Hi,
I'm an Italian student, who's studying shortest paths algorithms, I ask to you if you can give me an advice about programs to develop my project. I don't know what kind of program I can use,I know java, but I'm not a very good programmer.
Thank you for all and sorry for my english.

Your English is fine but what is your problem about then? About Java programming
or about shortest path algorithms? If it's about Java start off by implementing a
'heap'; you can find an implementation of a heap in the Java Articles section which
discusses the heap sort algorithm and of course Google knows a lot about heaps
too. Heaps are often used in shortest path algorithms where there is no maximum
(small) bound to be found on the path's cost.
kind regards,
Jos

Thank you for the answer, I would say that I'm looking for the programs,except java, to simulate shorthest paths algorithms.

If you google for 'Dijkstra' and even 'Shortest path' you'll find lots of algorithms in
pseudo code that can do the job: either a 'single source, single destination', or
an 'all pairs' algorithm or a 'single source, multiple target' solution.
It's no use to come here and ask for a boilerplate Java solution, so if you're having
trouble understanding those algorithms please ask specific questions; I like those
algorithms.

Hi, try to build a minimum spanning tree of your graph, this can be achived by first creating a hash table, itorator, and list as you core datastructures to build you graph(?)--> hope you know what it is,"something with vertex(s) and edge(s)" as suggested you can use amongst other shortest path algo, dikstra, etc... i have done this project recently and can post it to you if you like....
Hi samido,
Unluckly I Know what is a graph, expecially a digraph :) I can represente the graph with tree or matrix.
I Know the algorithms do the shortest paths problem;,unlickly I decide that I'll use eclipse for my project. Thanks for the answer and the helping.
Well then, I understand that this is a Java problem after all; for starters first have
a look at the PriorityQueue class (it's a heap; very usefull when you want
to implement Dijkstra's algorithm and others).
kind regards,
Jos
