Constructor & Destructor Documentation

ObjSepa()

scip::ObjSepa::ObjSepa ( SCIP *  scip, const char *  name, const char *  desc, int  priority, int  freq, SCIP_Real  maxbounddist, SCIP_Bool  usessubscip, SCIP_Bool  delay  )

inline

default constructor

Parameters

scip	SCIP data structure
name	name of cut separator
desc	description of cut separator
priority	priority of the cut separator
freq	frequency for calling separator
maxbounddist	maximal relative distance from current node's dual bound to primal bound compared to best node's dual bound for applying separation
usessubscip	does the separator use a secondary SCIP instance?
delay	should separator be delayed, if other separators found cuts?
