downdbvalid

SCIP_Bool BRANCHINGDECISION::downdbvalid

Indicator for the validity of the downdb value. Is FALSE, if no actual branching occurred or the value was determined by an LP not solved to optimality.

boundsvalid

SCIP_Bool BRANCHINGDECISION::boundsvalid

are variable bounds for down and up child valid?

boundssize

int BRANCHINGDECISION::boundssize
