Good morning T.Paula Piexoto and first of all : thank you for the great job you’v already done with graph-tool. I am physicist and I am trying to deal with multilayer large (|E|=10^6) graphs. This largeness is basically the reason why i get seduced by graph-tool. I am trying to find a way to *creat* and *filter* graphs G(E,V,D) according to the dimension D of sets of nodes and keep edges between them to perform common mono-layer graph’s operations with it. <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/t496105/Network_of_layers_in_multilayer_systems.png> Multilayered-network with dimension D in (1,2,3,4), each layers C(D) are linked with each other with edges. (Reference : https://en.wikipedia.org/wiki/Multidimensional_network ) I’m asking myself if you have designed such a thing in graph-tool and if, maybe, you have some examples to show how to do that. I hope I didn’t missed this case in the documentation you have provided… Best regards M. Vigouroux -- Sent from: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/
