Hello,
I have defined a polyhedron by a collection of linear inequalities over
three variables, and it's all lovely: I can access the vertices, draw all
sorts of nice pictures, get all sorts of information. The one problem is
the vertex graph. If my polyhedron is P, say, then P.vertex_graph() gives
me a graph where each vertex is labelled something like "A vertex at
(0,1,0)". This seems somewhat redundant labelling, and ideally I'd like to
relabel the vertices to simply "(0,1,0)".
I attempted to relabel the vertex graph with:
dict ={i:j, for (i,j) in zip(P.vertices(),P.vertex_list())
G = P.vertex_graph()
G.relabel(dict)
However, that attempt produced the error:
TypeError: unhashable type: 'list'
I'm not sure how to go about this relabelling... any idea? Thanks!
