I'm modeling a flow problem on graph using sage. Once the graph was ready I've modeled a MILP problem with constraints. I've problems having unique variables.
What I do is to use v = p.new_variable() and subsequently use the v variable in a loop iterating the edges of the graph in such as: for origin, destination, attributes in G.edges(): attributes['v_component_for_that_edgs'] = v[('origin', 'destination')] But at the end some variable are duplicate! The code producing that strange behavior is attached to this mail. Is an error of mine or a Sage problem? Thanks. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
