constructor with a given graph

Parameters

graph	the graph to be triangulated, i.e., the nodes of which will be eliminated
domsizes	the domain sizes of the nodes to be eliminated
sequence	the order in which the nodes should be eliminated
elimSeq	the elimination sequence used to triangulate the graph. Only a reference/pointer to the sequence passed in argument is kept in the current class.
JTStrategy	the junction tree strategy used to create junction trees
minimality	a Boolean indicating whether we should enforce that the triangulation is minimal w.r.t. inclusion

Warning: Note that we allow dom_sizes to be defined over nodes/variables that do not belong to graph. These sizes will simply be ignored. However, it is compulsory that all the nodes of graph belong to dom_sizes; note that, by aGrUM's rule, the graph, the domain sizes and the elimination sequence are not copied but only referenced by the triangulation algorithm.

Member Function Documentation

◆ _initTriangulation()

void gum::OrderedTriangulation::_initTriangulation ( UndiGraph & graph )

finalprotectedvirtual

the function called to initialize the triangulation process

This function is called when the triangulation process starts and is used to initialize the elimination sequence strategy. Actually, the graph that is modified by the triangulation algorithm is a copy of the original graph, and this copy need be known by the elimination sequence strategy. _initTriangulation is used to transmit this knowledge to the elimination sequence (through method setGraph of the elimination sequence class).

Parameters

graph the very graph that is triangulated (this is a copy of _original_graph)

Reimplemented from gum::StaticTriangulation.

indicates wether minimality is required

◆ junctionTree()

const CliqueGraph& gum::StaticTriangulation::junctionTree ( )

virtualinherited

returns a compatible junction tree

inherited

returns the junction tree strategy used by the triangulation

◆ maxLog10CliqueDomainSize()

double gum::Triangulation::maxLog10CliqueDomainSize ( )

inherited

returns the max of log10DomainSize of the cliques in the junction tree.

This is usefull for instance to estimate the complexity (both in space and in time) of the inference that will use the junction tree.

This method is not 'const' since it can be called before building any junction tree and hence it needs to build it...

◆ maxPrimeSubgraphTree()

const CliqueGraph& gum::StaticTriangulation::maxPrimeSubgraphTree ( )

virtualinherited

returns a junction tree of maximal prime subgraphs

Warning: Actually, the cliques of the junction tree are guarranteed to be maximal prime subgraph of the original graph that was triangulated only if the triangulation performed is minimal (in the sense that removing any edge in the triangulated graph results in a nontriangulated graph). This can be ensured by requiring minimality of the triangulation.

Implements gum::Triangulation.

◆ newFactory()

OrderedTriangulation * gum::OrderedTriangulation::newFactory ( ) const

finalvirtual

returns a fresh triangulation over the same graph and of the same type as the current object (using the same sequence, etc.)

virtual copy constructor

note that we return a pointer as it enables subclasses to return pointers to their types, not Triangulation pointers. See item 25 of the more effective C++.

◆ setGraph()

void gum::OrderedTriangulation::setGraph	(	const UndiGraph *	graph,

initialize the triangulation data structures for a new graph

Parameters

Warning: note that, by aGrUM's rule, the graph and the domain sizes are not notcopied but only referenced by the triangulation algorithm.
