Member Data Documentation

std::vector< DecompObjBound > DecompNodeStats::objHistoryBound

Storage of the bounds.

For the continuous part: CPM : Bounds on the objective of optimal master linear relaxation. Typically, this is an LP solved to optimality, so, LB = zCP = UB. PC/RC: Given bounds on the objective of optimal restricted master linear relaxation zPC_LB <= zPC* <= zPC_UB and a lower bound on the most negative reduced cost (RC_LB) extreme point (ray) from the subproblem polytope (for the associated master duals). LB = zPC_LB + RC_LB <= zPC* <= zPC_UB = UB
