Description
This type represents a node of a chordal network.
Each node of the network has the following properties:
-
equations: a set of polynomials F
-
inequations: a set of polynomials H
-
rank: a variable of the polynomial ring
-
label: a string that uniquely identifies the node (only needed for visualization)
These properties can be accessed with the functions:
gens,
ineqs,
rank,
labelThe incoming/outgoing arcs of a node can be obtained as
