Detailed Description

A Sepset is a Node which contains subnodes. Every Sepset sits between 2
Cliques in a JoinTree. The subnodes set of a sepset is the intersection
of the subnodes sets of those two Cliques. The potential of a sepset
pertains to its subnodes. A sepset is used when passing messages between
its two cliques.

Attributes
----------
clique_x : Clique
clique_y : Clique
cost : float
flag : bool
mass : float
potential : Potential
subnodes : set[Node]

id_nym : int
topo_index : int
name : str
neighbors : set[Node]
visited : bool

Constructor & Destructor Documentation

def graphs.Sepset.Sepset.__init__	(		self,
			id_num,
			clique_x,
			clique_y,
			subnodes
	)

Constructor


Parameters
----------
id_num : int
clique_x : Clique
clique_y : Clique
subnodes : set[BayesNode]
    the intersection of the subnodes of clique_x and clique_y.

Returns
-------

Member Function Documentation

def graphs.Sepset.Sepset.__lt__	(		self,
			other
	)

Overrides <. Used by JoinTree to order sepsets
in a priority queue.

Parameters
----------
other : Sepset

Returns
-------
bool

def graphs.Sepset.Sepset.create_sepset_heap (   cliques )

static

Create a sepset (with a unique id) for every pair of cliques in
'cliques' that have a non-empty intersection. Insert those sepsets
into a priority queue.

Parameters
----------
cliques : list[Clique]

Returns
-------
list

def graphs.Sepset.Sepset.get_other_clique	(		self,
			clique
	)

If 'clique' is clique_x or clique_y, then return the other one.

Parameters
----------
clique : Clique

Returns
-------
Clique

def graphs.Sepset.Sepset.set_pot_to_one	(		self,
			is_quantum
	)

Sets self.potential to one. Needs to know is_quantum to decide
whether to use a numpy array with float64 or complex128 entries.
Sets pot to one over all states, not just the active ones.

Parameters
----------
is_quantum : bool

Returns
-------
None
