get_bipartite_incidence_graph

(function from pyomo.contrib.incidence_analysis.interface)

pyomo.contrib.incidence_analysis.interface.get_bipartite_incidence_graph(variables, constraints, **kwds)[source]

Return the bipartite incidence graph of Pyomo variables and constraints.

Each node in the returned graph is an integer. The convention is that, for a graph with N variables and M constraints, nodes 0 through M-1 correspond to constraints and nodes M through M+N-1 correspond to variables. Nodes correspond to variables and constraints in the provided orders. For consistency with NetworkX’s “convention”, constraint nodes are tagged with bipartite=0 while variable nodes are tagged with bipartite=1, although these attributes are not used.

Parameters:

  • variables (List of Pyomo VarData objects) – Variables that will appear in incidence graph

  • constraints (List of Pyomo ConstraintData objects) – Constraints that will appear in incidence graph

  • include_fixed (Bool) – Flag for whether fixed variable should be included in the incidence

Return type:
