graph's Issues

reset() API not working

API's reset() function is not working properly.

It just removes the first vertex and two first nodes.

The Big Unknown Bug (BUB)

It seems there is a bug (a Big Unknown BUG aka BUB) that affects the underlying engine of Graph and renders many functionalities useless or buggy.

For now we are not sure where BUB is, and this issue will be the reference issue for other functionalities affected by BUB.

Notebook History

It would be great if we could access notebook history by arrow keys.

disconnect() API not working

API's disconnect() is broken.
It is BUB for sure.

More investigation is required.

API function to check existence of edge in graph.

There is a need in API function to check if graph has specific edge.

The function should be like this:

hasEdge( start, end)

GetDotByDotOrId will not check the validity of the id

Abstraction Layer's GetDotByDotOrId will not check if the given id number exist on graph or no.

Matrix View

So the matrix view is a bit of a problem. As mathjax normally doesn't work on node.js you have to run the mathjax-node which doesn't work either. then there is this project magnetite (which is also not ready yet) and it has a very interesting point:

• Using BrowserWindow from electron

And it seems that it won't work in the future. That's why I started to port one of my web tools: Notation and it seemed to work quite well with matrices and you can find a demo here:

• Notation with Matrixes

But it seems to not to wok on Graph. So let me play a bit more and see what happens....

Dot GetNeighbors not working

Dot's GetNeighbors is not working properly and can't find right neighbours of a Dot.

It seems to be related to BUB.

connect() API always returns false

API's connect() method always returns false.
The reason is obvious in code. it will be fixed soon.

disconnect() API deletes just inputs or just outputs

API's disconnect() method deletes just Inputs or just Outputs.
but becasue the connections are two way connections, the both Inputs and Outputs should be deleted.

The reason and the Fix are obvious and will be patched soon.

Weighted Graphs

Dot GetNeighbors is slow

Dot's Current GetNeighbors algorithm is somehow slow.
It checks all Inputs and Outputs of ALL nodes.
It seems it can be so much optimized.
