Field Documentation

objval

SCIP_Real BRANCHINGRESULTDATA::objval

The objective value of the solved lp. Only contains meaningful data, if cutoff == FALSE.

dualbound

SCIP_Real BRANCHINGRESULTDATA::dualbound

The best dual bound for this branching, may be changed by deeper level branchings.

niterations

SCIP_Longint BRANCHINGRESULTDATA::niterations

The number of probing iterations needed in sub branch.

cutoff

SCIP_Bool BRANCHINGRESULTDATA::cutoff

Indicates whether the node was infeasible and was cutoff.

dualboundvalid

SCIP_Bool BRANCHINGRESULTDATA::dualboundvalid

Is the value of the dual bound valid? That means, was the according LP or the sub problems solved to optimality?

bestgain

SCIP_Real BRANCHINGRESULTDATA::bestgain

best gain (w.r.t. to the base lp) on the lowest level below this child

totalgains

SCIP_Real BRANCHINGRESULTDATA::totalgains

sum over all gains that are valid in both children

ntotalgains

int BRANCHINGRESULTDATA::ntotalgains

number of gains summed in totalgains
