A feature that would make the program better is being able to zoom. Being able to zoom by pressing ctrl and +, - or ctrl and scroll wheel.

The horizontal line separating the tree area and the top bit is hard to resize because the area that the resize handle appears is so small that it is hard to do on a touchpad

I got this error when I run the help:

java.lang.UnsupportedOperationException: Desktop API is not supported on the current platform.

It closed GraphTea.

Also, when I click on "more" in the welcome message on the status bar.

Coloring are not correct. For the bug generation, use Banana Tree with default parameters, i.e. (3,3) and check coloring. However it seems that the report of chromatic number is correct.

make the representation of the matrix more beautiful. :)

Hello,

I am a teacher in France.

Thank you very much for this beautiful software.
I begin to use it.

Sometimes there is an error using Dijkstra's algorithm.
I sent you an example.
BugExample.pdf

Best regards

The Dijkstra algorithm provides minumum distance 13 between 1 and 6 but actually the minimum distance is 9

U can zoom to some subgraph,
it mean that the other part of graphs are just a imagical representation.

UPDATE:

Pulled a new request solving it

Pull request

Working on GraphTea newrooz 1.5.4
Reports -> General -> Is Eulerian?

Doesn't work properly in my graph, as you see all the vertices have even degrees so it should be an Eulerian graph, correct me if I am wrong.

It would be nice if edges have delay property .(transit time of the edge)
So following algorithms could be added to GraphTea based on delay of edges :
1-maximum flow over time
2-quickest flow over time
3-earliest flow over time
...

i don't see Maximum Weight Branching (with condensation process) feature, i hope next time this feature can be added for enhancement.

get rid of xml representation and introduce json to be able to save/load and cut/copy/paste and connect to other programing languages using redis.

After selecting vertex nothing happens,
no tree is shown or calculated.

Using reports though,
an array solution is given (u can choose the starting point)

Hello,
Recently I tried to generate a latex drawing for a graph and I cannot get the same look as the one I generate in the program. Is there something specific I should do to make it work?

I just clone the repo and tried to build the project but to no effect

Error: Unable to access jarfile binary/graphtea-main.jar 

we had a action based undo / redo, which was very problematic. for every action we had to define undo and redo methods. then we switched to a time based undo / redo , which saves the graph state every two seconds. this makes it easier to write new actions and extensions, but still is not finished.

currently it save the graph state in json. it can be other things like our new simplegraph format. we should think about a good format, and the rest is almost done. the code is at:

UndoManager, UndoAction, RedoAction

In my opinion the regular graph with 16 vertices each of degree 7 is the model for the sudoku 4x4.
Therefore the chromatic number is 4 but GraphtTea says 6.
Who is right?
Thanks

it is like this:

it should be like this:

this is very important issue, because banana tree is the most used generator in graphtea. probably because it is the first item in the generate menu

Hi guys. I just started using GraphTea and I can't work out how to draw an edge from a vertex to itself. Can you let me know how to do this? Sorry if I'm missing something obvious.

I am trying to install the software on ubuntu 15.10. It keeps complaining about the java -jar graphtea-main.jar file. Even the deb version of the software doesn't make a software icon so I can find it in the software library of installed software.

Hi!

I'm currently working on Debian's graphtea package. During the build process, we create the following symlink:

adi@foh:~$ ls -lh /usr/bin/graphtea
lrwxrwxrwx 1 root root 35 Apr 23 17:16 /usr/bin/graphtea -> ../share/graphtea/graphtea-main.jar

However, executing graphtea results in

adi@foh:~$ graphtea
There is no directory with name plugins.

When I run it from /usr/share/graphtea instead, it works as expected.

So graphtea has the notion of always running from a directory in which it also finds the plugin/, extensions/, and lib/ subdirectory.

I've started to make graphtea find its own plugin directory by querying the location of the current jar file. See commit ecb8c8e

Unfortunately, this is not enough. The GUI starts, but the "Generate graphs" menu item is empty. I have absolutely no Java experience, so somebody who knows graphtea should have a look. In the end, it should be possible to say

$ java -jar /path/to/graphtea-main.jar

with full functionality, e.g., omit the "cd binary/" and try

$ java -jar binary/graphtea-main.jar

instead. This has to work.

Cheers

The reset button resets the color of the graph to a constant color "0". It is not correct when the user changes the color of the vertex.

Clicking the download button for Windows causes the following message to appear: We're sorry, but something went wrong.

I have been searching for this feature in the program and I didn't find it (sorry if already exists and I didn't see)

the basic algorithms like dfs and bfs are very old cold. we need to rewrite them with the modern styles presented on :

IsEulerian still doesn't work because isConnected fails due an error on the dfs function on AlgorithmUtils.java, seems that it only gets executed once. (tried debugging it by myself but I am not familiar with java and the project itself yet).

The code of the faulty dfs function it's this one:

public static <VertexType extends BaseVertex, EdgeType extends BaseEdge<VertexType>>
void dfs(BaseGraph<VertexType, EdgeType> g,
         int node, ArrayList visit, int parent[]) {
    visit.add(node);
    ArrayList e = getAdjList(g);
    ArrayList neighbors = (ArrayList) e.get(node);
    for (Object neighbor1 : neighbors) {
        int neighbor = (Integer) neighbor1;
        if (parent[neighbor] == -1) {

The maximum flow report generates exception sometimes, for example for Generalized Peterson (20,5)

when a lot of reports are open, some parts are un-scrollable

Edge Weight is of type integer; this is a undesirable limitation of the tool as sometimes weights are decimal values. I have re-coded the tool to utilize Double instead of integer within a few hours, however reading old data files fail, thus this version is a major change.

I did not investigate the file format to see if there is versioning information held that would allow a conditional check, but if that version number is not in the file, you should consider it for future releases.

Hi,
I have windows 8 as OS (he systems is 64 bit). I receive this error while installing :
Windows can't find javaw.

I have changed the weights of edges, I click "Show weight" but nothing appears. Thanks
