SYMbuildDejavuGraph()

SCIP_RETCODE SYMbuildDejavuGraph	(	SCIP *	scip,
		dejavu::static_graph *	dejavugraph,
		SYM_GRAPH *	graph,
		SCIP_Bool *	success
	)

compute generators of symmetry group

Parameters

SYMbuildDejavuGraphCheck()

SCIP_RETCODE SYMbuildDejavuGraphCheck	(	SCIP *	scip,
		dejavu::static_graph *	dejavugraph,
		SYM_GRAPH *	G1,
		SYM_GRAPH *	G2,
		int *	nnodes,
		int *	nnodesfromG1,
		SCIP_Bool *	success
	)

returns whether two given graphs are identical

Parameters

scip	SCIP pointer
dejavugraph	pointer to hold dejavu graph being created
G1	first graph
G2	second graph
nnodes	pointer to store number of nodes in dejavu graph
nnodesfromG1	pointer to store number of nodes in dejavu graph arising from G1
success	pointer to store whether dejavugraph could be built
