i am looking to implement a algorithm for the Travel Salesman Problem. I want to model the solution using the graph , in this a vertex will represent a city and edge will represent the cost from one city to another.
At any point i have to compute cost from one city to another like
(cityA, cityB)—>cost
What data structure in java should i use for graph?
And what kind of GUI tool or library can i use to represent a graph ?
If you are free to use external libraries, JGraphT is easy to use.
