Constructor & Destructor Documentation

ObjBranchrule() [1/3]

scip::ObjBranchrule::ObjBranchrule ( SCIP *  scip, const char *  name, const char *  desc, int  priority, int  maxdepth, SCIP_Real  maxbounddist  )

inline

default constructor

Parameters

scip	SCIP data structure
name	name of branching rule
desc	description of branching rule
priority	priority of the branching rule
maxdepth	maximal depth level, up to which this branching rule should be used (or -1)
maxbounddist	maximal relative distance from current node's dual bound to primal bound compared to best node's dual bound for applying branching rule (0.0: only on current best node, 1.0: on all nodes)

Member Function Documentation

operator=() [1/2]

ObjBranchrule & scip::ObjBranchrule::operator= ( const ObjBranchrule &  o )

delete

assignment of polymorphic classes causes slicing and is therefore disabled.

operator=() [2/2]

ObjBranchrule & scip::ObjBranchrule::operator= ( ObjBranchrule &&  o )

delete

assignment of polymorphic classes causes slicing and is therefore disabled.
