Parameters-----G : NetworkX graph or list of nodes A position will be assigned to every node in G. llay_seg : list of layout’s segments intersected lshP : list of shapely points of intersections. Parity based encodings [ 25 – 27 ] provide a potential alternative to minor embeddings, but the size of fully connected graph which can be represented in a. But I am unable to calculate the length of each edge as line geometries are simplified into start and end coordinates in the output of Networkx. After version 3. Morphisms/Group Actions. We focus on the relationship between network properties and the anatomical layout of the ROI network. highlight_inds (iterable:) - Highlight these edges.

I got as far as tree decomposition but I'm finding the rest very difficult to grasp. networkx can't compute algebraic connectivity. Except for two small cases on 4 pegs, the graph is otherwise not planar, and likely there is a better way to layout the vertices.
