama/ is a distributed scientific package on Hadoop for massive matrix and graph data.

Answer 6

JGraph from http://mmengineer.blogspot.com/2009/10/java-graph-floyd-class.html

Provides a powerfull software to work with graphs (direct or undirect). Also generates Graphivz code, you can see graphics representations. You can put your own code algorithms into pakage, for example: backtracking code. The package provide some algorithms: Dijkstra, backtracking minimun path cost, ect..
