Hello Doru,

While porting the VW version of the lattice construction algos, the most adequate representation for VW data structures was provided by Mondrian so I used it.

Mistakes happen. But, it is important to learn from them :)

Now, I'll place them in Moose-Algos-Graph...

I am not sure what you mean. I did not mean that you should move the Lattice classes in Moose-Algos-Graph. The Graphs should not depend on FormalConceptAnalysis. I was just saying that the Lattice is merely a support for creating a graph out of the FCA algorithm. In the VW version, it was also a visual class, but it does not have to be. It should only contain the logic of building the graph. Maybe for this purpose you can use the Graph concepts. The display can be later build using a Mondrian script.

Ok for the tests. I'll start creating them now.

Please put them in the newly created package (Moose-Tests-Algos-FormalConceptAnalysis).

Doru

I'll commit another version in the evening.

thanx
Usman

I looked a bit more. The code from Lattice and LatticeNode depends on the logic of Mondrian. This should best be replaced with code that exists in Moose-Algos-Graph.

In the meantime I also created the Moose-Tests-Algos-FormalConceptAnalysis package and added it to the configuration.

Cheers,
Doru
